A variety of storm lily, Zephyranthes primulina, ht 20 cm), is a dainty member of the Amaryllidaceae family of bulbs. This species name was what it was sold it to me as, though I can find no reference to it in any of my books. The genus is native to Central and Southern America and the Caribbean. This species has thin grassy foliage and soft yellow flowers like a crocus, and is easily grown in Sydney. It is very similar to the white-flowered Zephyranthes candida, which is autumn-blooming. It appears to be evergreen and flowers in December and early January. It has a tendency to come into bloom after rain has fallen, hence the common name, and several flushes of flowers can be expected if there a few periods of rain in early summer. Thick clumps of bulbs will form and they can survive in quite dry positions, such as at the base of a hedge. This species produces a lot of seed. They will grow in sun or part-shade and can be cultivated in pots.
