Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

Iris graminea L.

Rhizomatous Iris with usually 4 long, slender leaves, longer than the flowers, and a terminal inflorescence of 1-2 flowers, lilac-purple, the falls flushed white, veined with purple.  [RHSD, Hortus].

Horticultural & Botanical History

‘The flowers expand in June and have a scent something like that of fresh plums.  A native of Austria, perfectly hardy, and will grow in any situation.  Our drawing was taken at the Nursery of Meffrs. Whitley and Co. Brompton.  Cultivated here by Gerarde, in 1597.’  [BM t.681/1803].

History at Camden Park

Iris graminea is marked with a ‘c’ in an 1836 edition of Loddiges’ catalogue held at Camden Park [CPA].  In William Macarthur’s code, used and explained elsewhere, this means grown at Camden.  It is almost certain that it was grown in the gardens around this time but may have been short lived as it did not appear in the catalogues.


Iris graminea Thunb. (1784) = Iris ensata Thunb. which see.
