Zephyranthes atamasco (Linnaeus) Herbert is a spring flowering species of the southern United States (Virginia to Florida and west to Alabama) usually found in swamps and damp clearings. Broad grassy foliage appears in winter and plants go dormant in summer. The white flowers are very large. Zephyranthes are unobtrusive, summer-flowering bulbs that can fit in any garden, with a flower color range from yellow to white to pink. The great thing about zephyranthes is the lack of large foliage that often accompanies many other spring-flowering bulbs.
The North American Lily Society recommends the generous use of a 10-10-10 type granular fertilizer, scratched into the soil and watered in well when sprouts emerge in spring. Smaller feedings can be applied at regular intervals thereafter -- every 4 to 6 weeks or so -- during the growing season, always watered in well.
It thrives in limestone soil, made light with leaf mould and grit, and mixed with plenty of broken fragments;
Deadheading is what to do when lilies have finished flowering. The care for lilies after flowering begins with deadheading. Spent flowers should be removed regularly. Lily blooms can be cut off and used as cut flowers for decoration and making floral displays either alone or with other flowers.
The entire lily plant is toxic: the stem, leaves, flowers, pollen, and even the water in a vase. Eating just a small amount of a leaf or flower petal, licking a few pollen grains off its fur while grooming, or drinking the water from the vase can cause your cat to develop fatal kidney failure in less than 3 days.
