Coral bells +...?

[WhitedFamily]

Thin garden bed plan along the side of the house. Gets about 50/50 sun and shade. Wanna mostly line with Coral Bells but I'd like to add a few things intermittently to spice it up. Nothing too tall, as it will block windows.
Any ideas?

For the best results plant your Coral Bells in slightly acidic soil that drains well. If your 50/50 is 50% morning Sun it will be ok. However, 50% evening Sun and is in the hottest part of the day I would reconsider planting them there.

Best soil pH 6.0 to 7.0
Coral bells plants prefer partial shade but can take more sun in cold climates. Give them well-drained, moist, rich soil that's neutral to slightly acidic, with a pH of 6.0 to 7.0. Google
