Bee balm, (Monarda didyma) also know commonly as Oswego tea, monarda, bergamot, or horsemint is an all-purpose flowering perennial that grows almost anywhere with little to no care. In fact, monarda is so eager to become established that it out competes many other plants. There are, however, many species that can partner well with bee balm and provide a frenzy of garden blooms throughout most of the summer into fall.
Phlox A good companion for bee balm is summer phlox (Phlox paniculata). Sharing the colors and hues of bee balm it provides a sturdy mostly care-free floral display that compares favorably with monarda. While both are prone to mildew, they benefit from similar prevention strategies such as reduced summer fertilization. Both species like the same garden condition of full sun, regular water, but no overhead irrigation. The two species grow to about the same height and can be used as specimens as well as planted in massings and drifts. Eupatorium Because bee balm tolerates a wide range of garden conditions and is aggressive enough to hold its own against all comers, planting it with Joe Pye weed (Eupatorium maculatum) makes for a great combination. Bee balm can readily partner with the much taller Joe Pye weed and both are butterfly magnets in the hot summer sun. Both are appropriate choices for rain gardens as they grow well in moist soils and can tolerate occasional wet "feet." Moreover as an added bonus, neither species suffers from any major insect problem. Rudbeckia The yellow summer flowers of the black-eyed Susans (Rudbeckia hirta) offer a striking contrast to the similar-sized pink-to-red and purple bee-balm. The daisylike flowers of the rudbeckias are contrasted with the clustered flowers of the monarda providing interest beyond color in the summer garden. The spreading nature of both plants in some situations can lead to a healthy competition of over-eager contenders for the title of garden bully as both species are somewhat invasive and vie for attention and space.
Echinacea If the summer garden plan calls for soft pastels and look for a daisy shape to complement the bee balm then purple cone flowers (Echinacea purpurea) are just the thing. Though the common name includes "purple," cone flowers come in a dizzying wide array of colors from white through tangerines to deep purples. Through the years cone flowers may need some help fending off the vigorous growth of the bee balms.

Black-eyed susans (Rudbeckia hirta) grow as biennials or short-lived perennials. They break dormancy the first year and flower the next. You can sow the seeds outdoors in fall or spring, but they still require some fall preparation for a spring planting. Black-eyed Susans grow in U.S. Department of Agriculture plant hardiness zones 3 through 7, where they perform much like perennials because they readily self-sow. Fall Sowing
Black-eyed Susans sprout in the spring if you plant them in fall in climates that experience at least three months of temperatures below 40 degrees Fahrenheit. Plant the seeds in early to midfall, about six weeks before the first expected frost. Work a 2-inch-thick layer of compost into the top 8 inches of a well-drained garden bed that receives full summer sun. The plants grow in average soil conditions, so fertilizer amendments aren't necessary. Sow approximately six seeds per square foot and cover them with a 1/4- to 1/2-inch layer of soil. Not all seeds germinate the first year, which is why you need to sow so thickly. Spring Planting
Seeds sown in spring require pretreatment if you want flowers the first year. Keep the seeds in a place where it's 40 F or cooler, either outdoors or in the refrigerator, for three months before planting to help the seeds break dormancy. Plant the seeds 1/4-inch deep in the prepared garden bed in spring, after the last frost date. Space the seeds 4 to 6 inches apart in all directions and thin them to the appropriate spacing after they germinate. Indoor Planting
Indoor-sown black-eyed Susans still require cold treatment to germinate. Pot the seeds in cell packs or 2-inch seedling pots in fall, sowing one or two seeds per container. Use a moistened, sterile seed-starting media to minimize fungal growth. After potting, place the containers in a sealed bag to retain moisture and place the pots outdoors or in the fridge to maintain the 40 F temperature. Take the pots out of cold storage four to six weeks before the last frost date. Provide them with all-day sun and water when the soil surface feels dry. The seedlings should be about 6 inches tall and ready for outdoor transplant by the last expected frost in spring. Plant the seedlings at the same depth they are at in the pot, spacing them 12 inches apart in the garden bed. Early Care
Moderately moist soil helps ensure germination and healthy seedling growth. Water the bed beginning in spring as needed so the top 6 inches of soil stay moist. Direct-sown seeds will require thinning after they sprout. Pinch off the extra seedlings at ground level once the plants begin growing in their second or third set of leaves. Black-eyed Susan plants grow to a 12 inch spread, so leave about 12 inches between plants. Slugs can destroy the seedlings. Set slug traps around the garden or hand pick the pests from the bed after dark. Once established, black-eyed Susans require little care and rarely suffer from pest problems.

