#Agastache kudos mandarin full#
Reaching about 50cm (20in) in height when in full flower, and branching well from the base, the plants are hardier than previous varieties of this type and, perhaps more importantly, are more tolerant of cold, wet winter soil. More recently the focus has turned to the shorter, more drought-tolerant types derived from species native to California and Mexico, with large flowers often in fiery shades.īoth groups give us colourful spikes of flowers and aromatic foliage, but it is in this second group that most of the development is now taking place: extending the range of colours and increasing the hardiness and drought tolerance being the main targets of the plant breeders. You can see them in the Piet Oudolf-inspired borders at RHS Garden Wisley. At first it was those varieties popularised by garden designer Piet Oudolf, the tall hardy perennial types from Asia and northern parts of North America, most often with blue and purple flowers.
