Romulea clusiana is a captivating, small geophyte known for its vivid, goblet-shaped flowers in shades of deep violet to magenta, often highlighted by a bright yellow throat and contrasting dark center. These striking blooms appear in early spring, typically opening in full sun, and are a brilliant sight in rock gardens or container plantings.
Native to sandy and rocky soils across the western Mediterranean region—particularly in southern Spain, Portugal, and parts of North Africa—R. clusiana thrives in open, well-drained habitats that experience mild, wet winters and hot, dry summers. This seasonal rhythm is key to its success in cultivation.
In the garden, Romulea clusiana prefers full sun and sharply draining soil, such as a gritty mix or sandy loam. It is ideal for alpine troughs, bulb frames, or containers where summer dormancy can be respected. Plants grow to about 3 to 5 inches tall and form grassy, fine-textured foliage that disappears in late spring.
This species is hardy to approximately USDA Zone 8, tolerating light frost but best protected from prolonged freezing. In colder climates, it should be overwintered under cover or grown in pots that can be brought indoors. With its vibrant color and petite form, Romulea clusiana is a treasure for collectors and lovers of Mediterranean bulbs.
