Flowering Plants Starting With K
This category features plants prized primarily for their blooms. They can range from delicate indoor flowers to bold garden statements.
Kalanchoe Blossfeldiana
Often sold as a flowering gift plant, Kalanchoe is a durable succulent. It’s known for its long-lasting clusters of small flowers in red, pink, yellow, or white.
Care Instructions For Kalanchoe
To keep your Kalanchoe healthy and encourage re-blooming, follow these steps.
- Provide bright, indirect light. Some direct morning sun is beneficial.
- Water thoroughly only when the soil is completely dry. Overwatering causes root rot.
- Use a well-draining cactus or succulent potting mix.
- After flowering, prune spent blooms and provide 14 hours of darkness daily for 6 weeks to trigger new buds.
Kangaroo Paw (Anigozanthos)
This Australian native is instantly recognizable. Its tubular, fuzzy flowers truly resemble an animal’s paw and come in striking colors like red, yellow, green, and black.
Growing Kangaroo Paw Successfully
These plants require specific conditions to thrive outside their native habitat.
- They need full sun and excellent drainage. Raised beds are often ideal.
- Water moderately, but allow the soil to dry between waterings. They are drought-tolerant once established.
- In colder climates, they can be grown as annuals or in containers brought indoors for winter.
- Avoid wetting the foliage, as this can lead to fungal leaf spot.
Kniphofia (Red Hot Poker)
This perennial makes a dramatic vertical statement in the garden. It produces tall spikes of tubular flowers that typically graduate from red or orange at the top to yellow at the base.
It’s a favorite for attracting hummingbirds and butterflies. The grassy foliage forms a large clump over time.
Edible Plants Starting With K
From common vegetables to exotic fruits, this group provides tasty and nutritious options for your kitchen garden.
Kale (Brassica Oleracea Var. Acephala)
Kale is a powerhouse of vitamins and minerals. It’s extremely cold-hardy, often tasting sweeter after a frost.
How To Grow Kale
- Plant in full sun to partial shade in cool weather (spring or fall).
- Space plants about 12 to 18 inches apart in rich, well-drained soil.
- Keep soil consistently moist for tender leaves.
- Harvest outer leaves regularly to encourage new growth from the center.
Kohlrabi (Brassica Oleracea Var. Gongylodes)
Kohlrabi grows a bulbous stem above ground that tastes like a sweet, mild broccoli stem. You can eat it raw or cooked.
It’s a fast-growing cool-season crop. For the best flavor, harvest when the bulb is about 2 to 3 inches in diameter, before it becomes woody.
Kiwi Fruit (Actinidia Spp.)
The fuzzy kiwi (Actinidia deliciosa) is the common grocery store fruit. Hardy kiwi (Actinidia arguta) produces smaller, smooth-skinned fruits that can be eaten whole.
Essential Tips For Kiwi Vines
- Most kiwi plants are dioecious, meaning you need both a male and a female vine for fruiting.
- They require strong support like a sturdy pergola or trellis, as vines can grow very large.
- Plant in full sun with protection from strong winds.
- Provide consistent watering, especially during fruit development.
Kumquat (Fortunella Spp.)
Kumquats are unique citrus where the sweet rind is eaten along with the tart inner flesh. They are often grown in containers in cooler climates.
They are more cold-tolerant than many citrus trees. Kumquats make excellent ornamental plants with their glossy leaves, fragrant flowers, and bright orange fruit.
Trees And Shrubs Starting With K
These woody plants provide structure, shade, and year-round interest in landscapes large and small.
Katsura Tree (Cercidiphyllum Japonicum)
This is a magnificent landscape tree known for its beautiful heart-shaped leaves. In autumn, the foliage turns brilliant shades of yellow, orange, and red, and often emits a sweet, caramel-like scent.
It prefers moist, well-drained soil and can grow quite large, so give it plenty of space. It’s a relatively low-maintenance tree once established.
Korean Spice Viburnum (Viburnum Carlesii)
This deciduous shrub is cherished for its incredibly fragrant spring flowers. The pink buds open to clusters of white blossoms that perfume the entire area.
