Canna 'Greenleaf Picasso'

Greenleaf Picasso Canna Lily (Canna ‘Greenleaf Picasso’) is a compact, highly floriferous rhizomatous perennial admired for its large bright yellow flowers marked with irregular red spots. This spectacular two-tone colouring stands out brilliantly against broad, lush green foliage that enhances the plant’s tropical appearance. Blooming from July to September, it reaches approximately 80 to 100 cm (32 to 39 in) in height and keeps summer landscapes colourful until the first cold weather arrives. Its dense, well-structured habit performs beautifully in both flower beds and containers. Hardy only to Zone 10, it must be protected from frost in Quebec.

Plant the rhizomes in spring after all danger of frost has passed and the soil has warmed thoroughly. Position them horizontally, approximately 10 cm (4 in) deep, and space them 40 to 50 cm (16 to 20 in) apart. Choose a location in full sun with rich, fertile, organic, evenly moist, and well-drained soil. Water generously throughout active growth to maintain consistent moisture without allowing standing water. Regular applications of compost and a balanced fertilizer every two weeks encourage vigorous growth and abundant flowering. Before the first frost, lift the rhizomes and store them in a cool, dry place.

‘Greenleaf Picasso’ canna lily is ideal for tropical flower beds, borders, patios, large containers, and exotic garden displays. For container growing, choose a pot at least 45 cm (18 in) in diameter with excellent drainage. Its yellow flowers spotted with red pair beautifully with caladiums, alocasias, coleus, begonias, and ornamental grasses to create lush, colourful plantings. The blooms attract a variety of pollinators and quickly become a striking focal point in the garden. Although some canna species are consumed in certain tropical regions, no culinary use is recommended for this specific cultivar.
