Striped maple trees (Acer pensylvanicum) are also known as “snakebark maple.” But don’t let this scare you away. This lovely little tree is an American native. Other species of snakebark maple exist, but Acer pensylvanicum is the only one native to the continent. For more striped maple tree information and tips for striped maple tree cultivation, read on.
Striped Maple Tree Information All maples are not soaring, graceful trees with snow-white bark. According to striped maple tree information, this tree is a shrubby understory maple. It can be grown as a large shrub or a small tree. You’ll find this maple in the wild from Wisconsin to Quebec, from the Appalachians into Georgia. It is native to the rocky forests in this range. These trees usually grow from 15 to 25 feet tall, although some specimens get to 40 feet tall. The canopy is rounded and sometimes the very top is flattened. The tree is much loved because of the unusual and interesting trunk. Striped maple tree bark is green with vertical white striping. The stripes sometimes fade as the tree matures, and the striped maple tree bark turn reddish brown.
Additional facts about striped maple trees include their leaves which can grow quite long, up to 7 inches. Each one has three lobes and looks a little like a goose foot. The leaves grow in pale green with pink overtones, but turn a deep green by summer’s end. Expect another color change in autumn when the foliage turns canary yellow. In May, you’ll see drooping racemes of tiny yellow flowers. These are followed by winged seed pods as summer passes. You can use the seeds for striped maple tree cultivation.
Striped Maple Tree Cultivation If you are thinking of planting striped maple trees, they grow best in shaded areas or woodland gardens. As is typical with understory trees, striped maple trees prefer a shady location and cannot grow in full sun. Striped maple tree cultivation is easiest in well-drained soil. The soil need not be rich, but the trees thrive in moist soils that are slightly acidic.
One good reason for planting striped maple trees is to benefit local wildlife. This tree serves an important role as a browse plant for wildlife. Planting striped maple trees results in food for various animals, including red squirrels, porcupines, white-tailed deer and ruffed grouse.

Jack Frost maple trees are hybrids developed by Oregon’s Iseli Nursery. They are also known as Northwind maples. The trees are small ornamentals that are more cold hardy than regular Japanese maples. For more Northwind maple information, including tips for growing Northwind maples, read on.
Northwind Maple Information Jack Frost maple trees are crosses between Japanese maples (Acer palmatum) and Korean maples (Acer pseudosieboldianum). They have the beauty of the Japanese maple parent, but the Korean maple’s cold tolerance. They were developed to be extremely cold hardy. These Jack Frost maple trees thrive in USDA zone 4 in temperatures down to -30 degrees Fahrenheit (-34 C.). The official cultivar name for Jack Frost maple trees is NORTH WIND® maple. The scientific name is Acer x pseudosieboldianum. These trees can be expected to live for 60 years or more.
The Northwind Japanese maple is a small tree that usually doesn’t get taller than 20 feet (6 m.). Unlike its Japanese maple parent, this maple can survive in to zone 4a without any signs of dieback. Northwind Japanese maples are truly lovely little deciduous trees. They add color charm to any garden, no matter how small. The maple leaves appear in spring a brilliant orange-red. They mature into light green, then blaze into crimson in the autumn.
Growing Northwind Maples These maple trees have low canopies, with the lowest branches only a few feet above the soil. They grow moderately fast. If you live in a chilly area, you may be thinking of growing Northwind Japanese maple trees. According to Northwind maple information, these cultivars make an excellent substitute for less hardy Japanese maples in zone 4. Can you start growing Northwind maples in warmer regions? You can try, but success is not guaranteed. There is not a lot of information about how heat tolerant these shrubs are.
This tree prefers a site offering full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. Northwind Japanese maples are otherwise not picky. You can grow them in soil of almost any pH range as long as the soil is moist and well drained, and is somewhat tolerant of urban pollution.

