Zantedeschia 'Picasso' Calla Lily Bulbs

'Picasso' Calla Lily is a rhizomatous perennial (Zones 8-10) native to South Africa, renowned for its extraordinary 2- to 3-inch trumpet-shaped blooms featuring dark purple throats and creamy white rims. These unique bicolor flowers emerge in mid to late summer, making them coveted additions to summer bouquets and mixed floral arrangements. The blooms rise above large, lightly speckled, arrow-shaped leaves on lush plants that typically mature to 12 to 36 inches tall.

This calla lily serves as an excellent specimen plant and is particularly striking when grouped in garden beds, borders, and containers. Planting three bulbs can fill a 10- to 12-inch patio pot beautifully. Additionally, 'Picasso' can be grown indoors as a houseplant in a sunny window, making it a must-have for cutting gardens.

Calla lilies are easy to grow, thriving in sunny to partially shady locations with loose, medium moist, well-draining soil. While best flowering occurs in full sun, providing afternoon shade in warmer climates can be beneficial. Plant 'Picasso' calla lily bulbs in warm spring soil after the threat of frost has passed, spacing them 12 to 24 inches apart and 4 inches deep, with the 'eyes' or growing points facing upwards. Maintain consistent watering and fertilization during the growing season, ensuring the soil remains moist but not waterlogged.

In regions subject to frost, treat calla lilies as annuals or dig up the bulbs in fall for overwintering. Store them in a cool, dry place and replant in spring to enjoy their exquisite blooms year after year.
