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.
Summer: Uses one shrub - Cornus alba Aurea, one conifer - Taxus baccata Robusta, one grass - Hakonechloa macra and one perennial - the everblack Ophiopogon planiscapus Nigrescens to create a scene of year round interest
