Plants That Start With H
Here is your complete reference for popular and useful plants beginning with the letter H. Each entry includes growing tips and ideal uses. Use this list to plan your next trip to the nursery or to identify plants you have seen in your neighborhood.
Hardy Hibiscus
Hardy hibiscus (Hibiscus moscheutos) brings a tropical look to northern gardens. The flowers can reach dinner-plate size, sometimes 10-12 inches across. They bloom in late summer with colors ranging from deep red to pink and white.
These plants die back to the ground each winter in cold climates. They grow fast in spring, so be patient. Plant them in full sun and moist soil for the best flower production. They are heavy feeders, so add compost yearly.
- Height: 3-7 feet tall
- Bloom time: Mid-summer to fall
- Light: Full sun
- Hardiness zones: 4-9
Heuchera (Coral Bells)
Heuchera is a staple for shade gardens, prized for its colorful foliage. The leaves come in shades of purple, lime green, caramel, and silver. They form neat mounds that look great edging a path or filling a container.
While they do send up small flower spikes in late spring, the foliage is the main attraction. These plants are low-maintenance and deer-resistant. They prefer well-drained soil and partial shade, though some varieties handle more sun.
- Choose a spot with morning sun and afternoon shade.
- Dig a hole twice as wide as the root ball.
- Set the crown at soil level, not deeper.
- Water regularly until established.
Hosta
Hosta is the go-to plant for shady areas where little else grows. They come in a huge range of sizes, from tiny miniatures to giant specimens with leaves over a foot long. Foliage colors include blue, green, gold, and variegated patterns.
These are tough, long-lived perennials that need very little care. The main pest is slugs, which chew holes in the leaves. To prevent damage, keep the area clean and consider using a slug bait in early spring.
Hostas also produce lovely lavender or white flowers in summer. Some gardeners cut the scapes off to keep the focus on the leaves. Others enjoy the extra color and fragrance.
Hydrangea
Hydrangeas are among the most popular flowering shrubs. The big, showy flower clusters last for weeks in summer and can be dried for indoor arrangements. There are several types, each with different pruning needs.
Bigleaf hydrangeas (Hydrangea macrophylla) bloom blue in acidic soil and pink in alkaline soil. Panicle hydrangeas (Hydrangea paniculata) have cone-shaped flowers and are more sun-tolerant. Smooth hydrangeas (Hydrangea arborescens) include the classic ‘Annabelle’ variety.
When planting, dig a hole that is shallow but wide. Water deeply once a week during dry periods. Mulch around the base to keep roots cool and moist.
Heather
Heather (Calluna vulgaris) is a low-growing evergreen shrub that thrives in poor, acidic soil. It produces masses of small bell-shaped flowers in late summer and fall. The foliage also changes color with the seasons, adding year-round interest.
Heather requires excellent drainage and full sun. It does not like heavy clay or wet feet. If you have sandy or rocky soil, this plant will be very happy. It is a great choice for slopes and rock gardens.
Prune lightly in early spring to keep the plants compact. Do not cut back into old wood, as it may not regrow. A yearly trim keeps the plant looking tidy and encourages new growth.
Hellebore
Hellebores are the stars of the late winter garden. They bloom when little else is showing color, often pushing through snow. The nodding flowers come in shades of white, pink, purple, and green, and some are speckled or double.
These plants prefer partial to full shade and rich, well-drained soil. They are deer-resistant and long-lived. Once established, they are quite drought-tolerant. Remove old leaves in late winter to show off the new flowers.
Hellebores self-seed readily. You may find seedlings popping up around the parent plant. You can transplant them to other areas or share them with friends. They take a few years to reach blooming size.
Honeysuckle
Honeysuckle vines are vigorous climbers with fragrant, tubular flowers. They attract hummingbirds and butterflies. Some varieties are evergreen in mild climates, while others are deciduous.
Plant honeysuckle near a trellis, fence, or arbor. Provide full sun to partial shade. The soil should be well-drained but not too rich. Once established, these vines are quite tough and need little attention.
Be aware that some types, like Japanese honeysuckle, are invasive in certain regions. Check with your local extension office before planting. Native varieties are a safer choice for the environment.
Hyssop
Hyssop (Agastache) is a fragrant perennial that belongs to the mint family. It has spikes of tubular flowers in blue, purple, pink, or orange. The foliage smells like licorice or anise, depending on the variety.
This plant is a magnet for bees and hummingbirds. It thrives in full sun and well-drained soil. It does not like wet conditions, especially in winter. Plant it in a spot with good air circulation.
Hyssop is also an edible herb. The leaves can be used fresh or dried in teas and salads. The flowers make a colorful garnish. It is a great addition to a pollinator garden or herb bed.
Heavenly Bamboo
Heavenly bamboo (Nandina domestica) is not a true bamboo, but it has a similar upright, cane-like growth habit. It is an evergreen shrub with delicate, lacy foliage. The leaves turn red and purple in cool weather.
It produces clusters of white flowers in spring, followed by bright red berries in fall. The berries persist through winter, providing food for birds. This plant is adaptable to sun or shade and a range of soil types.
Heavenly bamboo is low-maintenance and pest-free. It can be used as a foundation plant, in a border, or as a specimen. Some dwarf varieties stay under 2 feet tall, perfect for small spaces.