You’ve heard of silver maples and Japanese maples, but what is a Korean maple? It’s a small maple tree that makes a wonderful substitute for Japanese maple in colder regions. For more Korean maple information and tips on how to grow a Korean maple, read on.
What is a Korean Maple? Korean maple trees (Acer pseudosieboldianum) look quite a bit like the popular Japanese maples, but they are hardier. The trees thrive in U.S. Department of Agriculture plant hardiness zones 4 through 8. The tree is native to China and Korea, where it grows in forested areas. This small specialty maple matures to about 25 feet tall (7.6 m.) and wide.
Korean Maple Information The Korean maple is a delicate tree with some exceptional features. In spring when new leaves open, they are soft and downy. Each has some 10 lobes and is about as wide as your hand. The blossoms appear in spring as well, hanging in surprising purple clusters. They develop into the tree’s fruits, winged samaras, in summer. A big attraction of the tree is its spectacular fall color. The dark green leaves flame into shades of orange, purple, yellow, red and crimson as the weather gets chilly in autumn.
How to Grow a Korean Maple If you want to grow a Korean maple, find a site with moist, organically rich soil and excellent drainage. Korean maple trees will not be happy with wet feet. You can plant these beauties in a full sun area or a spot with sun-dappled shade. Don’t pick a site that is hot and dry.
Caring for Korean Maples Once you have your tree started, caring for Korean maples includes watering. These are quite thirsty trees and require regular irrigation. Provide Korean maple trees with water every week throughout the growing season, but offer extra water during dry periods. You’ll also need to protect these trees from strong winds. Protection is also required in the coldest zones.
You won’t have to worry much about insect or disease problems. While the trees are susceptible to stem canker, leaf spots and anthracnose, they do not have any serious pest or disease issues.

The mahogany tree (Swietenia mahagnoni) is such a lovely shade tree that it’s too bad it can only grow in USDA zones 10 and 11. That means that if you want to see a mahogany tree in the United States, you’ll need to head to Southern Florida. These attractive, fragrant trees form rounded, symmetrical crowns and make excellent shade trees. For more information about mahogany trees and mahogany tree uses, read on.
Mahogany Tree Information If you read information about mahogany trees, you’ll find them both interesting and attractive. The mahogany is a large, semi-evergreen tree with a canopy that casts dappled shade. It is a popular landscape tree in Southern Florida. Mahogany tree facts describe the trees as being very tall. They can grow 200 feet in height with leaves some 20 inches long, but it’s more common to see them growing to 50 feet or less. Mahogany tree information suggests that wood is dense, and the tree can hold its own in strong winds. This makes it useful as a street tree, and trees planted in medians form attractive canopies overhead.
Additional Mahogany Tree Facts Mahogany tree information includes a description of the blossoms. These heat-loving ornamentals produce small, fragrant clusters of flowers. The blossoms are either white or yellow-green and grow in clusters. Both male and female flowers grow on the same tree. You can tell male from female flowers because male stamens are tube-shaped. The flowers bloom in late spring and early summer. Moths and bees love the flowers and serve to pollinate them. In time, woody fruit capsules grow in and are brown, pear-shaped and five inches long. They are suspended from fuzzy stalks in winter. When they split, they release the winged seeds that propagate the species.
Where Do Mahogany Trees Grow? Where do mahogany trees grow, gardeners ask. Mahogany trees thrive in very warm climates. They are native to South Florida as well as the Bahamas and the Caribbean. The tree is also nicknamed Cuban mahogany and West Indian mahogany. They were introduced into Puerto Rico and the Virgin Islands over two centuries ago. Mahogany trees continue thriving in those places.
Mahogany tree uses vary from the ornamental to the practical. First and foremost, mahogany trees are used as shade and ornamental trees. They are planted in backyards, parks, on medians and as street trees. The trees are also raised and felled for their hard, durable wood. It is used to make cabinets and furniture. The species is getting increasingly rare and has been added to Florida’s endangered species list.

