I have a large clump of Moonbeam Coreopsis right outside my front door, and seeing it always makes me feel sunny. The bees and butterflies seem to love it too. Everytime I step outside I find bees and butterflies hovering around the blooms.
Any plant that attracts honey bees and butterflies to my garden is automatically a favorite.
I got a start of coreopsis several years ago from my mom. It’s a plant that tends to sprawl and can get out of hand if you don’t keep it in check by pulling out the plants you don’t want in the Spring.
It’s not a difficult plant to keep in control, it just seems to add to its growing area a little each year. You might have different results in your area, so check with local gardeners if your concerned it may be invasive.
It’s worth the trouble of keeping in check. If you’re thinking about adding Moonbeam Coreopsis to your garden, check with friends and neighbors to see if they have a start they’d like to give away.
I’ve also heard Moonbeam Coreopsis called Threadleaf Coreopsis, Tick Weed, and Tick Seed.

I enjoy Tickweed
also, it’s one of my favorites.
I have some blooming this year, too. I don’t remember planting it , though (gardening alzheimer’s???)
