Fargesia robusta questions
Anybody else with experience with Fargesia robusta?
When is the best time to divide and transplant this species if it shoots in both early spring & late summer??? A couple of weeks ago I divided my clump, which has been in the ground for about 3 years. I moved half the clump, and left the other half in place with minimal disturbance (in case it doesn't take kindly to transplanting!). I knew I was taking a bit of a chance disturbing it this late in the growing season; fortunately the new shoots haven't leafed out much, so I hope it won't be stressed too much. The clump seems healthy and has been growing well, getting a bit taller every year (tallest shoots are now up to about 4-5 feet) so I was surprised to find that the root system was quite small and rather shallow. I'm starting to wonder if (a) this was a good time to move it after all, (b) it will survive the transplanting, and (c) if it was very healthy in the first place.
BTW a visitor who recently moved to the USA from France saw my F. robusta and commented that it did not look at all like the F. robusta he was familiar with; he said the leaves on mine were much too small. I thought of this again when I saw another Fargesia species (F. nitida, I think) in a garden and it looked almost identical to my plant. So... how do I know if I have the real thing or not?
