Ohio’s Top 5 Perennial Edibles for Year-Round Gardening

Gardening enthusiasts in Ohio are blessed with a climate that supports a diverse array of plants, making it possible to cultivate year-round food sources. Perennial edibles, in particular, are a fantastic option for those looking to minimize labor while maximizing yield. Unlike annuals, which require replanting each season, perennials return year after year, providing fresh produce with minimal effort. This article will explore five top perennial edibles ideal for Ohio gardeners.

1. Asparagus (Asparagus officinalis)

Overview

Asparagus is one of the most beloved perennial vegetables and thrives well in Ohio’s temperate climate. Once established, asparagus can produce spears for 15 years or more, making it a worthwhile investment in any garden.

Growing Conditions

• Soil: Asparagus prefers well-drained, sandy loam with a pH level between 7.0 and 8.0.
• Sunlight: Full sun is essential for optimal growth.
• Water: While they require regular watering during the growing season, mature plants are relatively drought-tolerant.

Planting Tips

• Timing: The best time to plant asparagus crowns is in early spring, as soon as the soil can be worked.
• Spacing: Plant crowns 12 to 18 inches apart in rows spaced 3 to 4 feet apart.
• Harvesting: After planting, allow the plants to grow undisturbed for three years. In the fourth year, begin harvesting spears when they reach about 6 to 8 inches tall.

Culinary Uses

Asparagus is incredibly versatile; it can be grilled, roasted, sautéed, or steamed. Incorporate it into salads, pasta dishes, or serve it as a side dish drizzled with olive oil and lemon juice.

2. Rhubarb (Rheum rhabarbarum)

Overview

Rhubarb is often considered a fruit due to its culinary uses but is technically a vegetable. Known for its tart flavor, rhubarb thrives in Ohio’s cooler climate and can be harvested starting in late spring.

Growing Conditions

• Soil: Rhubarb prefers rich, well-drained soils that are high in organic matter.
• Sunlight: Full sun is ideal; however, it can tolerate partial shade.
• Water: Consistent moisture is key during the growing season.

Planting Tips

• Timing: You can plant rhubarb crowns in early spring or fall.
• Spacing: Space plants about 3 feet apart to allow for their expansive growth.
• Harvesting: Avoid harvesting any stalks during the first year; in subsequent years, harvest stalks when they reach around 12 inches long but leave enough for the plant to continue thriving.

Culinary Uses

Rhubarb is famously used in pies and crumbles but can also be made into jams or sauces. Pair it with strawberries for a classic dessert or add it to savory dishes for a unique twist.

3. Jerusalem Artichoke (Helianthus tuberosus)

Overview

Jerusalem artichokes, also known as sunchokes, are tuberous roots of a type of sunflower native to North America. These hardy perennials are easy to grow and offer a nutty flavor reminiscent of artichokes.

Growing Conditions

• Soil: They thrive in well-drained soil but are adaptable to various soil types.
• Sunlight: Full sun promotes robust growth.
• Water: Sunchokes require moderate watering and can tolerate dry spells once established.

Planting Tips

• Timing: Plant tubers in early spring after the last frost date.
• Spacing: Space tubers about 12 inches apart; they will spread over time.
• Harvesting: Tubers can be harvested from fall through spring; they taste better after a frost when their starches convert to sugars.

Culinary Uses

Jerusalem artichokes can be eaten raw in salads or cooked like potatoes—mashed, roasted, or sautéed. They’re also excellent for purees and soups due to their creamy texture when cooked.

4. Chives (Allium schoenoprasum)

Overview

Chives are a member of the onion family and one of the easiest herbs to grow as a perennial in Ohio gardens. Their mild onion flavor makes them an excellent addition to various dishes.

Growing Conditions

• Soil: Chives prefer fertile soil that drains well.
• Sunlight: Full sun is preferred but can tolerate partial shade.
• Water: Regular watering helps maintain lush green growth.

Planting Tips

• Timing: Chives can be divided or planted in early spring.
• Spacing: Space plants about 12 inches apart; they will spread through self-seeding.
• Harvesting: Snip leaves as needed throughout the growing season; frequent harvesting encourages new growth.

Culinary Uses

Chives add flavor to salads, soups, omelets, and dips. They also make an attractive garnish for many dishes due to their bright green color and delicate flowers.

5. Oregano (Origanum vulgare)

Overview

Oregano is a robust herb known for its aromatic leaves and versatility in cooking. It thrives in Ohio’s climate and adds flavor to various dishes from Italian cuisine to Greek salads.

Growing Conditions

• Soil: Oregano prefers well-drained sandy or rocky soil with good fertility.
• Sunlight: Full sun exposure results in the best flavor profile.
• Water: While oregano is drought-resistant once established, regular watering helps during dry spells.

Planting Tips

• Timing: Plant oregano in early spring after the last frost date.
• Spacing: Space plants around 12 inches apart since they tend to spread out.
• Harvesting: Harvest leaves throughout the growing season; cutting back plants encourages bushier growth.

Culinary Uses

Oregano is often used fresh or dried in marinades, dressings, pastas, and pizzas. Its aromatic nature enhances dishes without overpowering other flavors.
