Often grown as cut flowers, Alstroemeria have colorful, funnel-shaped flowers, often with contrasting markings. The plants form clumps up to 2 feet across. The grayish green leaves are only 3 to 5 inches long, but the flower spikes can reach 3 feet in some species. Use in a mixed or perennial border, alpine house, or cutting garden.
