1-3 -I think maybe Ostrich Fern, Matteuccia struthiopteris 4 -Mountain Laurel, Kalmia latifolia. Very nice shrub. 5-8 -Not sure about these, maybe Iberis? Candytuft 9 -Looks a lot like Mugwort, Artemnisia vulgaris, a weed. Might be something else, though, it's a little early to tell. 10 -Garlic Mustard, definitely a weed. Alliaria petiolata. 11 -Looks like some kind of rose bush. 12,13 -A dandelion and something in the mustard family. Wintercress, maybe. Barbarea vulgaris. 14 -Looks like Columbine, Aquilegia. Probably a garden plant although there is a wild one too. 15 -I should know this and I'm drawing a blank. Privet, maybe? 16,17 -Ornamental grass, can't tell you which one. 18 -Dandelion. Taraxacum vulgaris, if you wanted to know. 19, 20 -Winged Euonymus or Burning Bush, Euonymus alata. The color of the fall leaves is where the 'burning' comes from. Brilliant red. WW PS supposedly you can eat garlic mustard. Somebody at the Brooklyn Botanic Garden, I think, had an article on it. When the world goes down the tubes we can all survive on garlic mustard. There's plenty for everybody around here!

imho Alliaria petiolata is a nasty-bit-o-business from the link below: "ECOLOGICAL THREAT Garlic mustard poses a severe threat to native plants and animals in forest communities in much of the eastern and midwestern U.S. Many native widlflowers that complete their life cycles in the springtime (e.g., spring beauty, wild ginger, bloodroot, Dutchman's breeches, hepatica, toothworts, and trilliums) occur in the same habitat as garlic mustard. Once introduced to an area, garlic mustard outcompetes native plants by aggressively monopolizing light, moisture, nutrients, soil and space. Wildlife species that depend on these early plants for their foliage, pollen, nectar, fruits, seeds and roots, are deprived of these essential food sources when garlic mustard replaces them. Humans are also deprived of the vibrant display of beautiful spring wildflowers. Garlic mustard also poses a threat to one of our rare native insects, the West Virginia white butterfly (Pieris virginiensis). Several species of spring wildflowers known as "toothworts" (Dentaria), also in the mustard family, are the primary food source for the caterpillar stage of this butterfly. Invasions of garlic mustard are causing local extirpations of the toothworts, and chemicals in garlic mustard appear to be toxic to the eggs of the butterfly, as evidenced by their failure to hatch when laid on garlic mustard plants.

Some kind of stress I think. A brief note: Recently doing a project to root 30 cuttings of Lamium maculatum 'Beacon Silver'. Most of these rooted in about 7-10 days in water with large growth of adventitious roots from the stem internodes and a few roots from the nodal areas. 4 of the 30 did not root in that time frame. The leaves, usually a light green edge and a silvery center, turned a purple color like these plants. They rooted in about 17-20 days and most roots were from the nodal points. After growing in potting soil for 2 weeks, all the purple color had disappeared from these plants. Not sure what this implies, or how it relates to your question, but it seemed to show an interplay of this coloration with a low auxin condition. George
