Veratrum? -- just a guess, post pictures of older,please.

From the first picture and this one, looks a bit like a member of the Zingiberacea family (ginger lilies). Mine die right off in autumn and I forget all about some but when comes spring those shoots, like in your first picture, appear up from the ground. but you'd have to be at least about zone 10 (sub-tropics) for that to happen, and have planted the rootstocks (rhizomes, whatever) previously.

The one in the photo's center looks like Lamium purpureum (Purple Deadnettle). And just a guess - the one to the left, with the long leaves, may be Bignonia capreolata (Crossvine). That one is usually a high-climbing species, but does start out as single-leaved plants tight to the ground. It also has lobed leaves, as shown, and stays green for most of the winter.

Hi Charlie I think you've probably got a few problems going on - phosphorus deficiency is highly likely and there is a possibility you have a few other more minor deficiencies as well. If you check out this page about diagnosing nutrient deficiencies you will be able to get some more information to help you diagnose the issues. The deficiency/ies may be due to a lack of nutrients in the soil but excess water and cold soil will also affect the ability of your plants to take up nutrients. My guess from the information that you have given is that a combination of these things is causing your issues. The above website has a page for each nutrient that describes in more detail the symptoms of nutrient deficiencies (and toxicities) as well as methods for treating the imbalances - including if you need to warm the soil, investigate other toxicities or deficiencies (as these can induce other nutrient imbalances) or reduce watering. As an example, this page describes the symptoms of phosphorus deficiency and how to treat phosphorus deficiency. You may also be interested in this blog post about someone purchasing new soil that was phosphorus deficient. Unfortunately, purchased soil can have as many problems as existing soil sometimes! Luckily there is a lot you can do to remediate your soil. I hope that helps but please feel free to ask any questions you may have.
