I have a very narrow front garden border that I planted lots of bulbs (in a fairly haphazard, un-ordered way!) two winters ago. I had a baby last year and didn't really get much gardening or maintenance done. This spring most of the bulbs, except Narcissus 'thalia', aren't doing well at all - I can see lots of foliage but none seem to have any flowers coming.
So, I think the border is just not deep enough for most of them. I think this autumn I'll dig them all up and just plant Thalia all the way down the border. Is there anything I can plant with them, that might give a bit of interest at another time of year, that would look nice and cope with the not deep / narrow border? Ideally I'd like to plant en masse. The top part of the border is constantly in shade and the bottom two thirds do get some sun. Thanks in advance for any ideas you might have!
