Succulents may be most commonly grown in containers. However, they’re ideal for outdoor rock gardens and sculptural gardens. They can even serve as ground cover in rocky or sandy soils. If you don’t have garden space, grow succulents vertically outdoors. Living wall planters can be made from old pallets, picture frames, fence slats or shutters. Below are some of the most popular succulents for growing outdoors. [图片]Agave: Some people refer to Agave plants as “dinosaur plants”. They look like massive versions of the Aloe plant, except the Agave leaves are grayer. This standout succulent makes a fantastic focal point in any yard. Agave grows more quickly in the ground than in containers. It does best when you ignore it. It prefers rocky or sandy soil and isn’t picky about the soil’s pH. You don’t want to fertilize an Agave plant. If it gets too much nourishment, it will bloom. Although the flowers can be massive and beautiful, the plant dies after it blooms.[图片]Watch Chain Plant (Crassula muscosa): This plant is referred to as a “Watch Chain” or “Zipper Plant” because of the way it creates intricate braid-like patterns as it grows. The small, green leaves are crowded around a narrow stem. This succulent is easy to grow. In fact, it can take over your garden if that’s what you want. It’s perfect for people who don’t want to spend a lot of time tending to their gardens.[图片]Dasylirion: These stunning plants resemble a lion’s mane or palm tree. Many people are surprised to find out that the Dasylirion is a succulent. Dasylirion grows well in USDA plant hardiness zone 8 to 11. It develops into a bushy sphere up to 4 feet (1.2 m) in diameter. The spiny leaves grow out of a trunk that grows into a thick cylinder. You can keep the plant from looking too unkempt by stripping the lower leaves around the trunk.

Some succulents are better suited for the indoors. Some people prefer those with soft leaves for houseplants. Plants with spiny thorns can hurt if you brush against them. You may also want mini succulents for your indoor houseplants. Below are some of the most popular types of indoor succulents. [图片]Jade Plant (Crassula ovata): Chances are you’ve seen a Jade Plant before. Some say that this plant symbolizes wealth. The leaves are oval-shaped and extremely plump. They’re thick, glossy and attractive. The leaves usually stay green. However, they may turn slightly red. Finger Jade has thick, juicy stems, but the leaves don’t form ovals. Instead, they look like stubby fingers. This type of plant has been nicknamed “Hobbit Jade” or “ET’s Fingers.” Jade Plants don’t like a lot of water. They become top heavy and can fall over if they don’t get the right nutrients. Keep the soil dry, and prune them as necessary so that their stems don’t break under their own weight.[图片]Burro’s Tail (Sedum morganianum): This plant’s stems trail downward. Therefore, plant it in a tall container or hanging basket. The thick, round leaves have a neutral grayish-green color. The stems to which the leaves connect can grow up to two feet long. You’ll need plenty of space in which to grow this plant. The leaves can fall off if they’re disturbed. You’ll also need plenty of sunlight. However, if you choose to move it outdoors in warmer weather, make sure that it can handle the sun and the temperature before committing.[图片]Zebra Plant (Haworthia fasciata) The Zebra Plant is perfect for people who don’t have a lot of space or don’t have an ideal indoor spot for a houseplant. This succulent has a small footprint and grows upward with long, triangular leaves. Each leaf is ringed with several white bands that make it resemble a zebra. You can plant it in a shallow container. Keep it in indirect light. Too much sunlight will cause it to wither. Aloe Vera is a common houseplant that looks great and has health benefits for humans. This plant can take a long time to grow and mature. If you’re using it for the healing benefits of the gel that’s found inside the leaves, you might want to grow several plants at once. It does create offsets. You can re-pot the offsets to cultivate more plants.

