Dandelion

We think this is a species of Taxacum although there are similar weeds, most developing foliage with jagged edges, daisy-like flowers and fuzzy seed heads that become more garden weeds. If you don’t want hundreds of seeds to develop, suggest you cut off at least the flowering head before the seeds disperse. Here’s a rundown on the Asteraceae family: http://www.wildflowers-and-weeds.com/Plant_Families/Asteraceae.htm The reason why we do not believe this is common groundsel, S. vulgaris, is that it bears tiny clusters of flowers that show color without ever really opening until they go to seed as well as deeply lobed leaves. It also is part of the Asteraceae family and both are related. Like the dandelion, if you don’t want it to spread, pull up before it sets seed.
