I have a small hedge (3x) plants of Bobos. They are young plants. Not sure what to plant at the base as far as companion plants. Daylies, perennial geraniums, etc. What are your favorites?

I also have another hedge of Vanilla Strawberries that we just planted yesterday. I was thinking of planting some grasses, maybe red head fountain grass. What do you all think? Any other suggestions.

Thanks!
