Arkansas’s long growing season and ample rainfall make perennial vegetables a natural fit for home gardens. If you’re looking for the best perennial vegetables in Arkansas, you’ve come to the right place. These plants come back year after year, saving you time and money. They also build healthier soil and attract beneficial insects.
Perennial vegetables are the gift that keeps on giving. You plant them once, and they produce food for years. In Arkansas, with its warm summers and mild winters, many perennials thrive. You can enjoy fresh harvests from early spring through late fall.
This guide covers the top picks for your garden. We’ll talk about planting, care, and harvesting. You’ll also get tips on where to grow them in your yard. Let’s dig in and find the best options for your Arkansas garden.
Why Choose Perennial Vegetables In Arkansas
Perennial vegetables offer huge benefits for Arkansas gardeners. They require less work than annuals after they’re established. You don’t need to replant every year. This means less tilling, less watering, and less weeding over time.
Arkansas’s climate is perfect for many perennials. The state is in USDA hardiness zones 6b to 8a. Summers are hot and humid, with plenty of rain. Winters are generally mild, though some areas get freezing temperatures. Many perennials handle these conditions well.
Another big plus is soil health. Perennial roots go deep, breaking up compacted soil. They also add organic matter as they grow and die back. This improves drainage and fertility for your whole garden.
You also get earlier harvests in spring. Perennials wake up faster than annuals you’d start from seed. And they keep producing longer into the fall. Some even provide food in winter if you protect them.
Best Perennial Vegetables In Arkansas
Now let’s get to the list. These are the top performers for Arkansas gardens. Each one has specific needs, but all are worth the effort.
Asparagus
Asparagus is a classic perennial vegetable. It lives for 15 to 20 years once established. In Arkansas, it thrives in well-drained soil and full sun.
Plant asparagus crowns in early spring. Dig a trench 6 to 8 inches deep. Space crowns 12 to 18 inches apart. Cover them with 2 inches of soil at first, then add more as they grow.
Don’t harvest the first year. Let the ferns grow to build strong roots. In year two, you can harvest for 2 to 3 weeks. By year three, you can harvest for 6 to 8 weeks.
Cut spears when they’re 6 to 8 inches tall. Use a sharp knife just below the soil line. Stop harvesting when spears get thin, about the width of a pencil.
Asparagus needs consistent moisture. Water deeply during dry spells. Mulch with straw or wood chips to keep weeds down and soil cool.
Fertilize in early spring with a balanced 10-10-10 fertilizer. Also apply compost around the plants in fall. This feeds the roots for next year’s growth.
Rhubarb
Rhubarb is a tart, tangy perennial that does well in Arkansas. It prefers cooler weather, so plant it in partial shade in the south. Morning sun with afternoon shade is ideal.
Set rhubarb crowns in early spring. Space them 3 to 4 feet apart. The crown should sit just below the soil surface. Water well after planting.
Don’t harvest the first year. Let the plant establish its root system. In year two, you can take a few stalks. By year three, you can harvest freely.
Pull stalks by twisting and pulling gently. Never cut them, as this can damage the crown. Only eat the stalks—the leaves are toxic to humans and pets.
Rhubarb needs rich, well-drained soil. Add plenty of compost before planting. Mulch around the base to keep roots cool and moist.
Divide rhubarb every 4 to 5 years. Dig up the crown in early spring. Split it into sections with at least one bud each. Replant immediately.
Jerusalem Artichoke
Jerusalem artichokes, also called sunchokes, are native to North America. They produce edible tubers that taste like artichokes. They’re incredibly easy to grow in Arkansas.
Plant tubers in spring after the last frost. Space them 12 to 18 inches apart. Plant 3 to 4 inches deep in well-drained soil. Full sun is best, but they tolerate partial shade.
These plants grow 6 to 10 feet tall. They have bright yellow flowers in late summer. The flowers attract bees and butterflies.
Harvest tubers after the first frost. The cold makes them sweeter. Dig them up as needed through winter. You can leave some in the ground to regrow next year.
Jerusalem artichokes can spread aggressively. Plant them in a contained bed or use barriers. Otherwise, they might take over your garden.
