Gardeners' Notes:

Zemerson's remark about Blue Silk being a parent of Silky Blue is interesting, because upon growing both of these vines from EmmaGrace last summer, I noticed that the seed of both cultivars shares that duality of light and dark seed.

In Silky Blue, the light seeds were slightly darker than the light ones of Blue Silk, and the dark seeds were slightly darker than the dark ones of Blue Silk.

In Silky Blue, out of 3 vines, 11-1 was a blue tending slightly toward turquoise, 11-3 was more of a medium, dusky, powdery blue, and both 11-1 and 11-3 had light seeds. 11-2 started out as a solid dark navy blue flower, but as the season progressed, it had more and more blizzard pattern, and one flower was completely double. 11-2 had the dark seeds.

Both Blue Silk and Silky Blue had large flowers.

It makes you wonder what conditions either inside and/or outside these flowers decide whether to tell the genetic toggle switch, "Umm, I think I'll be dark this time - no! wait a minute - light! Oops - the messenger's already been here."

Beautiful hybrid by EmmaGrace, I believe 'Blue Silk' was one of its parents. The parent seeds I recieved were white like 'Blue Silk's seeds but the seeds I collected were black. The hybrid has black seed genes as well as whitish/cream but they are not as predominant as the cream variation.