Succulents may have color in their outer flesh. Some varieties grow flowers that bloom separately from the plump, juicy “leaves”. We’ll talk about those later in the article. Below, you can read about succulents that have colorful foliage. [图片]Red Pencil Plant (Euphorbia tirucalli ‘Rosea’): This plant has long, finger-like branches and resembles undersea coral. It can look as though its appendages are on fire as they transform from green to magenta to yellow. The height of this plant creates interest in a container garden. It grows upward instead of branching out horizontally, which can look impressive in a tight space. Golden Toothed Aloe (Aloe nobilis): You might be familiar with the green Aloe plant. This fiery variety has dark green leaves with sharp white teeth on the edges. The leaves turn burnt orange and red under bright sunlight. In the summer, reddish-orange flowers extend on long stems. Hummingbirds love these vibrant blooms.[图片]Royanum Hens and Chicks (Sempervivum tectorum ‘Royanum’): This plant fills up as it grows offsets in the spring. It propagates itself and looks great in bunches. It forms a mat in your container or garden. The leaves are lime green, but the tips of this variety vary from dark burgundy to chocolate. This plant sends up star-shaped flowers. After it blooms, it dies. However, the offsets carry on the life cycle. Paddle Plant (Kalanchoe luciae) The nicknames for this succulent are as colorful as its leaves. It has been referred to as flipping flapjacks and desert cabbage. The leaves are huge, round and smooth. They grow red in the sun and become more vibrant as winter comes. Morning Light Echeveria (Echeveria ‘Morning Light’): This succulent looks like a lotus blossom. However, the leaves, not the flowers, make up the lovely pattern with their delicate pastels. The hue is subtle. It changes from light bluish-violet toward the core to pretty pink at the tips of the leaves. This one is easy to grow. It likes indirect light. Unlike some other succulents, this plant does require nutrient-rich soil.

If you’ve been anywhere near Pinterest, a hobby shop or a home improvement store lately, you have probably noticed that succulents have been quite trendy for a while. These versatile plants are incredibly easy to care for. They make for stylish decor indoors and out. We’re spelling out everything you need to know about them. [图片]What is a Succulent? Succulents are plants that store water. One of the succulents with which people are most familiar is the cactus. However, many families of plants have succulents within them. These types of plants are typically found in hot climates with low levels of precipitation. Succulents have plump areas in their leaves. These parts retain water in dry climates, allowing the plant to access moisture even when there is a lack of rainfall. Succulents can thrive even on the slightest mist. [图片]Growing succulents has become a fashionable hobby. People trade them and talk about them endlessly in online forums. You can plant them inside the home or in an outdoor garden. Some say that they thrive on neglect. You don’t even need to plant them in soil. While succulents can grow in a container or garden, they can also grow in cracks in stones and sand. Although they’re relatively easy to grow and care for, succulents don’t like extreme cold. They also may deteriorate in wet conditions. However, they can tolerate more sun and heat than other plants. They can also endure some cold and rain. [图片]Different Varieties Although many people think that succulents are simply cacti, succulents are found in 60 different families of plants. Most of them belong to the following families: Aizoaceae: Most of the plants in this family are native to Africa. However, some are found in Australia and the Pacific. Some are referred to Stone Plants or Ice Plants. The leaves of Tetragonia tetragonioides are sometimes used as an alternative to spinach in salads. Asparagaceae: The Agave, Yucca fall into this category. Cactaceae: The cactus is a member of this plant family. Almost all cacti are native to the Americas. Most cacti have ribbed exteriors that let the plant expand during periods of heavier watering. Crassulaceae: This family may be the most frost-hardy variety. They add an exotic touch to any indoor or outdoor garden. They come in a wide variety of shapes and colors. Some succulents have sharp spines on their leaves. However, others are soft and smooth or even faintly hairy.

