Terri, love the bleeding hearts, I have white and pink but need to add that deep red 'Valentine'. I had the good fortune of being at US National Arboretum several times, but just once was I there at Azalea time (amazing!), but I was there with sister-in-law's family (young children) in tow, so could not linger as long as I'd like.
So you thought about doing more with Polygonatum, it's a wonderful genus, and all the rage currently, great for foliage and "architecture", adding that vertical effect. One of my very favorite ones is Polygonatum odoratum 'Fireworks', it's a variegated one, but not strong or boldly contrasting variegation, instead it's a study of fine striations of white, chartreuse, and green. Chris, some of these Polygonatums could be good plants for naturalizing in your new reclaimed garden space.
Here's my original purchased plant in July 2013
It's lovely in flower, and keeps the variegation throughout the whole growing season.
With many more stems in the second photo in May 2015
In flower in May 2016
Testament to the tough constitution of this plant, the photo on the left taken on Oct 5, 2016, after suffering a record drought (total 3/4" of rain the entire summer, full water ban with $500 fine if caught watering with a hose), the foliage still looks great. Photo on the right is two weeks later, Oct 18, 2016, making quite a splash with gold autumn color.
One of the more fun aspects of this plant is spring emergence, when fat pink noses poke through the ground. Photo on left is early May 2016, second photo is in 2017, the shorter shoots furthest away are all new noses that weren't there in 2016, these plants can increase fairly rapidly. In the photo on the left, the narrow upright plant in front of the tree trunk is a Chinese form of Polygonatum humile, which is very different than the very dwarf form with more rounded leaflets that's common in cultivation...the small form is from Japan.
Parting shot of Polygonatum odoratum 'Fireworks' from spring 2017, with a couple unnamed Epimedium hybrids (that shall stay unnamed because they're not good enough).