There are approximately 300 species of dianthus to choose from, in biennial, annual and perennial varieties. They have colorful blooms in numerous shades of pink, white, red and purple. The blooms open in spring and will last until frost, if provided with the right growing conditions and care. Dianthus are not fussy plants and it takes very little to keep them happy. Plentiful sunlight, sufficient water and regular grooming help ensure that blooms adorn the plants all season long.
Step 1 Plant dianthus in a site that receives full sun at least six hours every day. Step 2 Place 2 inches of mulch around the plants to keep moisture from evaporating too quickly. Step 3 Water dianthus when less than 1 inch of rain falls in a week. Step 4 Feed every month during the growing season with water-soluble fertilizer. Step 5 Clip the blooms off as they fade. Step 6 Broadcast a 1-inch layer of compost around the plants each spring if growing perennial or biennial dianthus.
Step 7 Divide perennial dianthus clumps once every three or four years. This is best done in early spring.

Varieged ginger (Alpinia zerumbet) is a dramatic, upright plant with long, sword-shaped leaves variegated in shades of yellow and green. Fragrant pink and white flowers adorn the plant throughout much of the year. Variegated ginger, which grows from underground rhizomes that look much like ginger root, is propagated by dividing the rhizomes of mature plants. A warm-climate plant, variegated ginger is suitable for planting in U.S. Department of Agriculture hardiness zones 9 to 11.
Growing Requirements Variegated ginger is a versatile plant that tolerates a range of growing conditions from full shade to full sun, but the plant is happiest in partial shade and benefits from protection during the hot part of the afternoon. The plant tolerates nearly any well-drained soil, but prefers rich organic soil. Propagation by Division To divide variegated shell ginger, use a shovel or garden fork to dig an entire clump. Alternatively, if the clump is very large, use a shovel to dig a section of the plant's outer edge. Lift the clump from the ground, then pull the rhizomes apart. Plant the rhizomes with the shoots attached, or remove the shoots and plant the rhizomes. Planting Divisions Plant divided ginger in soil that you have prepared ahead of time. Variegated ginger likes fertile soil and benefits from the addition of 2 to 4 inches of organic matter such as leaf mold, compost or decomposed manure. Plant the rhizomes, or the rhizomes with shoots attached, at the same soil depth the rhizomes were located in their original planting spot. Cover the rhizomes with soil, then pat the soil firmly over the rhizomes. Water the area immediately after planting.
General Care Variegated ginger is moderately drought tolerant, but does best in soil kept consistently moist. Regular watering is especially critical during periods of hot, dry weather, or if the plant is located in full sunlight. Water often enough to keep the soil moist but not soggy. Fertilize variegated ginger every other month, using a balanced, dry fertilizer. Apply fertilizer in accordance with the specifications provided on the label.

Although sedums are hardy plants that grow in even harsh conditions with little care, they often become floppy and collapse in the center. Floppiness is especially a problem with tall sedum varieties such as "Autumn Joy," "Black Jack" and "Autumn Fire. A few minutes of routine maintenance keeps sedums bushy and upright.
Causes Floppiness is normal for tall sedum varieties that aren't routinely pruned; the plant eventually becomes top heavy and collapses under the weight of the blooms. Lack of sunlight and too much fertility in the soil are also common causes of floppiness and caving in at the center of the plant. Sedum is a warm-weather succulent plant that thrives in full sunlight and average or poor soil. Some sedum varieties are tough enough to thrive in dry, gravelly soil. Pinching Pinching is a simple method of promoting compact, sturdy, bushy growth on new sedum plants. Pinch the growing tips of young plants when they are about 6 to 8 inches tall. Pinching causes a slight delay in blooming, but the result will be more blooms and healthier plants. Pruning While it seems extreme, a good pruning is the best solution for a tall, lanky sedum. If your plants are beginning to look tipsy in late spring or early summer, use your garden shears or clippers to cut the plants to a height of about 6 to 8 inches. The plants may initially look like victims of a bad haircut, but they will soon rebound and look better than ever. Pruning can safely be done every year if needed and is especially effective for sedums grown in shade. Division Division is the best fix for an older sedum, especially if the center of the plant looks like it's dying down and becoming woody and unattractive. To divide sedum, dig up the entire plant. Pull the plant apart into smaller plants, each with several healthy roots. If a plant is too large to dig, use a trowel or shovel to cut a section from the side of the plant. Division is a good opportunity to move the sedum to a spot in full sunlight and to discard old, woody sections. To keep sedum healthy, get in the habit of routinely dividing the plant every other year.
Tips Water sedum sparingly; wet soil may cause sedum to rot and die. In most parts of the country, sedum thrives with no supplemental irrigation but benefits from an occasional light watering during long periods of hot, dry weather. Don't fertilize sedum; fertilizer contributes to rich soil, which can cause floppiness and weak growth.

