I absolutely loved this particular cultivar. I grew it in a collection, and this was the only color that had that heavenly petunia smell - and three plants in a basket filled my porch with fragrance. The seedpods open by themselves, but the seeds tend to stick to the tacky stems and leaves, so bagging would be helpful but not necessary. After the removed seedpods dry the seeds are easily separated.

The group photo was still early in the season - it ended up reaching practically 6 feet to the ground. In milder climates they are supposed to reach 8-10 feet in length.

I got plants last, but I am not sure if they come true to seed - especially since other colors were planted nearby. I germinated some this spring and will report back as soon as they bloom, and when I plant them this year I will keep them separated.
