Senecio confusus aka Mexican Flame Vine

[sweetscent]

I purchased this plant @ the GFWHS plant sale in May 2005 & planted it approx 1 wk later. It has spread well up a section of chain link, but except for the 4-7 blooms it had on it when I bought it, it has shown no desire to bloom since then. All the sites claim that it blooms til fall, either continuously or in successive flushes. I have fertilized w/ earthworm castings, kept the roots well mulched, & have seen NO sign of pests, yet the silly thing refuses to bloom. I've also tried stressing it slightly by cutting back on water, but it just sulks & droops til I give in. Any info appreciated. Also, can I dig it up to transplant, or am I better off trying to start new plants w/ cuttings, since I have no seeds. Thanks!
