Horticultural & Botanical History

‘When well grown and flowered this is one of the handsomest of the Allamandas, and it is not very difficult to manage’.  [Gard. Chron., 1855].  ‘A magnificent species, and one of the very best climbing plants.  The flowers are larger than those of the A. cathartica, being five inches across; and the tubular portion, which gradually widens to the mouth, is five inches long, and a much richer golden-yellow colour.’  [FC p.245/1847].  A. grandiflora was first discovered by Mr. Gardener whilst exploring the Brazils, and from seed supplied by him in 1836, it was reared in the Comely Bank Nursery, Edinburgh.  [MB p.79/1845].
