I have it on my pulmonarias and lupins in the drier, full sun borders, elsewhere they are fine. Honeysuckle is OK. Teh only way to avoid is keep well watered in dry weather- water on an evening or early morning to prevent evaporation and use a mulch on those areas.
The honeysuckle will be fine -With the honeysuckle and pulmonaris once it has flowered- prune, which will get rid of the mildew and will give you better flowers next year or a second flush later in the year.
Just reminded me to go and shear my "frosted" pulmonarias and replant some in a shadier moister border!
