A superb long-petaled cross! Thse have excellent red petals that are long and held on taller stems, with a very interstingly colored pouch! Red Lightning is humboldtii (popowii) x sargentianum. We backcrossed this to humboldtii (popowii).
This is an individual listing for the exact plant shown in the last photo. It has some brown tips on the older growth.
