Alberto Castillo Ipheion is a refined snow-white cultivar of the Spring Starflower, known botanically as Ipheion uniflorum. This hardy bulb produces delicate star-shaped flowers on multiple stems in very early spring, reaching just 4 inches tall, and thrives in hardiness zones 5 and warmer. It's renowned for its fragrance and remarkable ease of cultivation, naturalizing readily once established to create luminous early-season carpets in lawns, woodland borders, and rock gardens.

The Alberto Castillo cultivar produces pristine white, star-shaped flowers that emerge on multiple stems from a single small bulb, releasing fragrance in the chill of early spring before most other plants have awakened. Ipheion is celebrated among gardeners for being one of the easiest bulbs to grow; it asks for little beyond well-draining soil and will spread naturally year after year. The compact 4-inch height makes it particularly charming when massed in drifts or paired with spring bulbs like Muscari, creating striking early-season tapestries across the garden.
Alberto Castillo Ipheion excels as an ornamental spring bulb for naturalizing in lawns and creating early-season displays. It's prized for massing in woodland borders, rock gardens, and container plantings where its delicate white flowers and fragrance can be appreciated up close. The compact stature and reliable spring bloom make it ideal for interplanting with other small bulbs and perennials to extend the season of ornamental interest.
