Dahlia 'Chimborazo', mid July. "Fittingly named after an Ecuadorian volcano, this is a tall and graceful collarette dahlia with exotic bi-coloured flowers made up of discs of broad outer ray petals, rich carmine red in colour, and elegantly twisted at the tip. These are brought blazingly to life with an inner collar of numerous smaller, vibrant yellow rays. The effect is light but striking, with the flowers carried at and above head height on naked stems...Bred in 1959 by J. Crutchfield." [Fergus Garrett, Great Dixter]
