Spiraea plant named ‘Conalex’

Abstract

A new variety of Spiraea japonica is provided which displays a distinctive ornamental appearance. Attractive light-green foliage is formed that commonly includes the substantial presence of bright yellow coloration unlike the ‘Lemondrop’ variety (U.S. Plant Pat. No. 15,016). The bright yellow coloration is particularly pronounced when the plant is grown in full sun. Also, unlike the ‘Lemondrop’ variety, the foliage well resists burning when grown in full sun. A dwarf mounding growth habit is displayed. Attractive medium-pink blossoms are formed on a substantially continuous basis that commonly extends from May to October. Good winter hardiness is exhibited. The plant propagates well through the rooting of cuttings.
