clausa , more information


As I said before H clausa is not a wild plant in the sense that you 
will find a locality somewhere ( Chung could not find any) It is a 
plant once found in the wild and now found in many gardens. Not 
being really wild there are no insects that can fertilize the closed 
flowers as it is a triploid and most triploids are largely sterile.
If I find that there is less than 5 % good pollen  the chances of 
getting any offspring seem remote.  This figure of 5 % is 
independend wether you measure that in the garden or on any 
plant in the wild. Still the more people try the more chances there 
are that one may succeed, but why use it instead of the var 
normalis?Yes indeed any time you see that a cv is a hybrid with 
clausa , it is most likely a hybrid with the var normalis.
By the way it is not suited for pot culture, as it soon will refuse to 
flower.
