I’ve been purchasing bulbs from A.D.R. for many years. The quality is superior and the service fantastic. Chris and his family have always been prompt and accommodating. If you need it, Chris can find it! I wouldn’t shop anywhere else!

Oxalis 'Regnelli'

Lucky Shamrock

Oxalis regnellii, commonly known as Green Shamrock, is a compact, bulbous perennial prized for its clover-like, bright green foliage and delicate white flowers. The leaves fold at night and reopen during the day, adding a dynamic element to its charm.

Thriving in bright, indirect light, Oxalis regnellii prefers well-drained soil and is ideal for indoor cultivation or shaded garden beds. It is low-maintenance and can be grown in containers or as a seasonal accent plant. This variety is often associated with good luck, making it a popular choice for festive displays.

Growing and Maintenance Tips for Oxalis 'Regnelli'

Planting: Plant bulbs just below the surface in a well-draining potting mix (a peat-based or standard houseplant blend works well). Use a container with drainage holes.
Spacing: Place bulbs 1 to 2 inches apart for a full look.
Light: Prefers bright, indirect light. An east-facing window is ideal. Too much direct sun can scorch leaves, while too little light may cause leggy growth.
Watering: Water when the top inch of soil feels dry. Avoid overwatering—Oxalis dislikes soggy roots. Reduce watering during dormancy (often in summer or after blooming).
Temperature & Humidity: Thrives at 60–75°F. Protect from drafts and temperature swings. Tolerates average indoor humidity without issue.
Fertilization: Feed once a month during active growth (spring and fall) with a balanced liquid fertilizer diluted to half strength.
Dormancy: If leaves yellow and die back, the plant may be entering dormancy. Stop watering, let it rest in a cool, dry spot for a few weeks, then resume watering to encourage regrowth.
Propagation: Divide bulbs or offsets when repotting. Each section should have 3+ growing points for best success.
Pest & Disease: Generally pest-free. Watch for root rot if overwatered. Toxic if ingested—keep away from pets and children.
