Fabulous, rich velvety-maroon-to-almost-black, chocolate-scented flowers open over a very long period from early summer right into the frosts of autumn. Amazed growers cannot resist smelling this wonderful perfume which comes from a chemical constituent very similar to vanilla! Although available for many years as sterile plants, viable seeds have never been produced, but after a spontaneous mutation occurred, one plant was discovered with just a few fertile seeds, and plants grown from these seeds will also produce a small number of fertile seeds. Incredibly, these plants vary in stature and colour of flower, some being very dark, almost black, as illustrated! Mature plants vary from tight compact clumps with short-stemmed blooms, up to large branching beauties with very long stemmed flowers which are ideal for cutting. Flowers range from small to opulently-large, whilst the fragrant petals vary from notched or feathered to oval and entire, as shown in the picture. Just a few named clones currently exist, one of which is known in the trade as 'Chocamocha' a beautiful, top-selling dwarf form of this plant which has redder petals than many of the forms these seeds will produce. Originally from Mexico, this rare and lovely plant is now described as extinct in the wild, but you now have the opportunity to grow your own new variety. We collect laboriously and one at a time, just a small limited number of good fertile seeds of this legendary and incredibly valuable plant, hence the very high price.
Sowing advice: For best results, sow seeds onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and although germination can be quicker if kept at 15 to 20 degrees C, we sow most seeds in an unheated greenhouse and wait for natural germination as many seeds wait for spring before emerging regardless of when they are sown. Spring sowing will obviously give them a full season of growth. Once pricked out into small pots keep them warmer. Plant finally in a well-drained sheltered spot or a large pot.
