Recently, on another, non-gardening, newsgroup, I mentioned that I was going
to plant a clematis. Another poster commented that they are poisonous.
I've never heard this before, are they right?

There are more poisonous than non-toxic plants in every garden.
Daffodil bulbs are poisonous, rhubarb leaves are poisonous, all parts
of laburnum are poisonous. Euphorbia sap can produce a major skin
irritant for some people as can daffodil flower stem sap and so on. It
might be worth looking at the RHS web site but I don't think there has
been a fatality through anyone chomping on garden plants, for years. I
have never, ever, heard of anyone suffering from a reaction to Clematis.
