I think of Lonicera sempervirens when you say coral and I find many rooted sections long the ground. The Orange Honeysuckle looks very similar. Definitely worth a look. Anyway some advice from Plants for a Future website:

which seems to agree with Lady Bird Johnson Wildflower Conservation in CO

"Seed - best sown as soon as it is ripe in a cold frame. Stored seed requires 2 months cold stratification[113] and should be sown as soon as possible in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with or without a heel, July/August in a frame. Good percentage[78]. Cuttings of mature wood of the current season's growth, 15 - 20cm with or without a heel, November in a cold frame. Good percentage[78]. Layering in autumn[200]."
