Not any of the above, but it is a weed. It grows here too. Not even sure that it is a member of the Apiaceae family, but the leaves sure indicate that it might be. I would dig it out. I have Queen Anne's lace. The white umbels are 4 inches across and have the tell-tale small dark red-violet flower in the center. It was long ago said to be a drop of blood from poor Queen Anne. that is not Queen Anne's Lace. It's not Sweet Cicely, Poisonous Hemlock, Wild carrot, Wild Parsley, Wild Celery or any others in that family, but it grows all through the woods and in abandoned fields and roadsides and in many gardens (wink). I know what it isn't, but not what it is! (he he he) ~Annie

WELL...last night someone on name that plant forum indicated that it was called Yellowrocket, which led to finding that it is probably a very close relative of Yellowrocket: Wild Radish. Whis is a very close relative to Wild Mustard :-) The only reason it can't be Yellowrocket is because the stems and leaves have tiny hairs, which indicates it is Wild Radish. However. I have seen pics of Wild Radish now on Google Images that don't look like this plant, and some that show Yellowrocket looking dead-on accurate, save for the leaves. Ha. At any rate, I'm pulling them up...tis' not to be... Thanks so much for your help, timbu and fammsimm. Now I am also familiar with two other kinds of weeds, so if I spot them, I'll know right away :-) Joanna

On these little lowland Cystopteris, they basically act like spring ephemeral flowers. Great big pulse of growth in early spring, then they slowly die back through the summer until there are just a few tattered fronds by fall. Like other spring ephemerals, I assume this is more of an adaptation to light availability through the year rather than having anything to do with moisture. Interestingly, most other species in the genus grow on rock and don't seem to show any strong seasonal pattern apart from losing leaves in winter. Patrick Alexader

Whether it's a weed or not is up to you, Jessica. There's nothing much else in that bed and a lot of empty space to fill so, personally, I'd live with the Silene and just do some judicious control. Obviously, if you have a huge plot which you can't monitor closely you may have other ideas.