They don’t need much fertilizer. A light application of compost in spring is enough. Water during dry spells, but they’re drought-tolerant once established.
Perennial Kale
Perennial kale, also called tree kale or walking stick kale, is a hardy green. It lives for 3 to 5 years in Arkansas. It produces leaves year-round in mild winters.
Plant seedlings in spring or fall. Space them 2 to 3 feet apart. They need full sun for best growth. Soil should be rich and well-drained.
Harvest outer leaves as needed. Leave the center growing point intact. The plant will keep producing new leaves from the top.
Perennial kale can grow 4 to 6 feet tall. Stake it if it gets top-heavy. Prune lower leaves to improve air circulation.
It’s very cold-tolerant. In Arkansas, it survives most winters without protection. A light frost actually sweetens the leaves.
Water regularly, especially in hot weather. Mulch to retain moisture and keep roots cool. Fertilize with compost tea or balanced fertilizer every month during the growing season.
Egyptian Walking Onion
Egyptian walking onions are a fun and productive perennial. They produce small bulbs at the top of the stem. These bulbs fall over and “walk” to new spots in the garden.
Plant bulbs in fall or early spring. Space them 6 to 8 inches apart. Plant 1 inch deep in full sun. They tolerate poor soil but prefer well-drained loam.
You can eat the green tops, the bulbs, and even the small bulblets. The flavor is stronger than regular onions. Use them fresh or in cooking.
Harvest green tops anytime. Dig up bulbs in fall or early spring. Leave some bulblets to replant themselves.
These onions are very low-maintenance. They need little water once established. They also resist most pests and diseases.
Divide clumps every 3 to 4 years. Dig them up in early spring. Separate the bulbs and replant in new spots.
Good King Henry
Good King Henry is an old-fashioned perennial green. It tastes like spinach but is more productive. It grows well in Arkansas’s climate.
Plant seeds or divisions in spring. Space plants 12 to 18 inches apart. They prefer full sun but tolerate light shade. Soil should be rich and moist.
Harvest young leaves in spring and fall. The leaves get tough in summer heat. You can also eat the flower buds like broccoli.
Good King Henry grows 2 to 3 feet tall. It has small green flowers in summer. The plant self-seeds readily, so you’ll get new plants each year.
Water during dry periods. Mulch to keep soil cool and moist. Fertilize with compost in spring and again in midsummer.
Cut back the plant after flowering. This encourages new growth for fall harvest. Divide clumps every 3 years to keep them vigorous.
Sea Kale
Sea kale is a coastal plant that adapts well to inland gardens. It produces tender shoots in spring. The flavor is like asparagus with a hint of cabbage.
Plant crowns or seeds in spring. Space them 2 to 3 feet apart. They need full sun and well-drained soil. Add lime if your soil is acidic.
Harvest shoots when they’re 6 to 8 inches tall. Cut them at the base. Stop harvesting after 4 to 6 weeks to let the plant recover.
Sea kale has large, blue-green leaves. It also produces white flowers in summer. The flowers attract pollinators.
Water regularly during dry spells. Mulch to keep roots cool. Fertilize with compost in spring.
Protect plants from slugs and snails. Use beer traps or diatomaceous earth. Sea kale is generally pest-free otherwise.
Perennial Broccoli
Perennial broccoli, also called nine-star broccoli, produces small heads year after year. It’s a cross between broccoli and kale. It grows well in Arkansas’s mild winters.
Plant seedlings in spring or fall. Space them 2 to 3 feet apart. They need full sun and rich soil. Add compost before planting.
Harvest the central head first. Then pick side shoots as they develop. The plant produces for several months in spring and fall.
Perennial broccoli lives 3 to 5 years. It goes dormant in summer heat. Cut it back in late summer for a fall crop.
Water deeply during dry spells. Mulch to retain moisture. Fertilize with a balanced fertilizer every 4 to 6 weeks.
Watch for cabbage worms and aphids. Use row covers or insecticidal soap. Keep the area clean to reduce pests.
Horseradish
Horseradish is a spicy root that’s easy to grow in Arkansas. It’s very hardy and can become invasive. Plant it in a contained bed or use barriers.
