The message
from Chris Hogg contains these words:

We've just spent a day at Tresco, a lovely sunny day and superb
gardens full of exotics. But does anyone know why they have such an
abysmal selection of plants for sale? I would have thought they would
have done a roaring trade and it would be well worth their while, let
alone reducing the risk of people being tempted to take the odd
cutting....

It must be a conscious decision on their part, but why?

Someone told me recently Tresco make £20,000 pa from their plant sales.

Janet.
