Not done well this year-in pots, but very slow to flower and palnts still small-could be to do with hot summer.

The plug plants and seedlings are of the very best quality, and save you having to sow, prick out and grow on plants when you only want a few of each variety. They also eliminate the risk of possibly having to manage without certain strains that are either slow or erratic to germinate, as by the time those fail it's then often too late to resow.
The customer service is also second to none.