We have touched on specific ways to care for certain types of succulents in Ultimate Guide to Succulents: Types of Succulents. Some care instructions depend on your zone or whether the plant is outdoors or in a container. General guidelines for succulent care are below. [图片]How Often To Water Most succulents don’t need a lot of water. The general rule is to let the top half of the soil dry out before you water it again. In the summer, outdoor succulents generally need to be watered once a week. Water container plants two or three times a week. You’ll usually reduce irrigation in lower temperatures even for indoor houseplants. However, different varieties of succulents require different amounts of water. Check with a local nursery or the company from which you bought the plant for specific watering instructions. [图片]Propagating Succulents are best grown from offsets or propagated leaves. If your plant sends out “pups”, you can remove those smaller “babies” and replant them. You can also propagate the plants from leaves. Snap off a few of the lower leaves from the plant. To do this, hold the leaf close to the base. Wiggle and twist it until it separates from the stem. Choose healthy leaves, and propagate a few at a time. Not all of them will propagate. Leave the leaves in a cool, dry place for up to a week. The cut end should end up developing a hard callous that resembles a scab. Once that happens, you can begin to sprout new roots. Fill a shallow container with soil designed for potted succulents. Lay the leaves horizontally on top of the soil. The calloused end shouldn’t touch the soil. Leave the container in indirect sunlight. Spray the top of the soil with water every day. It should be damp, but not wet. Don’t mist the soil if you live in a humid climate. In about a month, you’ll see roots growing from the cut end of the leaf toward the soil. You can lightly cover the roots with soil to prevent them from drying out. A miniature version of the plant will begin to grow upward from the cut end of the leaf. When that small plant develops its own root system and the original leaf begins to noticeably deteriorate, remove the leaf from the new plant in the same manner that you removed it from the mother plant. Be careful not to disturb the new roots. Replant the new succulent in its own pot. Use a small pot at first, and make sure to use cactus or succulent soil. [图片]Soil Succulents grow best in soil that drains well. Some types prefer nutrient-dense soil, but most do well as long as the soil isn’t too moist. Most garden stores sell soil that’s designed for cacti and succulents. If you’re growing succulents in containers, you can use a mix of equal parts sand, potting soil, and perlite. Outdoor succulents should be fed with a low-balanced fertilizer (10-10-10) in spring and late summer. Use about half the recommended ratio of fertilizer to water. Only fertilize when the soil is dry. [图片]Sunlight Nearly all succulents flourish with a lot of light. Your plants should get approximately six hours of direct sunlight every day. Depending on your planting zone and the plant type, you may need to shade your succulents during the hottest part of the day. Indoor succulents should be placed near a window. However, they shouldn’t get burned by direct sunlight. Succulents are relatively resilient when it comes to their sunlight needs. Less light may cause the colors to become dull. The plants may not bloom without sufficient UV light. However, they will survive in many lighting conditions. [图片]Where to Buy Succulents Once you start looking for succulents, you’ll notice that they’re sold in many different places. A local supplier may be able to provide you with succulents that are better for your area. Succulent plant groups can provide you with cuttings, succulent seeds or mature plants. Local botanical gardens may also sell succulents. Many garden shops, from large chain stores to smaller local nurseries, carry succulents. However, it may be difficult to find rare or unusual species here. Succulents sold in garden shops are often already potted. Some of the most beautiful, unique and vibrant succulents are difficult to find locally. Thank goodness for the internet. Many online vendors will ship these plants directly to you. You can choose the specific variety that you purchase. You can also often get a discount if you buy large sets of mixed varieties. Buying succulents in bulk online may be preferable if you’re trying to fill up a vertical garden or a large space. The plants are often sold in plugs that you can replant in the final destination. Succulents are not expensive. You can get plants for anywhere from $2 to $10 on average. The price is often determined by the size and rareness of the plant. You can get them even more affordably by trading with other growers, propagating the leaves or replanting offsets. Succulents have become increasingly more popular due to their ease of maintenance and unique style. There is a wide range of succulents to choose from so you should not have any trouble finding one to match your garden or style. This succulent guide was put together to make sure you have all the information possible that you could need before you get started.

