Blum, A.G. (2016) Zinnia haageana Regel 'Persian Carpet' (Asteraceae) Mexican Zinnia. Flowers photographed in ultraviolet, infrared and visible light. http://www.ultraviol...mexican-zinnia/ [Update: 22 August 2016]

Comment:
This Zinnia cultivar growing at Charlotte Rhoades exhibits a nice mix of singles & doubles and colour variations. Interestingly each ray in the UV has the same UV-dark appearance with UV-bright tips. As Bjørn has commented below, we see here some invariance in the UV signature under cultivation for the Persian Carpet line of Z. haageana.

This is highly interesting. All those cultivars basically have the same UV signature. Of course filled vs non-filled flower heads have the ray flowers arranged differently, but each ray floret apparently responds in a similar fashion in UV.

So, one can postulate that the underlying UV signature is invariant under cultivation. At least this holds for the Zinnia.

Yes, this is an interesting UV example, isn't it?

One of the reasons I pursue UV-photographing of garden Cultivars is that with the wide variety of species and types they present, we can often conduct these little experiments on the UV signatures.

Your comment here reminds me that I should be more diligent about adding Comments to my Cultivar flower posts.
