Often when varieties of plants are propagated some results are better than others....I call them clones but prob incorrect term. For example, talking about euphorbias....euphorbia rubra in this case I find one plant is reliably perennial whilst another "clone" is less robust and lasts just a couple of seasons. I now propagate from the better pant. Gary, maybe remove the would be flowering stems and leave the remaining ones to grow. So, I would feed well to encourage this new growth hopefully to flower well next spring
