Coreopsis tripteris ‘Lightning Flash’

5 Photos


Coreopsis tripteris ‘Lightning Flash’ was disappointing due to its susceptibility to severe leaf spot infections as well as having an almost nonexistent floral display. Even without flowers, the foliage color is quite interesting, and it alone could warrant the use of this cultivar. However, each year the leaf spot was so bad that most of the foliage was marred or destroyed. In retrospect, the lighter foliage may not have been able to withstand the full sun and harsh summer temperatures in our garden, and it would have been interesting to evaluate ‘Lightning Flash’ in a part-shade environment. ‘Lightning Flash’ is a rhizomatous cultivar that spreads about 1’ over three years.
