Full disclosure: I grew up in the horticulture business. My uncle David owns Sherwood's Forest, your source for big trees and awesome perennials.
It would seem I have a thing for hostas and heuchera (coral bells). About hostas: divide those mothers up! I split mine frequently. Part the leaves (just like you'd part your hair) and split it in half. I like a Henckels bread knife for cutting the rootball. Replant the other half wherever you'd like a new hosta.
I also have a thing for boutique Japanese maples. The top Jap is a standard upright, but the one on the bottom is a pinkish Full Moon (I think that's what it's called, but that's also the name of sushi so maybe I've confused myself.) I have a groovy little Lion's Head Japanese Maple, but it looks weird right now. Needs a pruning to address some winter deadness.
The sweet yellow flower is a Missouri Primrose- aka Ozark primrose (Onagraceae?) Don't confuse the Missouri primrose with the borderline-weed-but-I-love-it-anyway Mexican primrose a few photos down (oeneothera?, growing out of my sidewalk).
I have three colors of Knock Out shrub rose. The light pink types looks great in the spring but the petals bleach out mid-summer to look dirty white. Buy the darker pinks for better color. Cut this beast back almost to the ground. Frequently
The combo to the left is a Maidenhair fern, cranberry impatien and hosta. I dig the cranberry impatiens. Color snob/Pantone junkie husband John describes it as "Rotamine Red." It works for us- red enough to look red, but not so red that it won't go with pink.
Carrying on with the shade garden is a Japanese painted fern, Ostrich fern and begonia. In 10 years of gardening, this is the FIRST time I've ever been successful with a fern. The key: put them near a water source away from dog traffic.
Totally love the Chocolate coral bells with the lime hosta. This pair sits under a tree on the sidewalk. I've seen many dogs pee on these two and they seem just fine.
Fuschia Peony, Miz-zou pansies, Mexican primrose, Knock-out Bleach-out rose, Allium (member of the onion family- I love these bulbs).
