So, a follow up: I've been calling and stopping at the Lowe's frequently just to see. I called yesterday and asked -- when I finally got someone in the garden department AND explained what Citrus meant ("you know, lemons, oranges, grapefruit" ...), the answer came back "yes, we have lemons, limes, and oranges. Well, it's not all that I was looking for, but definitely worth checking out, so I stopped on the way home from work, AND had to make a special detour to get there, since I now am taking an alternate route home as the road the Lowe's is on is under major construction and is a mess. HOW DISAPPOINTING. For $19.98, they have a three to four inch stick in a four inch pot all in a glossy display carton with citrus photos and a "Grow Your Own" label on the box. I mean hey, $20 for a barely rooted cutting. What a joke! And, about half of the probably several hundred plants on the display rack were already dead or clearly dying. The rest of the Lowes garden center was a mess, too -- looked like nothing had been watered for several days, despite the fact it's been like 85 to 90 degrees with no real rain here.

Lycopodium and several showy wildflowers are protected under our state law, but not because they are threatened or endangered. Rather, many years in the past, they were considered at risk of being overcollected from public land for commercial sale, and a concerned group worked to get some protection in place. On private land one may pick/collect/dig/whatever with written permission of the landowner. I guess I'm fortunate to see it often where I work and in several places I hike. I hadn't thought of it as rare. I do have to smile, though, when students and chaperones on field trips think lycopodium is a bunch of baby pine trees.

I used Silver Lace over part of the pergola that covers a portion of my pool patio. Pergola is about 9' tall, about 40' wide and 16' deep. Planted two vines, one over the arched arbor that leads into the pool area. The other vine went up against the pergola. The Silver lace was to cover about half of the pergola, a few New Dawn rose climbers were to cover the other half. Planted the vines a few years ago, they were about 5' tall when planted. The arched arbor is in the bottom left corner of the following photo. You can barely see the vine I planted against the pergola, but you can see the unweathered support pole I used to train it, it's leaning against the second pergola post from the left. By late summer the vines were flowering and had grown over the top of the arbor and over the top of the Pergola. Here's a photo I took today, the vine has grown about 9' vertical to the top, then the full 16' depth of the pergola: I had this same vine when I lived in Wisconsin, on a lake about a half-hour north of MKE. Here in CT it's done well through several winters. No issues. I've seen Silver Lace listed in some places as invasive, but it's never strayed by root, nor has it crowded out some of the other plants near it in the gardens. I think it's just a rigorous climber. The flowers are white and somewhat delicate looking. I guess that's where the "lace" in the name comes from. The petals, when they fall, are not a nuisance. I don't consider it to be a dirty plant in terms of shedding. It's been winter and wind hardy, and provides a nice dappled shade in the summer.

randal92, I don't know what plant you are thinking of, but jewelweed, Impatiens capensis is not listed/protected either for the state of Illinois or federally. It is a common species, not rare. (Plus since this was in a state park, I doubt that Brian would be digging them up.)