Each succulent stands out in its own way — the variegated foliage of Aeonium, the size and grandeur of Agave, the cold-hardiness and resilience of Sempervivum. Out-of-this-world color and year-round beauty belong to Echeveria. [图片]Hailing from semi desert regions of Mexico and of Central and South America, Echeveria thrives in the mild climates of California and the American Southwest. Its colorful, glaucous foliage and year-after-year flowering makes it one of the most popular succulent types. Cold sensitivity may be a concern for many gardeners, but conveniently enough, Echeveria makes a great container plant. Once fall rolls in, just pack up and bring it indoors. Welcome your containers back into the garden in spring. [图片]Where it will grow: Hardy to around 32 degrees Fahrenheit (0 degrees Celsius), depending on species (USDA zones 9a to 11b). Water requirement: Looks best with moderate water. Light requirement: Full sun, but shelter it from harsh summer sun. Mature size: Varies with species. Benefits and tolerances: Drought tolerant; deer resistant. Seasonal interest: Evergreen; flowers in summer. When to plant: Plant cuttings or offsets spring through fall; allow the stem end to become callous. [图片]Distinguishing Traits Echeveria is rosette forming, with fleshy green leaves in colors ranging from green to gray-green to purple, with colored tips and other quirky accents augmenting its playful demeanor. The color remains strong year-round, and even in the dark grays of winter, your garden will receive a nice pink foliage pick-me-up. Unlike many succulents, Echeverias are not monocarpic and can flower several times throughout a lifetime. In summer look for a stem of clustered flowers, often in bright pinks and yellows. [图片]How to Use It Plant Echeveria en masse, as a container specimen or along a rocky bank. Depending on your climate zone and style preference, the options are pretty open. Echeverias are commonly planted in containers. Their portability makes summer and winter maintenance that much easier. If summer climates are more extreme, shelter plants from direct sunlight. Likewise, bring your Echeveria indoors if your climate experiences freezing winters. Be sure to provide ample direct light. Echeverias are also used in living walls for sunny locations. [图片]Planting Notes Echeverias look healthiest and develop the best year-round color when planted in full, coastal sun. Some Echeverias develop tall stalks, and eventually you may want to cut and reroot the rosette, much like is done with Aeonium. Leave the stalk and new Echeverias will sprout. Others produce offsets, which can also be used to propagate. Try to avoid extreme light and temperature swings while providing good air circulation and good light. Give it some water but not too much, and otherwise let it do its thing.

Maihuenia is a genus largely accepted as containing two species which are quite distinct from other cactus. The plants in this genus are so different that they have been classified as the sole genus in the subfamily Maihuenioideae. [图片]These plants grow as mats which hug the ground and are made up of segmented short-rounded stems. The stems feature typically 3 spines per areole and also have small rounded leaves which do not fall off as they do in Opuntias. The flowers come from the ends of the stems and are shades of yellow from near-white to orange. Club-shaped fruits are fleshy and contain bracts. The natural habitat of this species is in the region known as Patagonia in the southern parts of Argentina and Chile at elevations of 8,000 feet (2450 m) elevation. In this harsh environment, these cacti commonly endure frost and are starting to become sought by cold-hardy cactus growers in North America. [图片]Growing Condition and General Care Maihuenia is an easy-to-grow plant. It can survive outside in the garden in the sunny rockery on a sheltered place, but only if it’s protected with a sheet of glass during the wintertime. It is also very good for a large pot which can be stored inside an unheated greenhouse or on a balcony, somewhat protected from moisture during the winter, but is probably safest to grow it in the Alpine House or in a raised bed inside an unheated greenhouse all year around, with lots of ventilation. They should not be kept hot in summer as they are from high elevations. During the growing season it’s good to enrich the soil using a fertilizer rich in potassium and phosphorous, but poor in nitrogen. For a balanced development, it is best to place it in a position where it is exposed at least a few hours of direct sunlight. Water these plants only from time to time if grown outdoors, but it should be watered abundantly if grown in a pot or in the greenhouse, during the summer.[图片]The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favor the development of fungus diseases, which should be treated with a systemic fungicide. Repot it every 2 to 3 years.
