Thanks everyone. Nice photo lilylouise
I popped to my local garden centre today and they had them on offer, 7 for £10, so I bought 7 .
How large do they spread? And how quickly do they spread? I have 4 planters that Im going to put them in, each planter is about 12" x 12" square. Sould I just put a couple in each and see what happens, or should I cram more in?
