Conservatory Group

The Canna Conservatory Group consists of cultivars that have been raised specifically to satisfy the growing conditions in conservatories, or have been found to be suitable for that purpose.

CannaChesapeake

The growing conditions in a conservatory are quite specialised and do not suit many cultivars, this group have been selected for thriving in this environment, required features being plant vigour, early flowering, foliar appearance, self-cleaning ability and good propagation qualities.

 

CannaLenape

The originator of this group was Robert Armstrong (geneticist) while he was working at Longwood Gardens in the United States in 1967.

In 1907 and 1908 the RHS, at Wisley,  held Canna Trials both indoors in 1907 and outdoors in 1908. The differences between the two trials shows why specialist cultivars were considered desirable by Longwood gardens.
