Introduced in 1990 by Dutch breeder A.M. Könst, this hybrid Alstroemeria commemorates an era when breeding programs were pushing the genus beyond its Andean origins into something altogether more versatile. Growing to four feet tall and three feet wide in zones 7 to 11, Casablanca is notably more robust than many of its relatives, spreading steadily by thick rhizomes through well-drained, fertile soil in full sun. The flowers are properly white, not cream, with distinctive maroon markings concentrated on the inner petals and a pink flush visible on the reverse — a detail most appreciated when stems are brought indoors.

Hummingbirds, bees, and butterflies all visit the blooms throughout the season, which makes it worth including even in gardens where cut flowers are not the primary goal. It carries strong disease resistance and requires little intervention once established. Handle with gloves, as the sap can irritate skin and eyes. In a pollinator border, a cottage cutting patch, or massed along a sunny fence, Casablanca earns its keep for the length of the growing season.
