Monarda didyma ‘Jacob Cline’

5 Photos


Monarda didyma ‘Jacob Cline’ was discovered by Georgia plantsman, Jean Cline, near the Blue Ridge Parkway and named for his son. The cultivar is typically revered as one of the most powdery mildew resistant cultivars available. Oddly, we found ‘Jacob Cline’ to be quite prone to the disease, possible due to the low fertility of our soil. Due to its excellent performance in every category but disease resistance, ‘Jacob Cline’ would have easily been the top bee balm in our trial if its powdery mildew resistance had been as expected. ‘Jacob Cline’ is an incredibly vigorous cultivar, producing an abundant display of large, red flowers. In our trail, it was edged out by ‘Gardenview Scarlet’ as the best red-flowering cultivar based solely on powdery mildew resistance. ‘Jacob Cline’ was by far the most popular bee balm in our trial for attracting hummingbirds.
