Iris purpureobractea seedling with red leaf margins

Here's a better close up of that seedling with the red-margin trait (posted earlier in March).

Below is its papa who carries the red-margin trait (sorry about the messy picture), practically obscured by purple pigmented foliage bases. This one is 1/4 Iris suaveolens var. rubromarginata, which is the original source of the red-margin trait.