The bright shades of phlox are a welcome sight in the garden after a long winter. Whether it's the first sign of spring creeping phlox or the tall plants of summer, there is a phlox that fits every garden and provides colorful blooms almost all season long. Good for cut flowers, tall garden phlox also attract butterflies and hummingbirds.
Bloom Time A common spring sight, creeping phlox produces a dense, low-growing mat of color. Blooming from April through to June, creeping phlox is available in a wide assortment of colors including pink, white, mauve, red, blue and purple and makes a striking statement along garden edges. Garden phlox grow to 4 feet of brilliant color and bloom July through to mid-September. A low-maintenance plant, garden phlox is available in bright shades of magenta, white, pink, red and blue. Planting All phlox prefer full sun, but will perform well in partial shade. Plant in moist, well-drained soil that has been amended with a few inches of compost. Garden phlox can mature to 2 feet in width at its base, so when planting, give them plenty of room to spread. Dig a hole comparable in size to the container the plant was grown in and ensure the top of the root ball is level with the soil surface when planted. Fill in the hole, water the plant well and add a layer of mulch to help maintain moisture and deter weeds. All phlox are hardy to U.S. Department of Agriculture plant hardiness zone 4. Care Add a layer of compost and mulch each spring to continue to deter weeds and keep the soil moist. Deadhead the faded flowers on garden phlox to promote new and continued blooms and prevent reseeding. Divide the plants every three years and in the fall after the first heavy frost cut tall garden phlox back to 2 inches above the base of the plant. Powdery mildew is a common affliction of phlox, and dividing regularly and providing added air circulation can help reduce the severity of the disease. Powdery mildew will not harm the plant, but it does cause the leaves and stems to develop a grayish white coating, which may turn yellow, and fall off the plant. As a result, mildew-resistant cultivars are becoming available at garden centers.
Phlox History It was John Bartram in the 1740s who introduced phlox to England where it was then grown in many estate gardens. It became a garden staple in the 1850s as people found more leisure time and gardening became popular with many home owners. In 1837 alternative varieties of phlox began to emerge, and garden phlox remained popular until the 1930s when annuals took over as the garden plant of choice. It wasn't until the 1990s that perennials bounced back onto the gardening scene and the phlox has remained a common site in many perennials gardens ever since.

Boston fern, known botanically as Nephrolepis exaltata "Bostoniensis" is a tropical fern commonly grown as a patio, porch or indoor plant. According to the University of Rhode Island, "Bostoniensis" is a cultivar that demands high ambient humidity and consistently moist soil. Watering the soil is but one way that you will need to deliver moisture to your plant to keep it healthy. To prevent your fern from suffering browning leaf tips or frond die-back, vigilant care is needed, and the higher you can get the humidity around your Boston fern, the happier it will be.
Step 1 Water the soil of your Boston fern consistently to keep it evenly very moist to the touch but not drowning in stagnant water. Unlike some ferns, Boston fern cannot tolerate its soil to be dry, even on the surface, between waterings. In hot and dry climes, daily watering may be required, while gardeners in cool, rainy climes can offer less frequent irrigation. Step 2 Boost the ambient humidity passively by setting the fern pot atop a shallow tray filled with stones or marbles and water. Keep the bottom of the pot above the water resting on the stones but refill the tray reservoir frequently to keep the water level high.
Step 3 Mist your Boston fern frequently with a spray bottle filled with distilled water. In low humidity environs or when heating and cooling is being used, daily misting may help keep the fronds green. Refrain from misting with tap water as the treatment chemicals, salts and minerals in the water can damage the leaves.

