We've just had our first delivery of 1 litre perennials, 24 well known and loved varieties to choose from at a great value price of £2.99 each or 4 for £10. Grown outside, these plants are hardy enough to be planted now.

Perennials are best planted in the first half of the year to allow them time to get their roots established before the winter sets in, and from personal experience, I can tell you that they really bulk up when planted early, so as by late summer, you usually end up with plants more than twice the size of when you bought them!
