Each year of multipication plays a big part as well.,.I have been lucky to sit back and watch 'Silk Road' year after year,also, Starburst Sensation, and Nymph,...They all have their own traits.,,but, , as Rick explained above' climate, culture[and Im going to add another one], care-seem to influence results,.I know sometimes I am lazy, and because of the quantity of pots/lifes demands/ weather fluctuations I do leave a few to 'fry'-There is just nowhere else to put them [ in a choc-o-blok] lily garden[of pots]