What is a madrone tree? Pacific madrone (Arbutus menziesii) is a dramatic, unique tree that provides beauty to the landscape all year long. Keep reading to learn what you need to know to grow madrone trees.
Madrone Tree Facts Pacific madrone is native to the coastal ranges of the Pacific Northwest, from northern California to British Columbia, where winters are wet and mild and summers are cool and dry. It tolerates occasionally chilly weather, but isn’t highly frost-resistant. Pacific madrone is a versatile, relatively slow-growing tree that reaches heights of 50 to 100 feet or more in the wild, but usually tops out at only 20 to 50 feet in home gardens. You may also find it listed as bayberry or strawberry tree.
Native Americans ate the rather bland, reddish-orange berries fresh. The berries also made good cider and were often dried and pounded into meal. Tea brewed from the leaves and bark was used medicinally. The tree also provided sustenance and protection for a variety of birds, and for other wildlife. Bees are attracted to the fragrant white flowers. The interesting, peeling bark provides texture to the garden, although the bark and leaves can create litter that may require a bit of raking. If you want to grow madrone trees, consider planting in a natural or wild garden, as the tree may not fit in well to a perfectly manicured yard. A dry, somewhat neglected area is best.
Growing Madrone Trees Madrone tree information tells us that Pacific madrone is notoriously difficult to transplant, probably because in its natural environment, the tree is dependent on certain fungi in the soil. If you have access to a mature tree, see if you can “borrow” a shovelful of the soil under the tree to mix into the soil where you plant the seedlings. Also, Oregon State University Extension advises gardeners to purchase seedlings with the north/south orientation marked on the tube so you can plant the tree facing its accustomed direction. Purchase the smallest seedlings you can find, as larger trees don’t appreciate having their roots disturbed.
You can also plant seeds. Harvest ripe fruit in fall or early winter, then dry the seeds and store them until planting time in spring or autumn. For best results, chill the seeds for a month or two before planting. Plant the seeds in a container filled with a mix of clean sand, peat and gravel. Madrones prefer full sun and require excellent drainage. In the wild, Pacific madrone thrives in dry, rocky, inhospitable areas.
How to Care for a Madrone Tree Madrone trees don’t do well in a well-watered, manicured garden and they don’t appreciate being fussed over. Keep the soil slightly moist until the roots are established, and then leave the tree alone unless the weather is unseasonable hot and dry. In that case, an occasional watering is a good idea.

Also known as red palm or red sealing wax palm, lipstick palm (Cyrtostachys renda) is appropriately named for its distinctive, bright red fronds and trunk. Lipstick palm is considered by many to be one of the world’s most beautiful and exotic palms. If you live in USDA plant hardiness zone 10b or above, where temperatures never drop below 40 F. (4.5 C.), you can grow this stunning palm in your own garden. Read on for more lipstick palm information.
Lipstick Palm Information Lipstick palm is a tropical plant native to Malaysia, Borneo, Southern Thailand and Sumatra, where it grows in swampy areas, along riverbanks and in coastal tidal areas. It is threatened in some areas due to reduction of lowland forests. Red sealing wax palm reaches heights of up to 50 feet in its natural environment, but usually tops out at about 25 to 30 feet in the home garden.
How to Grow Lipstick Palms Lipstick palm growing conditions includes partial shade while the plant is young. Otherwise, mature trees thrive in full sunlight. This warm climate tree prefers year round temperatures between 75 and 85 F. (24-29 C.). Red sealing wax palm doesn’t grow well in dry soil and isn’t tolerant of strong winds. It requires high humidity and even grows in swampy conditions or standing water, making this palm a useful pond plant.
Although lipstick palm can be started by seed, it’s much easier and faster to remove and replant suckers from the side of an established tree. If you’re adventurous and want to try your hand at growing lipstick palm from seeds, remove dry seedheads from a plant, then remove the seeds and plant them in a planting media with excellent moisture retention. Germination generally takes at least two to four months, and seeds may not sprout for up to nine months.
Lipstick Palm Plant Care As mentioned above, the main challenge when it comes to lipstick palm plant care is keeping the soil consistently moist. Otherwise, lipstick palm requires little attention. Although lipstick palm can be grown in a container indoors, most growers find it extremely difficult to maintain adequate humidity and warmth to sustain the plant.

