Aspen is the world's first frilly edged Zygocactus flower. Did you know it was named after Aspen in Colorado which is famous for it's snow. A rather fitting name don't you think.
Aspen belongs to a plant family now called Schlumbergera but in Australia they are still referred to under their old name of Zygocactus or plain old Zygos.
The breeder is the famous BL Cobia of Florida USA who chemically induced a mutation of another one of their varieties called Bridgeport which has large rounded petals.
Breeding was undertaken in the USA in the late 1980's with the mutation stabilised and then vegatively propagated to build up numbers all from one leaf segment which are called phylloclades. It was released in the USA in the early mid 1990's and released by Brindley's Nurseries in Australia in 1994 where it created a lot of interest. Aspen still turns heads today.
As you can see Aspen has an upright growth habit which makes it ideal for pots and even large pots without the need to find hanging space in a basket. The leaves or phylloclades are thicker than most other zygocactus varieties and it is this extra strength that supports the weight of the branches with flowers and buds.
Have you noticed the flowers are partially pink. It is not a new variety is is simply the effect of sudden temperature drops a few days before the buds open. It is even possible to have a combination of white and pink frilly flowers if the temperature is fluctuating a few days before each bud opens.
