Cut flowers from Invasive Bull Thistle!

Presented by City of Flagstaff Open Space Program at Thorpe Park, Flagstaff AZ

Sep 19 2023
Cut flowers from Invasive Bull Thistle!

There’s a patch of Bull Thistle on Observatory Mesa we’d like to keep from spreading, come join us!

Bull Thistle, a gnarly, non-native, invasive plant, is happy in a patch on Observatory Mesa. Help us cut off the flowers and bag them, so that they do not go to seed and make the problem hugely worse next year. We'll meet at Thorpe Park Dog Park and carpool from there; it will be about a half-mile hike in. Wear sturdy shoes, long pants, long-sleeved shirts, a sunhat, and sunscreen. Bring drinking water for yourself, and clippers and work gloves if you have them, but we'll have extras!
