From the text of Paxton’s Flower Garden, 1853:
“. . . it is a hybrid produced from Aeschynanthus speciosus impregnated with A. grandiflorus, and possess the brilliancy of colour and hardy consitution of the male, whilst it also partakes of the many good qualities of the other parent.
It is easily cultivated, producing a long succession of large umbels of brilliant coloured flowers, and requires much less heat than many other Aeschynanths. . .”
