Zephyranthes ‘blanc’ sp?

The exact species of this white-flowered Zephyranthes is not stated with certainty, but its characteristics match those of the Zephyranthes candida group, native to the Rio de la Plata region of South America. This small bulbous plant of the family Amaryllidaceae forms a clump of narrow, fine, evergreen leaves. White, crocus-shaped flowers with yellow stamens appear singly or in small groups, often just after rain, from late summer to autumn. It likes full sun, well-drained soil, and tolerates drought.
