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.

The first one is a redbud tree, Cercis canadensis. Number two - that is incredible, I've not seen anything like it. Where is this located (city,state)? Are the leaves really silver colored? Otherwise it reminds me a bit in structure of wax myrtle. Number 3 is a wild Rubus, something like blackberry. Four, I am not sure, what does the foliage look like? Five looks like a Baptisia, as does #6.

Capable of forming rather large patches. One of my favorite woodland natives. +oM

wow! thanks everyone! #2 is definitely not hosta, because my "darling" deer would be all over them! ;-). I will watch to see of they flower, hadn't ever heard of Canadian Lilly of the Valley... Will also watch the other leaves for flowers.....Asters are native to the area. Gardenweb to the rescue, again! ;-). Thank you!
