Winter to Spring in Roses
Winter to spring transition in roses is abundantly clear in my garden this year. A couple of weeks ago we had several days of above average temperatures. Many roses began to send out new growth.
Here in the high desert of New Mexico we are taught not to prune our roses until late March or early April, because pruning stimulates new growth. That tender new growth will die if we get a late freeze, which is not uncommon here in the high desert. So, my roses have not yet been pruned, nor will they be for several weeks. But, because the roses are sending out new growth, I have had the opportunity to photograph old spent blooms and hips with the new growth: a winter to spring transition. I sometimes think of it as “the junction of life and death,” but I realize that is too strong for some readers. I personally find with junction of the remains of last year’s growth and blooms with this year’s brand new growth to be beautiful and interesting.
Some of the new rose leaves are red. This is not a photoshopped color. The red color is due to pigments called anthocyanins, which actually help protect the tender new growth from harsh UV light. As the plants mature, and they no longer need this protection, the pigments disperse, the leaves become green, and become chlorophyll factories through photosynthesis. Not all roses produce the red leaves on early spring growth, however.
