Thanks Leena and Gail.
@Leena: That would be great, if you could send me in autumn some seeds of your P. veitchii; thanks.
I have clay in my garden and for me it looked like that is the reason why P. veitchii is not doing well here. It was more or less in full sun, but I would like to try in future in semi-shade and in a mixture of clay and compost earth; hopefully it would like this more.
The P. emodi shows no sign of botrytis (I have anyhow only few locations where I can see probably some botrytis damage, as normally I eliminate the dead material of the Peonies). The flower buds of P. emodi actually do not shrivel or get brown for very long; they just stay at the same size for months and green. I try this year to fertilize more (I actually did not fertilize in the past years, but there are about 8 stems, so a real mature plant).
It is always surprising that some people have problems with some plants while others do not have them, but they have problems with other plants which others (i.e. the some people) do not have. It is probably a kind of mixture of environment (earth, temperature, nutrients, water, sun) and care of the garden owner. Most of the environment one can influence by changing place or earth, watering or fertilizing. The care one certainly can change, but strangely, the more and care the less some plants like it.
Does anybody of you know the name of the following cultivar (I got it under the name of 'Quing Long Wo Mo Chi'); the flowers are most time double, but sometimes also only semi-double as seen on one of the 2 pictures? The plant itself only gets to a height of around 40cm, but I really like the flowers especially when they are only semi-double.
