Heuchera ‘Citronelle’

6 Photos


Heuchera ‘Citronelle’ is a large and vigorous cultivar. The fuzzy, electric-yellow leaves emerge in spring with a blinding intensity and slowly fade to bright chartreuse for the rest of the year. This cultivar stood out in our trial for its consistently dense and uniformly mounded habit. ‘Citronelle’, like other chartreuse cultivars, is sensitive to bright sunlight, and extra care should be provided to make sure it receives shade all day long. It is important to note, however, that ‘Citronelle’ displayed the least amount of bleaching when compared to other chartreuse cultivars. The floral display was rated insignificant because the white flowers were not easily seen against the pale foliage.