Plant root cuttings in early spring. Space them 18 to 24 inches apart. Plant 2 to 3 inches deep in full sun. They tolerate partial shade but produce less.
Harvest roots in fall after the first frost. Dig up the largest roots. Leave smaller ones to regrow next year.
Grate the roots fresh for the best flavor. Store unused roots in the refrigerator or freezer. They keep for months.
Horseradish needs consistent moisture. Water during dry spells. Fertilize with compost in spring.
Divide plants every 2 to 3 years. Dig up the entire clump. Replant only the best roots. This keeps the plants productive.
Perennial Spinach
Perennial spinach, also called New Zealand spinach, is a heat-tolerant green. It’s not true spinach but tastes similar. It thrives in Arkansas’s hot summers.
Plant seeds in spring after the last frost. Soak seeds overnight before planting. Space plants 12 to 18 inches apart. They need full sun to partial shade.
Harvest young leaves and tender tips. Pick regularly to encourage new growth. The plant produces from spring until frost.
Perennial spinach grows as a spreading ground cover. It can reach 2 feet tall and 3 feet wide. Use it as a living mulch in your garden.
Water regularly, especially in hot weather. Mulch to keep soil cool. Fertilize with compost tea every few weeks.
It’s very pest-resistant. Deer and rabbits usually leave it alone. It also tolerates poor soil and drought once established.
How To Plant And Care For Perennial Vegetables
Planting perennials takes a bit more planning than annuals. But the payoff is huge. Here’s a step-by-step guide for Arkansas gardens.
Site Preparation
Choose a spot with full sun for most perennials. Some tolerate partial shade. Test your soil pH and amend as needed.
Remove all weeds before planting. Perennials compete poorly with weeds. Use a garden fork to loosen soil 12 inches deep.
Add 2 to 3 inches of compost. Mix it into the top 6 inches of soil. This improves drainage and fertility.
Planting Time
Spring is the best time to plant most perennials in Arkansas. Wait until after the last frost. For fall planting, do it 6 weeks before the first frost.
Dig holes twice as wide as the root ball. Set plants at the same depth they were in the pot. Water well after planting.
Space plants according to their mature size. Crowding leads to disease and poor production. Follow the spacing guidelines for each vegetable.
Watering
Water deeply once a week during dry spells. Perennials have deep roots, so they need less frequent watering. But they need consistent moisture when establishing.
Use soaker hoses or drip irrigation. This keeps water off the leaves and reduces disease. Water in the morning to allow leaves to dry.
Mulching
Apply 2 to 3 inches of organic mulch around plants. Use straw, wood chips, or shredded leaves. Mulch keeps soil cool, retains moisture, and suppresses weeds.
Keep mulch away from plant stems. This prevents rot and pest problems. Refresh mulch each spring.
Fertilizing
Fertilize perennials in early spring. Use a balanced 10-10-10 fertilizer or compost. Apply again in midsummer for heavy feeders.
Side-dress with compost in fall. This feeds the roots over winter. Avoid high-nitrogen fertilizers late in the season.
Winter Care
Most perennials need little winter care in Arkansas. Cut back dead foliage after frost. Leave a few inches of stems to mark the plant location.
Mulch heavily in colder zones. Use straw or leaves to protect roots. Remove mulch in early spring.
Some perennials benefit from a cold frame. This extends the harvest into winter. Use it for kale, spinach, and other greens.
Common Pests And Problems
Perennial vegetables face fewer pest problems than annuals. But they still have issues. Here’s what to watch for in Arkansas.
Asparagus beetles attack spears and ferns. Hand-pick them or use neem oil. Keep the bed clean to reduce overwintering sites.
Slugs and snails love tender greens. Use beer traps, copper tape, or diatomaceous earth. Remove hiding spots like boards and debris.
Deer and rabbits can damage perennials. Use fencing or repellents. Plant strong-smelling herbs like mint nearby.
Root rot happens in poorly drained soil. Improve drainage with raised beds. Avoid overwatering, especially in clay soil.
Powdery mildew affects some perennials in humid weather. Space plants for good air circulation. Use sulfur spray if needed.
