I love the dainty little bells on the Lily of the Valley. They are short-lived blooms but do well in shaded areas and spread well to make a pretty ground-cover.
I think the spirea is so pretty in the Spring and I like the way the branches seem to drape.
Here is more of my effort at planting bulbs last Fall. This allium is blooming and more are on their way.
I got the Solomon's Seal from a friend and have several little pockets of it. It's a great plant for the shade and a perennial. It too will spread.
The dainty little teardrop blossoms on it are likeable as well. The blossoms will disappear and the foliage will be a good feathery look all summer - resembles a big fern.
