Very pretty pics! I love columbine and you have some very nice ones. As to volunteers I don't immediately recognize I usually let them flower, then pull if they are a noxious weed. I move a lot of small volunteers every spring, pot them up, or compost, depends on which plant and how tolerant I feel at the moment. Right now I still have dozens of plants and seedlings I've potted up waiting for their place. However, a lot of lamb's ears, feverfew, shasta, and even a few columbine seedlings have been composted this year as I am seriously editing my garden. I'm also giving away a lot but allowing self-seeding can lead to chaos.

Identification of grasses can be very challenging. It usually requires close examination of the flowers, although some of the more common native prairie grasses can be identified pretty readily once you know what the overall appearance. A good starter book for grasses and grass-like plants is "Field Guide to the Grasses, Sedges and Rushes of the United States" by Edward Knobel. No photos, just illustrations and it doesn't distinguish between natives and non-natives. For other plants, something like Peterson's "A Field Guide to Wildflowers : Northeastern and North-Central North America" would be a convenient reference and it does mention which ones have been introduced.

Hi orcascove - I thought I'd chirp in and add a couple of additional aspects to your initial inquiry for clarification... Ipomoea quamoclit is available in several colors including red,pink,white and pink with a reddish star...

Thank you everyone!! I have most of it pulled out around the plants and will use the newspaper/cardboard/mulch method in the larger area with no veggie plants in it yet. I'm also going to check out the Soil, Compost, & Mulch forum. So, this fall, after all the veggie plants are dead and gone, is there something I should do to prepare for next year?
