Midwest Black Cherry peppers are not fully stable. Any variability will probably in the amount of variegation in the foliage. The peppers have stayed pretty much the same since the F2 generation. The two that I grew this year both had excellent variegation as you can see in the photos. The peppers sometimes start out with some striping that disappears when they turn dark purple. The ripen to red. They grow to about 12 to 18 inches tall in our garden. The Seeds will be F6.
