I collect mine and sow in pots of gritty compost rather than trays, more depth and less space taken up.
Come winter there are rows of this and that standing outside the GH
Some people prune these back to stumps every year just at growth starting time. You don't get flowers but great leaves. I'm think of doing that with mine.
I don't see it as a plant that could be trimmed to a rounded shape and kept like that without loosing its impact. Never seen that done though, maybe someone has.
I would lift the fabric and not put it back. It destroys soil structure but also, on a slope, whatever you cover it with will run downhill when it rains and when the birds throw it around,
Geranium macrorrhizum and G. phaeum are good for shade and good at maintaining their form on a slope
That's very likely Bob
persisting here as well
Sow the seed from your new plants when it's ripe. Outside. then you'll have lots more

don't forget some climbers die back, but they're not dead. They regrow from the base. Note the dried curly bits on your 'Boston Ivy'
Boston Ivy doesn't have those.
Some of the photos don't enlarge to a clear image but I think these are all clematis
neither of those photos of Boston Ivy, are Boston Ivy.
My money says they'll germinate
most of the astrantias are fertile Andy. Hadspen Blood certainly is.
When Hadspen Blood germinate prick out the ones with most pigment in the leaves, some aren't very dark, none of the named varieties seed totally true.
I'm having a bit of a poke around re Roma, RHS says deadhead to prevent self seeding
so does Claire Austin https://www.claireaustin-hardyplants.co.uk/products/astrantia-roma
Its sterility might be another one of those things that everyone knows but isn't true.
