When I Googled this: Bugle Weed - Ajuga Burgundy Glow (Glow", not "Gloo")
I found three eBay vendors, three other vendors, and Hirt's Nursery. I never recomend Hirt's Nursery.
I think those were all for plants, not seeds. Do you think these are sold anywhere as seeds? I think they are hybrids multiplied by dividing the rootball or by cuttings.
"USPP#18805: unlicensed propagation prohibited. Registered with COPF."
Maybe the Canadian Ornamental Plant Foundation.?
Check the ATP Plant database, I see several members have plants, and might share seeds even if the seeds will not come true to the parents.:
Bugleweed (Ajuga reptans 'Burgundy Glow') (3 members)
Bugleweed (Ajuga reptans 'Toffee Chip') (1 member)
Bugleweed (Ajuga reptans Chocolate Chip)
http://garden.org/lists/plant/...
From the ATP Plant Database:
Chocolate-Chip Other info: Does not produce seeds
You might also try Googling Ajuga reptans Burgundy Glow, and/or Bugleweed. Googling Ajuga reptans Toffee Chip (Chip, not "Hip") gave several descriptions but no vendors were in the first few links I checked.
I suggest Googling for sources of plants.
