Have spent the morning in the garden doing a bit of tidying and getting things cleaned and ready for sowing and while in the garden noticed that the one of the climbing rose's was making good growth, shoots about 3in high

They're a lot tougher than people give them credit for.

ive got one doing that next to the shed at the plot. Why do the leaves grow red then turn green i wonder?

[Trillium]

I believe it's to do with startup sap from the roots making initial leaves red, then prolonged exposure to light that finally turns them green. Just read an article on it but can't remember all the other details.

The red colour is always there in leaves (or yellow in some cases) and then the chlorophyll/green starts up and is a stronger colour so you only see the leaves as green.

Then at Autumn the chlorophyll dies and you can see the other colour again.

I can't remember the proper names but we did it in uni (a long time ago)
