Perennial - Pennisetum Rubrum "Fireworks" Looks like something from a Dr Suess book! Pennisetum Rubrum is my favorite grass, I wish it was a perennial around here, I'll have to remember to get some for around he house this year.

In my yard: Cottinus coggygria ‘Royal Purple’ . considered a tree but I grow it as a shrub, whacking it back to the ground each spring to keep the height lower and make it bush out. easily grows tall in a season. glows purple with the sun behind it.