Flat stems of feathery, blue-green foliage and ornamental bark combine to make Leyland cypress an appealing choice for medium to large landscapes. Leyland cypress trees grow three feet or more per year, making it an excellent choice for a quick specimen or lawn tree, or a privacy hedge. Information about Leyland cypress will help with growing healthy trees.
Information About Leyland Cypress Leland cypress (x Cupressocyparis leylandii) is a rare, but successful, hybrid between two different genera: Cupressus and Chamaecyparis. Leyland cypress has a short lifespan for an evergreen tree, surviving for 10 to 20 years. This tall evergreen conifer is grown commercially in the Southeast as a Christmas tree. The tree grows to a height of 50 to 70 feet, and although the spread is only 12 to 15 feet, it may overwhelm small, residential properties. Therefore, larger areas are most suitable for growing a Leyland cypress tree. The tree is also useful in coastal landscapes where it tolerates salt spray.
How to Grow Leyland Cypress Trees Leyland cypress trees need a location in full sun or partial shade and a rich, well-drained soil. Avoid windy sites where the tree may be blown over. Plant the tree so that the soil line on the tree is even with the surrounding soil in a hole about twice as wide as the root ball. Backfill the hole with the soil that you removed from it without amendments. Press down with your foot as you fill the hole to remove any air pockets that may be present.
Leyland Cypress Care Leyland cypress trees need very little care. Water them deeply during prolonged drought, but avoid overwatering, which can lead to root rot. The tree doesn’t need regular fertilization. Watch for bagworms and, if possible, remove the bags before the larvae they contain have a chance to emerge.
Growing a Leyland Cypress Pruned Hedge Its narrow, columnar growth pattern makes Leyland cypress ideal for use as a hedge to screen out unsightly views or protect your privacy. To form a pruned hedge, set out the trees with 3 feet of space between them. When they reach a height about a foot beyond the desired height of the hedge, top them to about 6 inches below that height. Prune the shrubs every year in midsummer to maintain the height and shape the hedge. Pruning during damp weather, however, can lead to disease.

Leyland Cypress (x Cupressocyparis leylandii) is a large, fast-growing, evergreen conifer that can easily reach 60-80’ in height and 20’ wide. It has a natural pyramidal shape and elegant, dark green, fine-textured foliage. When they become too large or unsightly, trimming Leyland Cypress trees becomes necessary.
Leyland Cypress Pruning Leyland Cypress is often used as a quick screen because it can grow up to 4 feet per year. It makes an excellent windbreak or property boundary border. Because it is so large, it can quickly outgrow its space. For this reason, the native East Coast specimen looks best on large lots where it is allowed to maintain its natural form and size. Since Leyland Cypress grows so wide, do not plant them too close together. Space them at least 8 feet apart. Otherwise, the overlapping, scraping branches can wound the plant and, therefore, leave an opening for disease and pests. In addition to proper location and spacing, pruning Leyland Cypress is occasionally needed – especially if you don’t have enough room or if it’s outgrown the allotted space.
How to Trim a Leyland Cypress Tree Pruning Leyland Cypress into a formal hedge is a common practice. The tree can take severe pruning and trimming. If you are wondering when to prune Leyland Cypress, then summer is your best time frame. During the first year, trim the top and sides to start forming the shape you desire. During the second and third year, trim just the side branches that have wandered out too far to maintain and encourage foliage density.
Leyland Cypress pruning changes once the tree reaches the desired height. At that point, annually trim the top six to twelve inches below the desired height. When it regrows, it will fill in more thickly.

