Through the years I've tried just about everyone for bulbs but A.D.R. is tops. It's a family run business and the service levels and expertise are as good as the product they sell. My clients rave about the results we get with A.D.R. and that makes me happy.

Calla 'Rehmanni' (Ships in Spring)

Zantedeschia

Calla Lily 'Rehmannii' is a compact variety known for its soft pink blooms with a creamy blush along the edges. The flowers rise above semi-erect, lance-shaped green leaves, which differ from the arrow-shaped foliage of other calla species. Blooming from midsummer to early fall, this variety grows up to 16–20 inches tall and thrives in full sun with moist, well-drained soil. Hardy in USDA zones 8 to 10, it can be grown as an annual in colder climates, with rhizomes lifted and stored for winter. It performs well in borders, containers, and near water features, adding a graceful presence to garden designs.

Growing and Maintenance Tips for Calla 'Rehmanni' (Ships in Spring)

Planting: In spring, plant rhizomes after the last frost when soil has warmed to at least 60°F. Set them just below the surface—about 3 to 4 inches deep—with the growing points facing upward.
Location: Choose a spot in full sun or partial shade. In hotter climates, afternoon shade helps prevent stress.
Soil: Use fertile, humus-rich, moist but well-drained soil.
Watering: Keep soil consistently moist during active growth, especially in dry spells. Avoid waterlogging.
Temperature: Ideal range is 60–75°F. In zones below 8, grow as annuals or lift rhizomes in fall.
Fertilization: Feed every 2–3 weeks with a high-potash fertilizer—liquid seaweed is a great organic option.
Pruning: Remove spent blooms and yellowing foliage to tidy the plant and encourage new growth.
Pest & Disease: Watch for aphids, thrips, and fungal issues. Ensure good air circulation and avoid soggy soil.
Propagation: Divide rhizomes in spring before planting.
