M&M's curse: Candy waste turns French honey electric blue, devastating beekeepers! 04/14/2026

for those of you who raise bees, here is an article of possible interest. enjoy DH

M&M's curse: Candy waste turns French honey electric blue, devastating beekeepers! It was a mystery unlike any other.

A lot of people mix these two up at first glance, and that’s exactly why I always tell people to slow down and check the stem before anything else.

Queen Anne’s lace and poison hemlock can look similar from a distance, especially once those white umbrella-shaped flowers open up.

But the stem usually gives it away.

What to check

Queen Anne’s lace
hairy stem

Poison hemlock
smooth stem with purple blotches

That one detail is a big deal.

The leaves and flowers can look close enough to confuse people, especially if you’re just doing a quick look while walking the yard, roadside, or edge of a field.

The root can look different too, but I would not rely on digging plants up unless you really know what you’re dealing with.

Around my area, I treat poison hemlock like a plant to avoid completely.
No touching bare-handed, no cutting it casually, and definitely no guessing.

If you’re not 100% sure, leave it alone and ask your local extension office or a trusted local plant expert.

That’s the safest move every time.

Have you ever spotted one of these growing near your yard or garden
