Subject: P.villosa - difficult!

Dear Filippo,

I once managed to grow one plant from seed from the UKCPS - the seed was
donated by a Norwegian member of the society. The plant grew well
during the summer but died in the autumn without forming a hibernacula.

It is perhaps worth considering that day length may also be an important
factor. The plant will have a short growing season and very long day
length during mid summer. However I may have failed with this plant as
rapidly shortening day lengths in late summer/early autumn may be
necessary to induce hibernacula formation. Thus in order to succesfully
grow this species you may need to artificially control the day length as
well as temperature.



PS - a belated thanks for the seed and I hope the P.vallisneriifolia are
still growing well for you.
