Florida Celestial Lily Plant Care

Florida Celestial Lily (Nemastylis floridana) belongs to the Iridaceae family within the Nemastylis genus. Florida Celestial Lily is native to Florida in the United States. Florida Celestial Lily is also known as Florida Prairie Lily.

Florida Celestial Lily displays a low rosette, clumping growth habit, reaching up to 0.5 ft tall with a spread of approximately 0.5 ft. Florida Celestial Lily produces star-shaped blue flowers with yellow centers.

Leaf size: approximately 6 inches.

Water a young or newly planted Florida Celestial Lily every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Florida Celestial Lily thrives in full sun to partial shade.

Nemastylis floridana tolerates temperatures of 50–80°F. Florida Celestial Lily prefers humidity levels of 40–60%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Florida Celestial Lily to prevent waterlogging, which leads to root rot and fungal issues.

Feed Florida Celestial Lily every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Florida Celestial Lily is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Florida Celestial Lily can spread to about 1 ft (0.2 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Florida Celestial Lily while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Florida Celestial Lily is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Florida Celestial Lily can be propagated through seeds, division of offsets. Similar propagation techniques also apply to twinflower celestial lily plant care, which shares the same genus.
