The main danger with the cuttings getting frozen is dessication. Swenson Red should be actually hardy to -25 to -30, but freezing unrooted cuttings can draw the water out of the cells. Keep them wrapped in moist (not drippy) paper in a plastic bag someplace where they will stay near 32 (0 C) and they can be held for as much as a year, if not more.

my porch (which is currently below 0 F)?
Lon Rombough needs answer this question as he is the expert. However, below zero can damage buds and I would place in the refrig. Also if it gets too warm the buds can break dormancy reducing the graft success rate.
