Horticultural & Botanical History

‘This is another newly discovered [species], which, like most of its kind, displays its beauties chiefly in the night.  It is the only one, as far as we yet know, that has white blossoms; these, when first expanded, are beautifully so, but in the morning they change to a purple colour, fade, and their place is supplied by a fresh succession. […] It was raised from seeds sent by Mr. Donn, from Cambridge; but was probably first introduced into this country from seeds sent to the Marchioness of Bute, by Prof. Ortega, of Madrid.’  [BM t.468/1800].  Introduced to Britain in 1796.  [PD].
