The beauty of nature
From an upstairs window i can see my neighbours gardens either side of me. We've all got Clematis montana rubens in our gardens. Judging by the size of the plants, they are different ages and no doubt sourced from different locations.
I beautiful thing to me is that all 3 are opening flower buds this year at the same time. I don't know if this happens every year, i've not noticed.
I guess if i could trace the parentage of our plants back i would find a common relative, just amazes me how that genetic infomation has been preserved and now they know when to open at the same time. Beautiful

Isn't Nature wonderful
Have you been watching the series on bbc4 called Botany, it is really good and exlains every thing about plant life.
Likewise the prog that followed it about the soil consruction, just shows how delicate the balance is.
Yes - I thought they were quite good last night. Good to have real experts presenting the programmes rather than 'presenters'.
The three plants, if they're the same variety will either be part of a clone (grown by cuttings etc. from the same parent) or an inbred variety, selected for its consistency, so in the same conditions, you'd expect them to flower together. It also allows cross pollination between plants (if they're not a clone) so it's advantageous for them too.
Hi Lyn, no I haven't seen that, but it sounds right up my street, I'll have a look on iplayer for it.
hi Steve, yes they probably are the same variety 'Rubens' But clearly different ages judging from the size of the stems. Its just amazing to think they have the same genetic information. I know this can lead to problems, I remember a few years ago a particular bamboo which was propagated by division, flowered and died, hence all the bamboos propagated from that clump died
Sorry BB, i got muddled up, the prog is called Deep down and dirty,
Edited to add, made a mistake (again) right first time, its called Botany:.A Blooming history.
Hi Mike, I'm a Darwinist, I find it odd how a 'creator' would creat such a beautiful planet and put fossils in rocks underground, must have a fun sense of humour i guess! But probably best avoid that subject!
The subject of photoperiodism and tropism is so interesting to me and important to life on this planet.
