Products > Dietes grandiflora 'Gray Ghost'   Dietes grandiflora 'Gray Ghost' - Gray Striped Fortnight Lily     [2nd Image] Habit and Cultural Information Category: Perennial Family: Iridaceae (Irises) Origin: South Africa (Africa) Evergreen: Yes Flower Color: White Bloomtime: Spring/Summer Height: 3-4 feet Width: 2-3 feet Exposure: Sun or Shade Irrigation (H2O Info): Medium Water Needs Winter Hardiness: 15-20° F Dietes grandiflora 'Gray Ghost' (Gray Striped Fortnight Lily) - This evergreen rhizomatous perennial produces clumps of long, upright narrow leaves that reach 3 feet tall. Unlike the species, this selection has gray-green leaves that have with creamy-white marginal stripes. The flowers rise above the foliage and have outer white petals with a golden area near the base and the inner petals are white, flecked with brown at the base. The inner most petal-like structures, called style branches are violet colored. Flowers year round in coastal southern California gardens with individual flower lasting only a few days and are quickly followed by new flowers. Flushes of flowers appear on roughly a two week cycle which has given this plant its common name of fortnight lily. The fortnight lily is very drought tolerant in shade but can also be grown in full sun with regular to occasional irrigation. Seems to bloom best with regular watering. A good container plant or used in mass plantings or as a solitary accent clump. Hardy to 15 degrees F. This selection is slightly smaller than other Dietes grandiflora varieties that we grow but most other aspects are similar - for more general information on it see Dietes grandiflora. It originated as a selection we made from our stock plants of the more common cream striped greener leafed selection that we list as Dietes grandiflora 'Variegata' from which it differs in being a slightly shorter plant with even grayer foliage and a whiter variegation. We also grow Dietes grandiflora 'Sunstripe' that has green leaves striped with yellow.  This information is based on research conducted about this plant in our nursery library and from reliable online sources. We also take into consideration observations of it in our nursery of crops, as well as of plants growing in the nursery's garden and those in other gardens we have visited. We will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Dietes grandiflora 'Gray Ghost'.
