- Butterfly bush cultivars do not seed invasively- in Minnesota we have not had any seedlings pop up in five years of growing
- No serious pest issues
- Deadheading required for optimal blooms and to control potential seeding. If you can’t/won’t deadhead, seek out an alternative plant solution.
- Japanese beetles eat some of the blooms. If there are too many, we flick them into a bucket of soapy water. They usually prefer eating fruits and vegetables though…
- Butterfly buses are not host plants for caterpillars…True! This is why our garden isn’t planted with 100% butterfly bushes. We also plant milkweed and host plants for other native wildlife. There is room for both in many gardens. Why do so many choose to harass home gardeners with ridiculous (and unnecessary) native ultimatums?
Liatris ligulistylis is a popular late-summer native for butterflies that is not a host plant for caterpillars. Should we dig out all our liatris and only plant milkweed?
- Only a few pollinators will use butterfly bush? This is simply not true. I see many different pollinators on butterfly bushes and it supports butterflies, moths, hummingbirds, and many other smallinators. If you don’t have experience growing butterfly bush and refuse to try on native principle, how do you really know if you are spreading reliable information to others?
There’s a difference between sharing reliable information, and spreading irrational fear…
- Butterfly bush is on an invasive species list: yes, specific varieties in specific regions like the Pacific Northwest.
- Buddleia cultivars are designed to be non-invasive and some are even sterile.
Here is some reliable info about the potential problems surrounding Buddleia.
Buddleja Buzz Growing Tips:
- USDA hardiness zones 4-5 should leaf mulch in fall for plant insurance
- Plant buzz in spring or fall
- Prune to 6″-12″ when new growth starts to emerge in spring
- Grow in Large pots to bring the butterflies in for patio or window viewing
- Attract more pollinators by growing in full sun
- All non-native plants should be grown in a controlled garden setting when they can be monitored for potential issues.
- Cut- deadhead spent blooms to promote new flowers. If you don’t deadhead, butterfly bushes probably aren’t a good option for your garden.
Buddleja buzz is also a popular nectar source for bumble bees, hummingbird moths, hummingbirds, red admirals, red spotted purples, skippers, tiger swallowtails, and many other pollinators!
