Louise, Ted Hooper's Guide to Bees and Honey has a garden plant list, at the end of ch.10 in the 4th edn. Berberis, cotoneaster, crocus, heathers, hebe, holly, hypericum, lavatera, shrub lonicera, mahonia, michaelmas daisies and other compositae, ribes, snowdrop, thyme, willow; his wild plant list is longer and includes quite a few gardenable ones e.g. bluebell, marjoram, field poppy, hazel, broom, soft & top fruits, hawthorn & of course ivy.
Your question makes me realise that I have some idea what my honeybees are using in the wild, and I record what bees use in my garden but don't distinguish bumbles & solitaries from honeybees. Must do that in future. Will you post your list?
