Verbena bonanseris cuttings - can they go out into the border?
I took loads of cuttings from my verbena bonanseris plants over the summer (I find this a much easier way to propogate than sowing seed). They've been romping away and some of the 15cm pots they are in have roots coming through the base. The tallest cuttings are now about a foot high. Is it OK to transplant them out to the border now, to over-winter in situ, or are they best kept in the cold frame/unheated GH over winter for a spring planting? Thanks for any advice you can give.
