Climbers in native hedge
Last winter I planted a mixed native hedge - mostly hawthorn - and I'd like to add something to extend the flowering period into the summer. At the moment the plant that's expected to flower last is the dog rose which I think should flower in June, although the hedge didn't really flower last year at all.
I'd prefer if possible to stick with native plants in the hedge, so I've been wondering about honeysuckle, which I'm sure I've often seen in hedges. However the information I've read says that UK native honeysuckle (Lonicera periclymenum) grows to 8m high. I have seen that it can be pruned to fit a hedge, but I'm wondering how much work that will be in the long term and if I'll regret it! I'm planning to grow the hedge to about 2m high, and it's about 2.5m long running north to south, facing west into the garden. I was thinking of planting the honeysuckle at the north end so it would grow through the hedge towards the sun, and if it could be trained to grow horizontally beyond the end of the hedge I could extend it onto a trellis where the space is too narrow for a full hedge.
Any other planting suggestions are welcome, with bonus points if they are native plants. However space is limited for multiple plantings because the hedge is in a raised bed against a wall and many of the spaces between the hedge trees have just been filled with crocuses!
