Our "Bloom or Bust" Promise

Alberto Castillo, often admired for its white colouring, is a bulb variety especially well suited to naturalising.

Ipheion ‘Alberto Castillo’ is a quietly distinguished little starflower, prized for its crisp white, starry blooms, each petal finished with the most delicate hint of green at the centre. Emerging in late winter and carrying on through early spring, it makes a neat, light-green carpet that looks wonderfully composed in drifts.

Superb for naturalising through grass, threading beneath shrubs and roses, or bringing a fresh note to patio pots by the door. Fully hardy and notably unfussy, it’s an elegant way to lift the garden when the season still feels young.

  • Flowering: February–April
  • Height: 20cm
  • Bulb size: 5/6cm
  • Best for: naturalising, containers, underplanting

Please note: Deer resistance can vary by location and pressure; this variety is generally avoided, but cannot be guaranteed.

Where to Plant:

Ipheion 'Alberto Castillo' (starflower) needs full-sun, partial sun and a warm, sheltered position for the best flowering. Plant into fertile, humus-rich soil that drains well, and choose a spot protected from strong winds, especially for taller varieties.

How to Plant:

Plant bulb from September to December once conditions are suitable. Set them at the correct depth for the variety, spacing 8–10cm apart where relevant, then firm in gently and water well after planting.

Aftercare:

Water regularly in dry weather and feed every two to three weeks once buds appear. Stake taller stems early and deadhead to keep plants flowering. After flowering, allow foliage to die back naturally before lifting or protecting bulb according to local conditions.
