I just bought a cup plant (Silphinum perfoliatum) at the nursery today. The yellow flowers look like a cross between a daisey and and yellow sunflower. Bigger than a daisey flower but not too much bigger. Tag states native to US and seed heads attract Goldfinches. Grows 8-10 feet tall. I know this is a prairie flower but I have no meadow or prairie, just a small sunny spot where I am starting to put some tall grasses and bird attracting natural flowers. I have a Switchgraas there to start and will put the Silphinum there. Does this attract anything besides Goldfinches? I hope this is not a rampant spreader to take over the whole yard like some of the prairie sunflowers, which I have stayed away from.
I figgure Elaine from NJ probably has some of these growing in her meadow area.
