Good germination (had poor results from dwarf white a few years ago).
I have some in pots, some in a border and all are in flower. Good strong colours.

Excellent germination - I sowed undercover and some were up in just 2 days. Tall healthy plants that are flowering profusely and have been for weeks.

I only started using Sarah Raven products this year and I have no complaints whatsoever. The plants arrive in good condition and are well packaged. I shall continue to buy plants from Sarah and hope the good service continues. I thoroughly recommend.

These were decent plugs, and have performed well. I hadn’t appreciated the difference in height and flower size.
