An Anemone Robustissima question
This past spring I purchased 1 of these plants from Bluestone as kind of an experiment to see how well it would do in a particular location. From a 3 inch pot, I now have a plant about 15 inches across (foliage mass) about to bloom. It grew well.
In fact, now that I've seen how well it has done I want more next year. So the question is: How do these multiply and how fast? Could I safely assume this one could be divided next spring or will it spread out on its own? Or should I just plan on ordering some more plants next spring? I think I would like to devote a whole bunch of space in this bed to anemones.
