These seedlings were planted out and flowered briefly, and I stress briefly, then proceeded to get very tall and bushy. I would not have this plant again due to its very short flowering season.

Again this was another Sarah Raven recommendation which persuaded me to buy this plant. Disappointing results. One large flower head, but not very colourful and although there appear to be more "buds" they are not opening so the flowering time of these plants were very short lived.

Service great, but not so the collomia. Very disappointing. Very short flowering period, horribly sticky to handle, plants deteriorated very quickly. Got very little out of them for cut flowers. Not one I’ll be buying again....

These are very pretty, but as we have had very little rain this summer, some have suffered. I now wish I had put them into pots.
The service I receive is always excellent.

Nicotiana look wonderful despite one got decapitated by the slugs.
Collomia: not very exciting
Teuthonia arrived very spindly, but are now fine.(first lot did not survive the journey)
Rozanne coming on despite being a bit overshadowed.
5th: can't remember
