Georgia’s heat and humidity require perennial vegetables that resist disease and keep producing through summer. Finding the best perennial vegetables in Georgia means choosing plants that thrive in both the scorching July sun and the mild winters of zones 7-9. These low-maintenance crops come back year after year, saving you time and money on replanting.
Perennial vegetables are a smart choice for Georgia gardens. They establish deep root systems that handle drought better than annuals. They also build soil health over time. Let’s look at the top options that actually work in Georgia’s climate.
Best Perennial Vegetables In Georgia
When you plant these vegetables once, you harvest for years. The key is matching each plant to your specific microclimate. Georgia ranges from the mountains in the north to the coastal plains in the south, so some varieties perform better in certain areas.
Asparagus: A Long-Term Investment
Asparagus is one of the most reliable perennial vegetables for Georgia gardens. It thrives in well-drained soil and full sun. Once established, a bed can produce for 15-20 years.
Choose varieties like ‘Jersey Knight’ or ‘Purple Passion’ that resist fusarium wilt. Georgia’s humidity can cause crown rot, so plant in raised beds if your soil stays wet. Space crowns 12-18 inches apart in trenches 6-8 inches deep.
Harvest sparingly in the second year. By year three, you can cut spears for 6-8 weeks each spring. Stop harvesting when spears get thin, about pencil-width. Let the ferns grow to feed the roots for next year.
Rhubarb: A Cool-Season Surprise
Rhubarb is tricky in Georgia because it needs winter chill. It grows best in north Georgia where temperatures drop below 40°F for several weeks. In south Georgia, it often struggles.
Plant ‘Victoria’ or ‘Crimson Red’ in partial shade to protect from afternoon heat. Mulch heavily with pine straw to keep roots cool. Water consistently during dry spells. Rhubarb leaves are toxic, so only eat the stalks.
Harvest stalks when they are 12-18 inches long. Pull them gently from the base. Leave at least half the stalks to keep the plant healthy. Stop harvesting by early July to let the plant store energy.
Artichokes: Globe And Jerusalem
Globe artichokes are perennial in Georgia if you treat them right. They need cool winters and mild summers. In north Georgia, they overwinter easily. In south Georgia, they may need shade cloth during heat waves.
Plant ‘Green Globe’ or ‘Imperial Star’ in rich, well-drained soil. Space them 4 feet apart. They grow large, so give them room. Water deeply once a week. Harvest buds before they open, cutting 2-3 inches of stem.
Jerusalem artichokes, also called sunchokes, are completely different. They are native to North America and grow like weeds in Georgia. Plant tubers in spring, harvest in fall after frost. They spread aggressively, so contain them in a raised bed or large pot.
Perennial Onions: Egyptian Walking Onions
Egyptian walking onions are the easiest perennial vegetable for Georgia. They produce small bulbs at the top of the stalk that fall over and plant themselves. This gives you a continuous supply of green onions.
Plant sets in fall or early spring. They tolerate poor soil and partial shade. Harvest the green tops anytime. The underground bulbs are stronger flavored. Use them like shallots or garlic.
These onions multiply quickly. Share extras with neighbors or move them to new beds. They rarely suffer from pests or diseases in Georgia’s climate.
Perennial Kale: Tree Collards And Walking Stick Kale
Tree collards are a Georgia specialty. They grow 6-8 feet tall and produce leaves year-round. Unlike annual kale, they don’t bolt in summer heat. The leaves get sweeter after frost.
Start with cuttings from an established plant. Root them in water or soil. Plant in full sun with rich soil. Space them 3-4 feet apart. Harvest outer leaves regularly to encourage new growth.
Walking stick kale grows even taller, up to 10 feet. It produces large, frilly leaves. Both types need protection from deer and rabbits. Use netting or fencing around young plants.
Perennial Spinach: New Zealand Spinach
New Zealand spinach is not true spinach, but it tastes similar. It thrives in Georgia’s heat when regular spinach bolts. It spreads as a ground cover, producing tender leaves all summer.
Soak seeds overnight before planting. Sow directly in the garden after last frost. Space plants 12 inches apart. Harvest the tips and young leaves regularly. The more you pick, the more it grows.
This plant reseeds easily. Once you have it, you’ll likely see volunteers every year. It handles drought well but tastes better with regular water.
Perennial Beans: Scarlet Runner Beans
Scarlet runner beans are technically perennials in Georgia. They die back in winter but regrow from the roots each spring. They produce edible pods and beautiful red flowers that attract hummingbirds.
