I needed to research which of my plants would be ok in acid soil for one of my customers and it seemed daft not to document the findings. In addition to rosybee plants, the top acid soil plant for bees has to be heather. Beware of rhododendrons as, even though the bees are quite happy on them, the resulting honey is toxic. Try buddleia as an alternative if you want a large shrub.
The following plants will be tolerant of acid soil up to a ph of about 6.
- Aster (actually prefer slightly acid soil)
- Papaver (poppy)
