A fairly common ground cover plant found in yards and around man-made structures. Considered to be an aggressive invasive plant. Rarely found in the interior of New Jersey woodlands though. UV absorption in the central area of flower.

Your Vinca minor is very similar in UV to the European specimens I have photographed

A minor nit to pick, though. 'UV signature' refers to the overall appearance of a flower, not whether some parts are dark and others not.

Damon, I'm very pleased to see you making formal posts now. Your contributions are most welcome!

I will make some very format minor edits:
  • name order - Last Comma First_Initial
  • missing link to this Vinca post in top line
  • minor order change in top line - common name after family name
  • rework bare link (That is a great website you found. I'm going to add it to my links list.)
You can re-word the comment as per Bjørn's suggestion.

Looking good !! Carry on !!

Thanks to you both.

Bjørn--It makes sense it is very similar as it is supposed to have come from over in Europe, Netherlands and some other adjacent areas. I knew I would get some stuff goofed up regarding the UV signature but no worries, I have no ego to bruise. Duly noted and appreciate the feedback. Should we try and describe more details? What are some relevant/useful characteristics that I should look for and comment about (aside from dark and reflective)?


Andrea--I will go ahead and make these edits. I thought I had put the link in. I have been busy taking pictures while stuff is blooming so have quite a few to add when I make the time. I am sure you know what that is all about.:(
My watermelons have a gigantic yellow flower that only open early morning so I am getting that guy tomorrow.

Cheers,

Damon
