Everything is doing well but later than normal. First pic is of the species single of '09.
Species double of '12. I pinched off the blossom once it bloomed to verify correctness. One should always pinch off the buds from a new peony so more nutrients can be stored in the roots. (or that is what I read)
Ssp. lithophile of '12. It had 2 small buds which I pinched off.
Early Scout 0f '09. Not a fern leaf but a very popular hybrid with a fern leaf.
As far as root size goes, buy from a respected grower and trust their judgement. The P.tenuifolia purchased in '09 had 3 eyes, 2 of which were on stringy stolons which are not typical of regular peonies. As the pic indicates, it is now doing quite well. BEWARE OF THE CRAP LISTED ON E-BAY OR PERSONAL INTERNET SITES. I think one can trust any individuals on this forum. I choose not to sell since the possible problems outweigh any profits.
