The use of a layer of parchment paper to separate the Hibiscus seedling from the paper towels has been successful beyond my wildest expectations. Attached is a picture of the hybrid Hibiscus seedlings at five and a half days. Starting with 20 seeds, 8 seedlings had well developed root systems of approximately 2 inches in length and were transferred to dirt in pots. 2 seedlings had separated from their shells and need some more time to grow in the Deno Bag. The last 2 seedlings had not as yet separated from their shells and their long-term viability is still known. Out of 20 seeds, 12 seeds or 60% germinated while 8 seeds failed. Given that these seedlings are descended from 5 unique Hibiscus species, the germination rate is quite good.

Even after five and a half days, there is absolutely no tendency for the roots to stick go the parchment paper. I easily picked up the very healthy seedlings between my fingers and transfer them to their new pots without incident. A small spatula or plastic knife would have worked equally as well. In mid August I will be germinating small Dianthus seeds using the same method.
