senescence in dandelions

Would you be able to say more? The word 'senescent', to me, means it's old - but all dandelion leaves grow old eventually. There are masses of them around yet this is the only red one I've ever noticed.Don't dandelion leaves usually shrivel and go pale and limp and brown? This leaf had lots of miner damage, I wondered if that had anything to do with it.

about half of the 38

about half of the 38 dandelion species I have in pots outside have red leaves to one extent or another at the moment. Might be a result of drought earlier in the year, these red pigments often protect from too much sun and last longer than the chlorophyll (hence autumn colour).

Dandelions

Thanks for your reply. The best bit is to know you have dandelions in pots. The equal best is to know there you have 38 species. Is that a complete collection or are there more still to be added?

I now know it will be worth submitting dandelion pictures to iSpot to find out which ones are which.

Sorry to be thick about this - not sure what you mean by iSpot key for section hamata. (Have looked under the tab at the top of the page which says 'Keys' but can't see it there.)
