Q: I have two questions about wisteria with which I hope you can help me.  I purchased a wisteria a few years ago.  It has white blooms.  It bloomed the first year I planted it.  The second year it had no blooms and last year it had only two blooms.  The vine looks very healthy and is growing well, but virtually no blooms?  I live in northern Maryland zone 6 to 5.  Do you have any idea why I might not have blooms?

My second question has to do with whether or not wisteria is poisonous.  I read that it was part of the pea family and that typically would mean it is poisonous to horses.  The plant is in reach of my horses and one of them did some selected pruning last year but did not show any side effects.  Wisteria was not listed in my poisonous plant book, so I’m unsure of whether or not it is a danger to the horses.

Thanks for you help with this.
