|I have sugar tip which is double flowered variegated rose of sharon, rarely produces seed but possible. Then I have a variegated, naturally occurring form of your garden variety rose of Sharon. They have potential to cross pollinate, will the offspring carry variegated trait?|

|The answer is usually no, but it can depend on a lot of things:|
1---What kind of variegation?
-- -- -- -- outer leaf edge
-- -- -- -- interveinal or veinal
-- -- -- -- spotting
-- -- -- -- streaking
-- -- -- -- regular or irregular
2---If the "naturally occurring" variegated plants grow that way from seed, than there is a better chance that the trait will show up in at least some of the offspring. Generally speaking with flowering plants, if the variegation originated from a growth on a non-variegated plant, the trait will not be transferable sexually (by seed).

|I thought heritable variegation of foliage in plants was usually mitochondrial inheritance and only came from the pod parent. The pollen parent would have no effect at all, whether variegated or not.|

|Seems I now remember that, too. He didn't say if he would do the crossing one or both ways, and it's good you thought to mention it.|

|Here is the kind I bought- http://www.monrovia.com/plant-...|
Here is the one that sprouted from seed of a non variegated plant - http://garden.org/pics/2014-08...

|I think if you can get seeds from either one, there is a possibility of getting a variegated plant. It's been a long time since I was looking into how it works and I can't remember how likely it is. If I'm remembering correctly, it doesn't matter who provides the pollen since the variegation is heritable only from the pod parent. A caveat, though. There are types of variegation that are produced by bad matches of chromosomes between the two parents. That type of variegation is not heritable, I believe. But the most common type of variegation should stem from mom, not dad.|
