Buddleia progress report.

Buddleia globosa hybrid

Buddleia X Peach Cobbler

The B. globosa hybrid blooms in Spring.  It was purchased as a 6 inch start.  Lots of growth.  Not as much as the others, but it was smaller.  Expect flowers next Spring.

The Flutterby series Buddleias grew fastest.  The flowers were the largest, but also the messiest.  Bumblebees liked them  There were also a few butterflies.  Those were "Peach Cobbler" and "Blueberry cobbler".
Buddleia X "Blue Chip"

Buddleia X "Blue Chip"
Another Flutterby series hybrid, but dwarf, was "Blue Chip".  I had that in a weedy iris bed that went unwatered until fall.  It did remain small.  The flowers were very nice.  I sort of regret not taking better care of it, but it bloomed and should be fine next year.

Buddleia X "Miss Ruby".  The remaining Buddleia hybrids were "Miss Ruby" and "Miss Molly".  Those were neater.  Growth was not as rampant.  The flowers lasted longer and were more vivid, compared to the Flutterby series.  The flowers were smaller, which is beneficial.  The much larger flower panicles of "Peach Cobbler" and "Blueberry Cobbler" start turning brown at the base before the tips open.  So with those, I either have to tolerate brown dried out flowers, or deadhead before they are done.  Bumblebees and a rare honeybee foraged "Miss Molly" and "Miss Ruby".

From the State of Oregon Department of Agriculture site, the following Buddleia varieties have been tested for non-invasiveness and are allowed.  It costs the grower $10,000 to have a variety tested at OSU, and takes 18 months.  If the grower already has data proving their variety is noninvasive or proving it is an interspecific hybrid, the cost is $150.00 per hour for the state to evaluate the data.  So, it seems wrong for anyone to grow these by cuttings.

A few weeks ago I say one local nursery carried "Black Knight" - a pretty but invasive and illegal variety.  I did not buy it.

Non-Regulated Interspecific Cultivars

These listed cultivars have been proven to be interspecific hybrids through testing and laboratory analysis. They are not regulated under Oregon's noxious weed quarantine and can be transported, propagated, and sold within Oregon. The fertility of these cultivars has not been assessed, though interspecific hybrids generally exhibit low fertility.
Buddleja 'Lilac Chip'
Buddleja 'Miss Molly'
Buddleja 'Miss Ruby

File:Buddleja matico recht.JPGThis is Buddleia globosa, pic via wikipedia.orgB globosa is not regulated, because it is not invasive.  B. globosa may be more attractive to bees, but blooms in spring or early summer.  The B. davidii and interspecific hybrids bloom later summer and fall.