Hollyhock
Hollyhocks are old-fashioned cottage garden plants with tall spikes of large, showy flowers. They can reach 6-8 feet tall. The flowers come in single or double forms in a wide range of colors, including yellow, red, pink, and nearly black.
These are short-lived perennials, but they self-seed freely. Plant them at the back of a border or against a wall for support. They prefer full sun and well-drained soil.
Hollyhocks are prone to rust, a fungal disease that causes orange spots on the leaves. To reduce problems, water at the base and provide good air circulation. Remove infected leaves promptly.
Hyacinth
Hyacinths are spring-blooming bulbs with intensely fragrant flower clusters. They come in shades of blue, purple, pink, white, and yellow. The flowers are dense and spiky, making them excellent for cut arrangements.
Plant the bulbs in fall, about 4-6 inches deep and 6 inches apart. Choose a spot with full sun and well-drained soil. After blooming, let the foliage die back naturally to feed the bulb for next year.
Hyacinths also work well for forcing indoors. Plant them in a vase or pot with the bulb base just touching the water. Keep them in a cool, dark place for several weeks until roots form, then move to a sunny window.
Edible Plants Starting With H
Beyond ornamentals, there are several useful edible plants that begin with the letter H. These can add fresh flavors to your kitchen and garden. Here are a few to consider.
Horseradish
Horseradish is a hardy perennial grown for its pungent root. It is easy to grow and can be quite vigorous. Once planted, it is difficult to remove, so choose a spot where it can stay.
Plant root cuttings in early spring in full sun. The soil should be loose and fertile. Harvest the roots in fall after a frost, which improves the flavor. Grate the root fresh for a spicy condiment.
Huckleberry
Huckleberries are small, wild berries similar to blueberries. They grow on low shrubs in acidic, well-drained soil. They prefer partial shade and cool, moist conditions.
These plants are not commonly sold in nurseries, but you can find them in the wild. They are difficult to cultivate. If you have the right conditions, you can try transplanting a small plant from a friend’s property.
The berries are delicious fresh or in jams and pies. They are rich in antioxidants. Birds love them too, so you may need to protect the fruit with netting.
Habanero Pepper
Habanero peppers are one of the hottest chili peppers you can grow. They have a fruity, smoky flavor that is prized in hot sauces and salsas. The plants are productive and ornamental, with small, lantern-shaped fruits.
Start seeds indoors 8-10 weeks before the last frost. They need warm soil to germinate. Transplant outdoors after all danger of frost has passed. Provide full sun and rich, well-drained soil.
Harvest the peppers when they turn orange or red. The heat level increases as they mature. Use gloves when handling them, as the oils can burn your skin.
More H Plants For Specific Conditions
Depending on your garden’s unique conditions, you might need a plant that tolerates shade, drought, or wet soil. Here are some more options that start with H.
Hakone Grass
Hakone grass (Hakonechloa macra) is a graceful, arching ornamental grass. It forms a low, cascading mound of bright green or gold foliage. It is one of the best grasses for shade.
This plant thrives in moist, well-drained soil and partial shade. It does not like hot, dry conditions. It is slow to establish but well worth the wait. It looks stunning spilling over a path or wall.
Hardy Geranium
Hardy geraniums, or cranesbills, are tough, long-blooming perennials. They are different from the tender pelargoniums often sold in pots. They come in many colors and sizes, from groundcovers to upright clumps.
Most prefer full sun to partial shade and well-drained soil. They are very adaptable and easy to grow. Many varieties rebloom if you cut them back after the first flush of flowers.
Hawkweed
Hawkweed is a low-growing wildflower with bright orange or yellow daisy-like flowers. It is often considered a weed in lawns, but it can be a charming addition to a meadow or wildflower garden.
It prefers full sun and dry, sandy soil. It spreads by runners and can be aggressive. If you want to control it, plant it in a contained area or in a pot sunk into the ground.
Horned Violet
Horned violets (Viola cornuta) are small, delicate perennials with pansy-like flowers. They bloom in spring and often again in fall. They come in shades of purple, blue, yellow, and white.
They prefer cool weather and partial shade. They are great for edging, containers, and rock gardens. They self-seed gently and will naturalize in a woodland setting.
How To Choose The Right H Plant
With so many options, picking the right plant can feel overwhelming. Start by assessing your garden conditions. Check the amount of sunlight, soil type, and moisture levels. This will narrow down your choices significantly.
- Measure the sunlight in the area for a full day.
- Test the soil drainage by digging a hole and filling it with water.
- Note the hardiness zone for your region.
- Consider the mature size of the plant.
- Think about the bloom time and season of interest.
Match the plant to the site, not the other way around. A plant that gets the right conditions will be healthier and need less care. Do not try to force a sun-loving plant into a shady corner.
Common Mistakes To Avoid
Even experienced gardeners make mistakes. Here are some common pitfalls when growing H plants. Avoid these to save yourself time and frustration.
- Planting hydrangeas too deep, which prevents blooming.
- Overwatering heuchera, leading to root rot.
- Pruning bigleaf hydrangeas at the wrong time, cutting off next year’s flowers.
- Letting hostas dry out completely in hot weather.
- Planting invasive honeysuckle without checking local regulations.
Take the time to research each plant’s specific needs. A little preparation goes a long way. Your plants will reward you with vigorous growth and beautiful flowers.
