We have one of these plants growing in the front garden - about early June (here in NW England) it displays a massive amount of bright pink flowers, then seems to die off to a very brittle plant - not sure what it is.
Anyway, when it was flowering, we took some cuttings and put them in a pot with a bag over, in the sun, inside the house.
It took really well, and two weeks later, there was loads of little green leaves, and it was getting nice and strong.
I took the bag off the top, and in the following week or two after, they've started to get brittle - though I noticed the parent plant has too, now it's displayed.
Any idea what I should do now?
