Hi katy bug, have you had a chance to look at the negative comments posted on ebay for this seller? If other seeds are not quite right, this one might not be either.

I recently bought Laura Bush seeds from the very reputable Wildseed Farms in Texas, where they sell a choice of Laura Bush magenta, pink or mix (magenta, pink, white), $1.50/packet, but do not sell the Laura Bush white seeds separately.

The advantage of Laura Bush is supposed to be superior heat tolerance and re-seeding in warm climates like mine - my first yr so I will have to see! I guess disadvantage is that there are only the 3 colors above.

No personal knowledge of this company but happened to notice Select Seeds has a fragrant, climbing, heirloom petunia that they claim self-sows. Search for "petunia seed" on the link below or you may have your own fave places to buy. Or what about the wave series? Sorry, I haven't tried that. Good luck!