Gardeners in need of quick privacy hedges love quick-growing Leyland cypress (x Cupressocyparis leylandii). When you plant them in an appropriate location and provide good culture, your shrubs may not suffer from Leyland cypress diseases. Read on for information about the main diseases of Leyland cypress trees, including tips on treating disease in Leyland cypress plants.
Preventing Leyland Cypress Diseases Prevention is easier than cure when it comes to diseases of Leyland cypress trees. Your first, best steps toward keeping these attractive evergreens healthy is planting them in appropriate sites. The second step is giving them the best care. A healthy, vigorous plant shakes off problems with more ease than a stressed plant. And Leyland cypress disease treatment is often impossible or ineffective. So save yourself the time and effort involved in treating disease in Leyland cypress. Plant these shrubs in a sunny location in soil offering excellent drainage. Space them far enough apart to let air pass between them. Provide water during times of drought and check your hardiness zone. Leyland cypress thrive in U.S. Department of Agriculture plant hardiness zones 6 through 10.
Diseases of Leyland Cypress Trees If your shrubs are ill, you’ll have to learn something about the different Leyland cypress diseases to figure out what’s wrong. Diseases of Leyland cypress generally fall into three categories: blights, cankers and root rots. Blight The symptoms of needle blight diseases include needles browning and dropping. Usually, this begins on the lower branches. These are fungal diseases, and the spores spread from branch to branch by rain, wind and tools. Placing the shrubs far enough apart to allow air and sun to get through the branches helps prevent needle blight. If it’s too late for prevention, prune out infected branches. Thorough application of a fungicide can help but is difficult on tall specimens.
Canker If your Leyland cypress needles turn red-brown or you see cankers on the trunks or branches, the shrubs may have a canker disease, like Seiridium or Botryosphaeria canker. Cankers are dry lesions, often sunken, on stems and branches. Surrounding bark can show a dark brown or purplish discoloration. Canker diseases are also caused by fungus, and usually only attack stressed plants. When it comes to treating disease in Leyland cypress, fungicides are not effective. The only Leyland cypress disease treatment for this is to prune out infected branches, being sure to sterilize the pruners. Then start a program of regular irrigation.
Root rot Root rot diseases cause dying roots leading to yellowing foliage. It is often caused by inappropriate planting in an area where the soil does not drain well. Once a shrub has root rot, chemical Leyland cypress disease treatment is not effective. As with the other diseases, the best way of treating disease in Leyland cypress is to give the plants appropriate cultural care.

If you love the effect of an evergreen tree and the brilliant color of a deciduous tree, you can have both with larch trees. These needled conifers look like evergreens in spring and summer, but in the fall the needles turn golden yellow and drop to the ground.
What is a Larch Tree? Larch trees are large deciduous trees with short needles and cones. The needles are only an inch or so long, and sprout in little clusters along the length of the stems. Each cluster has 30 to 40 needles. Tucked in among the needles you can find pink flowers that eventually become cones. The cones start out red or yellow, turning to brown as they mature. Native to many parts of Northern Europe and Asia as well as Northern parts of North America, larches are happiest in cold climates. They grow best in mountainous areas but tolerate any cool climate with plenty of moisture.
Larch Tree Facts Larches are tall trees with a widespread canopy, best suited to rural landscapes and parks where they have plenty of room to grow and spread their branches. Most larch tree types grow between 50 and 80 feet tall and spread as much as 50 feet wide. The lower branches may droop while the mid-level branches are nearly horizontal. The overall effect is similar to that of a spruce. Deciduous conifers are rare finds, and they are well worth planting if you have the right location. Although most are massive trees, there are a few types of larch trees for gardeners with less space. Larix decidua ‘Varied Directions’ grows 15 feet tall with irregular branches that give it a distinctive winter profile. ‘Puli’ is a dwarf European larch with lovely weeping branches held close to the trunk. It grows up to 8 feet tall, and 2 feet wide.
Here are some standard-sized larch tree varieties: European larch (Larix decidua) is the largest species, said to grow up to 100 feet tall, but rarely exceeds 80 feet in cultivation. It is known for its brilliant fall color. Tamarack (Larix laricina) is a native American larch tree that grows up to 75 feet tall. Larix decidua ‘Pendula’ is a shrubby larch that becomes a ground cover if not staked upright. It spreads as much as 30 feet.
Growing a larch tree is as snap. Plant the tree where it can get at least six hours of sunlight per day. It can’t tolerate hot summers and should not be planted in U.S. Department of Agriculture zones warmer than 6. Frozen winters aren’t a problem. Larches won’t tolerate dry soil, so water often enough to keep the soil moist. Use organic mulch to help the soil hold moisture.