Perennials live for at least three years, although some survive for much longer. Many perennial species die back to the ground in winter and regrow in the spring. To identify purple perennials, note their foliage, form and flower type. Purple perennials add deep to bright color to the landscape, and some species attract pollinating wildlife, such as hummingbirds, butterflies or bees, with their nectar. Plant species that bloom at different times during the growing season for constant color. Early Bloomers
Early blooming perennials start producing flowers in spring, which lasts from March through May. Purple-flowering species include the bugle weed (Ajuga reptans), a 6- to 9-inch-tall perennial that spreads as a ground cover. Bugle weed blooms with small, purple, blue and white flowers that stand on inflorescences. Flowers have a forked lower petal and attract bees. Turkish veronica (Veronica liwanensis) blooms in late spring with purple to blue flowers on tall racemes. The small blossoms grow from the bottom to the top. Turkish veronica grows to 2 feet tall and has lustrous, evergreen leaves. This perennial can be grown as a spreading ground cover. Summer Bloomers
The summer blooming season begins in June and lasts through August. The purple coneflower (Echinacea purpurea) produces purple, pink and white daisylike blooms with dark gold centers in summer. The conflower's long-lasting blossoms grow from 2 1/2 to 5 inches in diameter and have 12 to 20 drooping petals. Purple coneflowers have rough leaves, hairy stems and grow from 1 to 3 feet tall. Lavender (Lavandula angustifolia ) blooms through the summer months with fragrant spikes of small, pale to deep purple blossoms. Lavender has aromatic, gray-green foliage and grows from 2 to 3 feet tall. It grows in upright clumps and has stippled leaves that turn silvery in winter. Late Summer to Fall Bloomers
Late-blooming purple perennials produce flowers from August until September, though sometimes blossoms last until the first killing frost. Catmint (Nepeta spp.) blooms in late summer with tall spikes of violet to blue flowers. This relative of the catnip plant has fragrant flowers and foliage and grows from 12 to 36 inches tall. Russian sage (Perovskia atriplicifolia) flowers from July through October. This aromatic perennial produces tall spikes of purple-blue flowers and grows in an upright form. Russian sage grows from 36 to 60 inches tall and has gray-green, fragrant foliage. Season-Long Bloomers
Some purple perennials bloom for much of the growing season. These include the creeping heliotrope (Heliotropium amplexicaule), which flowers from summer through fall. This spreading plant produces clusters of tiny, tublular, blue to purple blossoms and grows from 6 to 12 inches tall. Bergamot (Monarda hybrids) bloom all summer long with purple, red or pink flowers. This perennial's flowers have spiky, thin petals and upright stamens. Bergamot grows from 2 to 4 feet tall and attracts bees, hummingbirds and butterflies.

Black-eyed Susans (Rudbeckia) add a dramatic swash of color to summer garden beds, borders and planters. Most varieties have bright yellow blossoms, but red and purple varieties are also available. The upturned flowers have a central black seed cone that earns the plants their name. Seed production prevents the plants from producing a second set of blooms later in the season. Cutting back the black-eyed Susans can reward you with blooms throughout the growing season.
Step 1 Trim back the flower stems in summer after the blossoms begin to wilt. Cut the stems off ¼ inch above the topmost leaf. Plants that are cut back may flower a second time in the fall. Step 2 Cut back the the entire black-eyed Susan plant after the first fall frost kills off any remaining flowers. Prune the stems down to just above the top healthy leaves. Cut off any dead or browned leaves.
Step 3 Spread a 2- to 4-inch layer of mulch over the black-eyed Susan bed once the ground begins to freeze, typically after three to four fall frosts have occurred. Mulch protects the crown of the trimmed flowers and helps them survive winter.

Sago palms (Cycas revoluta) are desirable tropical plants that grow outdoors in climates that receive no frost and as houseplants and bonsai specimens in cooler regions. Although they are not true palms and are more closely related to pine trees, sago palms look like palms and serve as interesting landscape plants. The 250 species of plants in the Cycad plant family are some of the most ancient seed-producing plant species. When the sago palm reproduces, it forms young plants, called offshoots or "pups" at its base.
Step 1 Harvest pups in late winter or early spring when plants are in their dormant phase. If your mature sago palm has begun to produce new leaves, wait until the following winter before you cut away any young plants from the base. Step 2 Snap off small pups with your gloved hands if possible. If a pup fails to break off the main plant easily, use a knife or trowel to cut it, taking care not to injure the mother plant. Use a sharp shooter shovel to remove large pups. Step 3 Snip off all existing leaves from pups after you separate them from the mother plant. Also snip off any existing roots. Step 4 Rinse off all soil from pups by placing them in a tub of water. Use a soft brush to remove all foreign matter. Step 5 Place cleaned, stripped pups in a cool, dry place for one week to allow the area where you cut it from the mother plant to dry. Pups will survive several months in a cool, dry place.
Step 6 Make a potting mix from perlite, peat moss and coarse river sand. Plant pups in pots with drainage holes that are only slightly larger than their diameter. Leave the top half of each pup above the soil surface, then water until water runs from the drainage hole(s). Allow the soil to dry before you water your pup again. Keep potted pups in a warm, well-lighted area.
