Hi Cyn,
I haven't grown either Dreamland or Magellan, because both are lower growing zinnia varieties and I am concentrating on regular height or higher zinnias. As F1 hybrids, saving seeds from Magellan and/or Dreamland will probably result in considerable variation from the parent varieties, but you should get some that resemble the parents reasonably well. A few might even be better. Crossing Dreamland with Magellan could be interesting. It is possible to "de-hybridize" a hybrid by saving seed only from its "on type" progeny for several generations.
Keep us posted on your activities with Zinnias.
