I have a sizable brush pile in my yard, 5m x 5m (16ft x 16ft), height 2m (6.5ft). Even a colony of sparrows lives in it. I toy with the idea of planting a Lonicera caprifolium (https://en.m.wikipedia.org/wiki/Lonicera_caprifolium) just beside the pile, and hopefully, in several years, having a small hill of flowers and beautiful fragrance in summer nights.
It this doable? Would sparrows stay? Are there other hidden downsides?
EDIT: I now realized that Lonicera caprifolium is not fully evergreen in my climate, perhaps I should opt for evergreen Lonicera henryi, to protect birds during winter.
You can see my brush pile here, behind two weeping mulberries and a pile of logs:
