green_go - if a plant isn't native, you always run the risk of introducing something which may become invasive in your garden conditions. Once you factor in moisture, soil components and natural predators, it's always wisest to think twice before planting something unless experience has shown that it behaves in your garden. Certain native species can also run rampant when planted in areas where they aren't traditionally native. Have I erred when planting certain perennials after hints on this forum suggested they were invasive? Let me count the number of self-sown seedlings I've regretted. I've no experience with Filipendula since I've never been tempted to plant it. I just make certain I've done my homework before digging a planting hole or setting something in it. Not planting something has been my guide and = less regrets.

Funny, the flowers look something like what she planted last year but the foliage I have growing is nothing like the pic! I have buds on a few plants so maybe by weeks end I will have a flower I can take a picture of. thanks.

Yup - the flowering one is yarrow. Looks like a native one to me.

The white fuzzies in the top picture are rabbitfoot clover, Trifolium arvense. The little yellow flowers look like low hop clover, Trifolium campestre. The trifoliate leaf with whitish chevrons is red clover, Trifolium pratense. Great for adding nitrogen to the soil but not a native plant in the bunch.
