Bulk: Dreamland Hybrid Mix Zinnia Seeds

I have grown these before. We, my wife and I, really like them. I do not have ideal germanition conditions, but reasonably good. In 4 days 10% sprouted, after about 12 days 20% had sprouted, after about 3 weeks a little over half sprouted. Unlikely more will sprout now, so a little disappointed in the germination percentage. In the future I will follow the recommendations of planting 2 seeds per pot and removing the weaker plant. One question is do the faster sprouting seeds tend to be the more robust (vigorous) plants?
I would like the seed packets to carry more information on the variety; like germination time, height and spacing recommended, bloom season, depth to plant the seeds, and best temperature and light or dark requirements for germination. The packaging is unique to the variety with the name anyway.
Sincerely,
Ken

This is my favorite hybrid for drought tolerant zinnias suitable for growing in pot and Seeds N Such have best price. BUT...shipping. UPS Mail Innovations for a pack of seeds? It took a week and a half to get them. A simple stamp on an envelope would do fine.
