Detailed Information

Flower: composite shape
[photo of flower] 3 to 20 flower heads per plant, 1-inch across with short yellow petals around a yellow center disk. Round, curled bracts surrounding each flower exude a sticky resin.
Leaves: alternate attachment simple type
[photo of leaves] Thick, waxy leaves 1 to 2½ inches long with course teeth and often curled edges, generally oval with a pointed tip. Alternate attachment with no leaf stem.
Notes:
This plant is easily identified by its unusual bracts. With its thick leaves, it reminded me of a succulent. It looked rather out of place in the middle of a field, surrounded by dry grasses.

Please: Do not ask about controlling invasive species, are plants edible, where to buy seed or other gardening questions. I am not a horticulturist or botanist, just an enthusiastic hobbyist so I probably don't know the answer. Please check the links page for additional resources. -thanks much
