Gardeners' Notes:

Positive irishmist On Jul 17, 2013, irishmist from Rochester, NY (Zone 6a) wrote:

This has grown well and bloomed beautifully in my Zone 6A for 5-6 years. Just started to bloom on 7/14 and now instead of solid panicles, the spray consists of smaller tufts of flowers along the panicle's stem which increase in size from the tip to the central branch. It looks like the yellow buddleia (Honeycomb I think). Anyone know what caused this change. Weather was very rainy for several weeks then hot and humid during flower formation. Related?

I have been growing buddleja davidii in Maryland for 20 years and have never had a volunteer seedling. Japanese barberry is very invasive in the woods here though, and porcelain berry vine is a nightmare.

Negative Patmisty1 On Jul 28, 2011, Patmisty1 from College Park, MD wrote:

This plant is beautiful but needs to be deadheaded and not allowed to go to seed. It is invasive in many states and crowds out native species. Maryland is one of the states that has it listed as invasive and to be removed from the wild. Please check with your extension service to see if it is a problem in your state.

I grew Buddleia davidii [not sure which one] several years ago, about 1995-2004 in California, Maryland. It grew well with little attention. Recommendations at that time were to cut it back in late March, early April. Sometimes that didn't happen, but it surely did attract butterflies and bees, regardless. I say it grew until 2004. It might be growing still. That is when I moved to Maine.
Today I found the plant again.
While the hang tag says to zone 5, I'm going to try it in zone 4.
Hopefully, I will remember to report back to you next year on my Maine experience with Buddleia davidii "Royal Red."

I have 3 of these bushes growing as understory plantings in a dry windy bed under Maples. They grow and bloom very well there.

I do have this one plus Nanho blue and Nanho pink and definitly, it is the best fragrance of all!

Neutral smiln32 On Nov 25, 2004, smiln32 from Oklahoma City, OK (Zone 7a) wrote:

This variety is a 1928 hybrid from Good and Reese Nursery in Ohio. It's really not "red", but more of a deep scarlet or bright violet.

Most butterfly bushes are hardy in zones 5 - 9. If you live in zone 5 or a colder zone, the tops in your butterfly bushes will likely die back over the winter. Even so, they will come back the next growing season bigger and better then before. Butterfly bushes prefer full sun (they must receive eight or more hours of sun a day to thrive).
