Plant in full sun and irrigate regularly - multiplies best if kept in wet or even boggy soils but is not finicky of soil type. Evergreen in frost free gardens and root hardy to USDA Zone 7 (0-10°F) where it benefits from protective mulch. This old garden hybrid spider lily probably came from somewhere in the Caribbean's but now inhabits many landscapes and even persists in old, abandoned home sites throughout the South. It is one of the most reliable of the spider lilies and the name "Everyman's Hymenocallis" was coined by Thad Howard in his book "Bulbs for Warms Climates". Howard also notes that the name "Tropical Giant" was a nickname that was given to the plant by Cecil Houdyshel, a Herbert medal winner (1938), and friend and contemporary of Luther Burbank. Most now consider the plant to be a nice form of Hymenocallis carribea.

We first acquired plants of this cultivar from Steve Lowe of the San Antonio Botanic Garden in 2005 and later that year acquired our stock for our crops from the micropropagation laboratory (tissue culture) at the now closed Shady Oaks Nursery sold this plant from 2006 to 2007 but discontinued growing such plants that were part of our as part of our Aquatic Plants Program as we transitioned away from such thirsty plants. 

This information about Hymenocallis 'Tropical Giant' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
