Just found this thread and enjoyed reading.
I decided to "conquer" the pelargonium a few years back and am getting better at it.
There is a guy on YouTube called Mr. Pelargonium that grows them exclusively in the UK.
His videos are long sometimes but informative.

I LOVE Well Sweep Farm...I've purchased a number of their scented geraniums.
Surprised how will these guys are overwintering under the bench.
Can someone ID this cascading variety?
