I'd really like to try and get our shady bed a bit sorted out this winter, and I wondered what people would suggest. We've got a long thin town garden, and it's a northeast wall, which gets quite a good bit of midday sun in the summer, but a lot less in the winter. Soil is still pretty rubbish (clayey, with bits of lime mortar that have fallen out of the walls) despite quite a lot of manure etc.
It's about 40 ft by 4-6ft, so a substantial size; the wall behind is about 4-5ft high. Currently we have a viburnum, with some rather sad hellebore under it; an foolish camellia (it flowers downwards, even after staking, so you don't get to see them much); an old passion flower, and then some elderly roses, a large clump of some kind of daisies, and rampant forget me not, aquilegia, evening primrose, poppies.
What would you suggest to give the bed good 'bones'? We need more foliage plants, and stuff that looks good at different times of the year.
Any good advice sites anyone can recommend?
Thank you!