It grows into a rounded shape and also offers red to purple fall foliage. Plant it near a window or pathway where you can enjoy its scent.
Kalmia (Mountain Laurel)
Mountain Laurel is a broadleaf evergreen shrub native to eastern North America. It produces exquisite clusters of cup-shaped flowers in late spring, often with intricate patterns inside.
It thrives in acidic, well-drained soil similar to rhododendrons and azaleas. All parts of this plant are poisonous if ingested.
Indoor And Succulent Plants Starting With K
Perfect for houseplant enthusiasts, these K plants offer interesting forms and relatively easy care indoors.
Kalanchoe Tomentosa (Panda Plant)
This charming succulent has fuzzy, silvery-green leaves edged with brown or rust-colored spots. The felt-like texture is its main attraction.
It requires bright light and infrequent watering, making it ideal for forgetful gardeners. Be careful not to overwater, as the roots are prone to rot.
Kentia Palm (Howea Forsteriana)
The Kentia Palm is a classic, elegant indoor palm known for its tolerance of lower light and indoor conditions. It has graceful, arching fronds and grows slowly.
Caring For Your Kentia Palm
- Place in bright, indirect light. It can tolerate lower light but will grow slower.
- Water when the top inch of soil feels dry. Ensure the pot has good drainage.
- Wipe leaves occasionally with a damp cloth to remove dust and allow for better photosynthesis.
- Protect it from cold drafts and direct heating vents, which can brown the leaf tips.
Kalanchoe Daigremontiana (Mother Of Thousands)
This unusual succulent produces tiny plantlets along the edges of its leaves. These plantlets drop off and readily root, creating new plants—sometimes too many!
It needs bright light. Because it propagates so easily, it can become invasive in warm climates; it’s best kept in containers.
Lesser-Known And Exotic Plants Starting With K
For the adventurous gardener, these plants offer unique beauty and intriguing stories.
Kaempferia (Peacock Ginger)
This is a genus of tropical, rhizomatous perennials grown primarily for their stunning foliage. The leaves often feature striking patterns of silver, green, and purple.
They produce small but pretty flowers near the ground. In non-tropical areas, they are grown as houseplants or summer patio plants.
Kirengeshoma
Kirengeshoma is a shade-loving perennial valued for its architectural form. It has tall, upright stems with maple-like leaves and nodding, waxy yellow flowers in late summer.
It prefers cool, moist, and acidic soil in partial to full shade. It’s a subtle but sophisticated addition to a woodland garden.
Knautia
This perennial produces an abundance of small, pincushion-like flowers on long, wiry stems from summer to fall. The most common color is a rich magenta-red.
It’s excellent for cottage gardens and cutting gardens, attracting bees and butterflies. Deadheading encourages more blooms.
Practical Guide To Choosing And Caring For Your K Plants
Selecting the right plant involves more than just its name. Consider these factors to ensure success.
Assessing Your Growing Environment
Start by looking at the conditions you can provide. This is the most important step.
- Light: How many hours of direct sun does the area get? Is it bright indirect light or full shade?
- Climate Zone: Check your USDA Hardiness Zone for outdoor plants. Does the plant need to survive winter outdoors?
- Space: How much room do you have? Consider both height and spread at maturity.
- Soil Type: Is your soil sandy, clay, or loamy? Is it well-draining or tends to stay wet?
Basic Care Steps For Most Plants
While each plant has specific needs, these universal principles apply to nearly all.
- Watering: Learn the specific moisture needs of your plant. When in doubt, it’s usually safer to underwater than overwater. Always check soil moisture before watering.
- Feeding: Use an appropriate fertilizer during the active growing season. Follow label instructions to avoid over-fertilizing, which can harm roots.
- Pruning: Remove dead or diseased growth promptly. Prune for shape or size after flowering for spring bloomers, or in late winter for many trees and shrubs.
- Monitoring: Regularly check your plants for signs of pests like aphids or spider mites, or diseases like powdery mildew. Early intervention is key.
