Cornus ?
« on: June 17, 2018, 04:17:20 PM »
This has been growing in a pile of brushwood in my ponies' field for a few years but had no idea what it was and was waiting to see flowers.   I think it is a dogwood - Cornus and a very unexciting one too.  Plain green leaves and green stems.

Roma,
I learned a party trick for deciding is a plant is a Cornus when on a recent trip to RBGE. Take a leaf, holding it lengthwise, and gently pull it apart, to make a tear across the leaf. Some of the main veins will remain intact, and so it is a Cornus. Other leaves do not do this. You can see in the 3rd photo that the torn leaf is hanging by threads. Good, eh?

Well, it would be good if I could send the photos from this tablet, but the system is telling me my files are too big. Sorry.

Odd problem with the picture size, Carolyn.  Normally pix sent from tablets or smart phones  load right away. Perhaps an idea to try loading them within the text as  "Inline full-size image" option.

And then, gently tear the leaf apart.

Then the leaf hangs by a thread and you know it is a cornus.

Thanks for the technical assistance Maggi, now I can get back to posting more photos.

Thank you Carolyn.  I haven't had time to check.  Trying to make watering a bit simpler for my daughter when I go off on holiday and having workmen in the house replacing doors and windows.  I don't know what I'm doing half the time.  I have far too many plants in pots and it's been too dry to plant things out without having to water all the time.  When we do get rain the wind gets up and everything is dry again.

I am am a little bit surprised that there seems no objection against the identification as a 'Cornus'.
I guess it is a member of Caprifoliaceae - perhaps a Lonicera species.

The leaf tearing test did not work in my garden.

I tried Cornus nuttallii, C. kousa and C. stolonifera.  Clean breaks. No threads.

I think it is Lonicera involucrata.
