Purple Heart Companions
 

If there's one thing I agonize over each year, it's what to plant with
what! Can anyone make a recommendation in what to plant as a
companion to purple heart or Moses in the Cradle? I saw a pic on
plant advisor (url below) of a mass planting with a white-ish looking
plant that was pretty, but I don't have that large an area that gets
proper sun. I got my cuttings started last fall and I'm ready to
enjoy them in the garden on a smaller scale.
I had posted awhile back on lantana and was wondering if this plant
might work well at the feet of my lavender lantana?
