Nursery contributed plant descriptions

Quite beautiful Chilean perennial with succulent gray-green leaves and large, bright purple flowers that nod on the top of tall, sometimes 2.5' tall, stems above the low-growing foliage. Height 12-15" and 36" in width. Plant in full sun with well-drained, slightly acidic soil. Will tolerate a variety of soil types and conditions, including coastal areas. A great pollinator and bee attractor, it's excellent in rock gardens or as a mass planting where it is allowed to spread and form a small carpet. Drought tolerant. Frost hardy to USDA zone 8, but treated as a re-seeding annual in colder climates. Portulacaceae