Plant seeds after frost in rich, moist soil. Provide a strong trellis or fence. They climb 10-15 feet. Harvest pods when young and tender. Leave some to dry for seeds next year.
These beans prefer cooler weather. In south Georgia, plant them in partial shade. Mulch the roots heavily to protect from summer heat. They produce best in spring and fall.
Perennial Herbs That Double As Vegetables
Some herbs serve as both seasoning and vegetables. Sorrel is a lemony green that grows in Georgia year-round. Use it in salads or soups. It spreads quickly, so contain it in a pot or bed.
Good King Henry is an ancient vegetable that produces spinach-like leaves. It tolerates shade and poor soil. Harvest the young shoots like asparagus in spring. The leaves are good cooked or raw.
Sea kale is another option. It grows in coastal Georgia’s sandy soil. Blanch the shoots by covering them with soil or a pot. This makes them tender and mild.
Planting And Care Tips For Georgia
Timing matters for perennial vegetables in Georgia. Plant most perennials in fall or early spring. Fall planting gives roots time to establish before summer heat. Spring planting works too, but water regularly.
Soil preparation is critical. Most perennials need well-drained soil with organic matter. Add compost or aged manure before planting. Test your soil pH. Most prefer 6.0-7.0.
Mulch is your best friend in Georgia. Use pine straw, wood chips, or leaves. Mulch keeps roots cool, retains moisture, and suppresses weeds. Apply 2-4 inches deep around each plant.
Water deeply but infrequently. Perennials develop deep roots that find water. Overwatering causes root rot. Water once a week during dry spells. More often in sandy soil.
Fertilize lightly in spring with a balanced organic fertilizer. Too much nitrogen causes lush growth that attracts pests. Compost tea or fish emulsion works well. Avoid synthetic fertilizers that burn roots.
Pest And Disease Management
Georgia’s humidity brings fungal diseases. Prevent them by spacing plants for air flow. Water at ground level, not on leaves. Remove diseased leaves promptly. Use copper fungicide if needed.
Common pests include aphids, slugs, and Japanese beetles. Hand pick beetles and slugs. Spray aphids with neem oil or insecticidal soap. Encourage beneficial insects like ladybugs and lacewings.
Deer and rabbits love tender perennial greens. Use fencing at least 4 feet tall for deer. Chicken wire works for rabbits. Motion-activated sprinklers also help. Some gardeners use repellents like garlic spray.
Harvesting And Storing Perennial Vegetables
Harvest most perennials in the morning when they are crisp. Use clean, sharp tools to avoid damaging plants. Cut leaves and stems at the base. Leave enough foliage for the plant to recover.
Store harvested vegetables in the refrigerator. Most last 3-5 days. Blanch and freeze extras for winter. Asparagus freezes well. Tree collards keep in the fridge for a week.
Some perennials produce in flushes. Harvest regularly to encourage more growth. If a plant slows down, give it a break. Stop harvesting for a few weeks to let it recover.
Extending The Growing Season
Use row covers or shade cloth to protect perennials from extreme weather. In summer, shade cloth reduces heat stress. In winter, row covers protect from frost. This extends your harvest window.
Plant perennials in microclimates. South-facing slopes warm up faster in spring. North-facing slopes stay cooler in summer. Use walls or fences to create warm spots. Water features moderate temperature.
Succession planting works for some perennials. Plant early and late varieties of the same crop. This spreads out the harvest. For example, plant early and late asparagus varieties.
Companion Planting With Perennials
Perennial vegetables benefit from companion plants. Plant herbs like thyme and oregano nearby. They repel pests and attract pollinators. Avoid planting perennials near aggressive spreaders like mint.
Use flowers to attract beneficial insects. Marigolds, nasturtiums, and calendula are good choices. They draw in predators that eat aphids and caterpillars. Plant them around the edges of your perennial bed.
Some perennials improve soil for others. Comfrey accumulates nutrients and adds organic matter. Plant it near heavy feeders like artichokes. Borage attracts bees and adds trace minerals.
Common Mistakes To Avoid
One mistake is planting too many perennials at once. Start with a few types and expand. Perennials take time to establish. Overcrowding leads to competition and disease.
Another mistake is neglecting soil preparation. Perennials live for years, so poor soil limits their potential. Take time to amend soil before planting. Add compost, adjust pH, and ensure drainage.
Ignoring local conditions is also a problem. What works in north Georgia may fail in south Georgia. Check your hardiness zone and microclimate. Talk to local gardeners for advice.
Finally, don’t give up too soon. Some perennials take 2-3 years to produce well. Asparagus and artichokes are examples. Be patient and maintain care. The wait is worth it.
