Gopher Plant vs Kohlrabi Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Gopher Plant
Euphorbia rigida
Euphorbia rigida, commonly known as Gopher Plant, is a succulent shrub characterized by its rigid, upright stems and bluish-gray, fleshy leaves. It typically grows to a height of 1-3 feet. The plant produces small, inconspicuous yellow flowers surrounded by showy bracts in spring. It is primarily an outdoor plant, valued for its architectural form and drought tolerance in xeriscaping. While some may attempt to grow it indoors, it requires very bright light and excellent drainage to thrive, making it challenging.
Kohlrabi
Brassica oleracea var. gongylodes
Kohlrabi is a biennial vegetable cultivated as an annual, known for its swollen, globular stem that grows above ground. It features a crisp, mild flavor similar to a turnip or cabbage. The plant has long-stalked leaves emerging from the bulbous stem. It is primarily grown outdoors in gardens and farms for its edible stem and leaves. While it can be started indoors, it requires full sun and ample space to thrive, making it challenging to grow to maturity indoors. People grow kohlrabi for its unique texture and flavor in salads, stir-fries, and other culinary applications.

💧 Watering Needs
Gopher Plant
Allow soil to dry completely between waterings. Overwatering can lead to root rot. Water thoroughly when the soil is dry to the touch, then allow excess water to drain away. Reduce watering frequency during the dormant winter months. Signs of overwatering include yellowing leaves and stem rot. Underwatering results in shriveled leaves and stunted growth.
Kohlrabi
Water deeply when the top inch of soil feels dry. Avoid overwatering, which can lead to rot. Consistent moisture is important for bulb development. Signs of underwatering include wilting leaves and stunted growth. Overwatering can cause yellowing leaves and a mushy stem.

❓ Frequently Asked Questions — Comparing These Plants
Gopher Plant
What are the light requirements for Gopher Plant?
Gopher Plant requires bright, indirect sunlight to thrive. Insufficient light can lead to etiolation, where the plant becomes leggy and pale. Place your Gopher Plant near a sunny window, preferably facing south or west. If natural light is limited, supplement with a grow light.
How do I care for Gopher Plant?
Gopher Plant thrives in bright, indirect sunlight; provide at least 6 hours of sunlight daily. Water sparingly, allowing the soil to dry out completely between waterings to prevent root rot. Use well-draining succulent soil to ensure proper drainage. A cactus mix amended with perlite or pumice is ideal.
How do I propagate Gopher Plant?
Gopher Plant can be propagated using leaf cuttings, offsets, or stem cuttings. For leaf cuttings, allow the cut end to callus for a few days before placing it on well-draining soil. Water sparingly until roots develop. Offsets, small plants that grow at the base of the parent plant, can be carefully separated and planted in their own pots.
Kohlrabi
What are the light requirements for Kohlrabi?
Kohlrabi thrives in full sun, requiring at least 6 hours of direct sunlight per day to produce healthy bulbs. Insufficient light can lead to leggy growth and smaller, less flavorful bulbs. In hotter climates, providing some afternoon shade can prevent the plant from bolting (prematurely going to seed). When growing indoors, place Kohlrabi near a south-facing window or use grow lights to supplement natural light. Rotate the plants regularly to ensure even light exposure on all sides. Monitor the leaves for signs of insufficient light, such as pale color or elongated stems, and adjust the light accordingly.
How do I care for Kohlrabi?
Kohlrabi requires well-draining soil rich in organic matter. Plant seeds directly in the garden or start indoors 4-6 weeks before the last frost. Space plants 6-8 inches apart in rows 12-18 inches apart. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks with a balanced fertilizer, paying attention to potassium levels to promote strong bulb development. Kohlrabi prefers full sun but can tolerate partial shade, especially in warmer climates. Harvest when the bulb reaches 2-3 inches in diameter for the best flavor and texture. Protect from pests like cabbage worms and aphids with appropriate organic pest control methods. Rotate crops annually to prevent soilborne diseases.
How do I propagate Kohlrabi?
Kohlrabi is typically propagated by seed, but it is possible to propagate it through vegetative methods, although less common.
