Helianthus pauciflorus--Stiff Sunflower/Beautiful Sunflower

I've ranted about them enough that they should get their own posts. lol Sunflowers have edible seeds, petals, and sometimes tubers, very young shoots, or young flowerheads. Some of them can be very aggressive.

Helianthus pauciflorus is not quite as aggressive H. nuttallii, though it does spread the same way and occasionally need their rhizomes pulled up.

All photos mine. All unedited.

I was quite sure both of the original plants (H. pauciflorus and H. nuttallii) were going to die so I planted them on either side of a relatively small area, but then neither of them died. lol The H. nuttallii definitely rules the roost, but H. pauciflorus still gets by.
