Blue Devil Echium vulgare

currently designated "noxious"

- A common sight in South-western AB but I have only found one isolated occurance in Central AB (probably brought in on railway maintenece equipment). With a coordinated regional approach, it may be possible to keep it contained in the south. --Tony Blake 23:20, 17 April 2009 (CDT)

Not in ANHIC. USDA shows in USA (CA, CO, FL, IA, IL, KS, MN, MO, MS, NE, OR, PA, WI). Allison says "Annual grass (Poaceae), native to e. Asia and introduced in the USA. There is detailed Canadian range and biology information available (Darbyshire et al., 2003). In Canada, the only known population in southern QC is undergoing eradication."

HI Jim. Just received an e-mail from the Canadian Weed Science Society. They want wooly cupgrass listed as a restricted pest. Maybe we could add that one to the restricted list here in Alberta. From Harry Brook. Posted by Jim Broatch

Cypress Spurge Euphorbia cyparissias

Natureserve I-Rank: High/Low

• I've never heard of this as a serious problem in AB (Alec). (Nor have we, ANPC via Jim)
• I have only seen it in flowerbeds in the Peace Region where we require it to be controlled. Aggressive and difficult to kill, a concern (in my mind) due to the potential for the milky sap to cause temporary or permanent blindness. Education and awareness suffices, remove from NOX. Normand Boulet
