I mentioned a while ago that Utricularia dichotoma seems to respond very well
to cold treatment to induce flowering. At present, only one of the two forms
in the greenhouse has flower stalks (two), whereas those in the mini peat-bog
have dozens (both forms). I think I'll put the potted plants out next winter
to see if it really works...
Barry - planted your D. intermedia seeds today. No sign of life yet - sure
they're not duds? ;-)
Also potted up the 8 new Utrics. and the Drosophyllum seeds (we're
trying the "Slack-pot" method). The U. graminifolium accidently lost
its biggest flower stalk (about 7 flower buds) :-( Apart from being a
bit squashed, the plants seem to be in reasonable condition. Has anyone
heard of a U. longifolia "miniature form"? (I thought that it might
have been U. calcifida mislabelled, but Fred offered us some of this
too... Maybe its U. alpina :-) )

The blue flowered one could be var. forgetiana (I forget the correct
spelling, but it *really* is something like forgetiana!), which is
mentioned in Slack's second book. It also says the longifolia is a
variable species.

Well, our (normal?) longifolia has had trouble with large purple/red
blotches on the leaves, which I discovered had fungi/mould on them.
I've sprayed it with benlate (a rather old mix, but anyway...) and
hopefully this will fix it.
