Dietes grandiflora N.E.Br., J. Linn. Soc., Bot. 48: 35 1928. ;
.
Common name: Wild Iris, Fairy Iris, Butterfly Iris
.
Dietes grandiflora (large wild iris, fairy iris) is a rhozomatous perennial plant with long, rigid, sword-like green leaves belonging to the Iridaceae family. This species is common in horticulture in its native South Africa, where it is often used in public gardens, beautification of commercial premises and along roadsides. The blooms are white marked with yellow and violet. Dark markings are found at the base of the outer tepals. These are borne in abundance during summer, especially after rain. Flowers are followed by 5 cm long green capsules that contain very dark brown seeds, these are dispersed when the capsule splits open.
Plants prefer dappled shade to full sun where they will flower in profusion, though they will grow in shaded areas (with an accompanying loss of flower production). Under favourable conditions, the clumps multiply rapidly. Dietes grandiflora are drought and frost hardy, making them popular for en masse plantings.

Flowers seen In Los Angeles and Sacramento, in the first week of Oct. Is this Dietes iridioides or Dietes grandiflora?
Kindly validate between the two Species. http://southeastgarden The only difference I could detect in so many years is the flower size: less than 6 cm in D. iridioides, 8-10 cm across in D. grandiflora. Thank for your feedback. Yes …
Another Dietes from California: Dietes iridioides:
Another species of Dietes, D. iridioides (L.) Sweet (syn: D. vegeta (L.) N E Br.), commonly grown in California. Hope we find this one also in India. Common English names: African iris, Cape iris, Fortnight lily, Morea iris, Wild iris – These flowers just look awesome. I also happened to see them in many household gardens in bay area in Aug 2010 I feel it may be Dietes grandiflora (Cultivated) as per discussions in another thread: Dietes Species For Validation : California : 24NOV14 : AK-59 as well as per differences at http://www.pacificbulbsociety.org/pbswiki/index.php/Dietes
Iris for Common & Botanical ID: I do not know if this has another common name.
Would appreciate Bot ID too. Pics taken March – April 2011 in Los Altos, California.
Dietes iridioides African Iris, Morea Iris, Fortnight Lily. Yes .. Very common in California. When I first saw I thought it to be some species of Iris, till I identified it correctly as Dietes iridioides. not an iris, used to be classified as lily… now though I do not know grows profusely and as volunteer even in sandy coral based soil of florida…. I didn’t understand your comments: When I first saw I thought it to be some species of Iris, till I identified it correctly as Dietes iridioides. Do you mean to say that the genus is different than Iris?
I always thought that the members of Iridaceae family are called as Iris as common plant name. The above plant does belong to Family : Iridaceae as per Wikipedia and GRIN. Would like to learn something from you Iris and Dietes are two different genera. In Iris the perianth are joined into a tube whereas they are free in Dietes and genus Morrea, in which, however rhizome is absent. All three belong to Iridaceae. I feel it may be Dietes grandiflora (Cultivated) as per discussions in another thread: Dietes Species For Validation : California : 24NOV14 : AK-59 as well as per differences at http://www.pacificbulbsociety.org/pbswiki/index.php/Dietes
