Barbara Schuler, Custom Gardens, 833-8110. Blooming in late summer, the fragrant blossoms last 3 to 5 days and close up at night, says Barbara. This plant does like at least 6 hours of sun per day, but I have seen it blossom in semi-shade when fertilized well. Almost all parts of the plants are edible. Most varieties need to be planted in no more than 24 inches of water, some varieties can only tolerate depths up to 18 inches.
Foliage can drown if planted too deep.
Beautiful blossoms late spring-fall. A cold snap can cause the plant to stop blooming, so it is best to not put the tropical lilies in the pond until the water temperature is around 70 degrees Fahrenheit. Long floating roots are excellent filters for the water, removing not only natural toxins from the water but some chemical pollutants as well. Fast growers, simply float these plants on the surface of the water. Bloom lavender spikes in June-August.
