large, Kool-Aid-grape color blooms. Very easy to grow and produce a good (manageable) amount of seeds but not quite invasive in my zone.

The seed were easy and fast to sprout. First blooms were a little less than 60 days before they were open. I must say the photo on the package was more of a Purple than the blue you seed in my bloom.

This is a stunning bloom, and it is HUGE 6 inches across face of bloom!!! Very nice to grow again. I had gotten my seeds from someone who got them from the co-op, have discussed the photo of mine compared to the others submitted and came up with this: Mine looked like what hers was from whom I received the seeds :) It is possible there are more than one variety of these?

These seeds were soaked and planted very late (mid June).
The variegated foliage has been enjoyable by itself.
What a treat when this first bloom opened August 24th.
