Drones wake from the winter slumber, and help scientist
Now, the plants are older and started flowering. This provides opportunity to re-address the leaf color, in regard to the bracts (flower) color. We also score annually for powdery mildew (Erysiphe pulchra) status.
It was great to receive technological support from Dr. Jamie A. Greig in documenting the leaf color expression... from the above. This sure makes for some powerful pictures, worth thousands of words (and hopefully at least one good Peer-Reviewed OpenAccess paper).
