companions for Spigelia marilandica
I'm planning to start a new shady bed up close to my house and am very keen to use Spigelia marilandica. I planned to make it the back of the bed but after realizing that it's more bushy than it is tall, I'm thinking it would work better as the middle. So, what to put behind it? The bed faces NW and isn't deep shade - it gets a couple hours of late afternoon / early evening sun, depending on the season.
Help is greatly appreciated!
