Stems that form below the graft often sap energy from the blooms that the plant was grafted to have. Can be exciting, but keep an eye on those lower stems, and prune hard so that they will behave.
Sorry about the sideways photo, I don't know how to rotate! This plant was one of the first "yellow" blooming plant on the market, only a few years ago. The blooms look white! haha. The big curved stem has the reddish pink flowers that are not in any way remarkable. But all that energy has been taken away from the white part. I will graft the white onto that stem eventually, if I am ever successful at grafting!! Grrrr, I keep trying, don't know what I'm doing wrong. Owell!!
.This is my last effort at grafting,, the bottom is laughing at me! Two sprouts from the stem, and the scion is toast. GRRRRRR!!!! (this is another plant with the same problem of an unwanted limb)
