Spiraea japonica 'Goldflame' is one of my little favorite shrubs. Plenty hardy zone 4-8 , 3-4' tall and wide for full sun with rose pink flowers. Great fall foliage color on new growth. I give mine a light hair cut after it blooms and then it comes out again with the autumn leaves and flowers so I get two blooming's, it happens so fast I wonder if I could get three blooming's.
It is deciduous , not an evergreen plant.
