I got a good sized healthy dend x delicatum in the fall last year. It started spiking a few weeks back. The spikes are still fairly young. I was checking up on it yesterday and found two new canes had started to grow. At no point has this plant stopped throwing out new roots. Is it abnormal for this particular dend to simultaneously spike and grow new canes? I was under the impression that it would have a nice long winter rest, then flower, then grow new canes.
