I have worked with A.D.R. Bulbs for almost 5 years now, and my company has sourced bulbs with them for longer than that. Communication is great - from ordering, to deliveries, to follow-ups on final product. I love the quality of the product as well as the service. We plant nearly 100,000 bulbs and A.D.R. keeps the whole process easy for us!

Calla 'Picasso' (Ships in Spring)

Zantedeschia

Calla Lily 'Picasso' is a striking variety featuring dark purple trumpet-shaped blooms with white rims. The flowers rise above elegant, dark green, arrow-shaped leaves speckled with lighter freckles, adding texture and depth to garden beds and containers. Blooming from summer to fall, this variety 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 bulbs lifted and stored for winter. 'Picasso' is deer and rabbit resistant, making it a reliable choice for floral displays.

Growing and Maintenance Tips for Calla 'Picasso' (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.
