this is the second year in a row that black locust, the main honey flow at our location, has been wiped out by a late frost. The average date when trees start growing in the spring has been moving back and the danger of late frosts has increased. The previous year's event was supposed to have a return period of 30 years and... Here we go again.
But the locusts are not even the worst hit. The really hard hit plants are the summer flowering "bee trees" - euodia, koelreutheria, sophora...
So this is the picture:
- it is exactly the summer-flowering trees that are the most sensitive to a late frost - they currently look like cooked spinach (and so do the locusts, of course).
- on the other hand there are bushes/trees which are very attractive to bees and apparently have frost-resistant flowers, at least to a sufficient degree - elaeagnus umbellata/multiflora was/is still being visited after two nights of freezing temps and last year they prouced a regular size crop of berries in the fall.
So, my question... Does anyone know of a shrub/tree that combines the two qualities, ie. it's summer-flowering, supplies honey and pollen AND can handle a spring frost without having to regrow the current year's vegetation from scratch?

I wonder about Jujube trees? I was recently told that the Jujube trees of a neighbor, withstands the late frosts and produces summer blooms. I thought of this topic when I was told that, and figured it may be worth sharing.
