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.
