A customer has just brought these in, asking us if we know what is
wrong! It's supposed to be Madame Isaac Pereire. Apparently every
flower, bar one, is like this. All they have done is feed it last
September with a ready-prepared solution so no incorrect mixing or
dilution is involved. They say neither they nor their only neighbour
have used any sprays or weed killers. If anyone recognises these
symptoms and can put a name to them, we'd be very grateful. I've
promised them that someone will have an answer for them!

We get this from time to time on the very double roses, I have always
associated it with cold while buds are forming but have no idea if that
is correct

It's one of the suggested causes at Missouri botanic research, and
someone else has suggested capsid bug while another has suggested
Proliferation. http://apps.rhs.org.uk/advicesearch/...e.aspx?pid=634
for which there seems to be no satisfactory explanation.
Given the spring we had, cold is certainly an entirely possible
suggestion and I only wonder why we didn't all get that problem! I must
check where they live and see if it's likely to be much colder than we
had here. A late frost is certainly a suggested cause.
