I bought 3 of these as little plants 3 years ago and planted them in pots. Year 2 they grew to about 2ft and were a delight to look at and also covered with butterflies. I pruned them as instructed and put them in a spare garden bed for the winter. In the spring I put 2 of them back in their pots and they have just started flowering but they are much bigger and a bit bare at the bottom. The one left in the garden has grown into a massive bush. When described as miniature bushes only hold true when contained in a pot?
