Growing it in a large container, 'Green Arrow' has been a solid plant. Slower to increase than some, but generous with proliferations if you go to the trouble to collect and grow them. It has not reached the 46" scape height indicated in the database. More like 34-36" so it's well above the foliage but well short of the registration indicated. It has never shown any attempt at rebloom. I've raised a couple of seedlings to blooming size using it as both a pod and pollen parent. Not enough to state with a lot of authority on what it can contribute, but on those few the green seen in the blooms has transmitted fairly strongly. And it's that color that really sets this plant off. In Texas with a harsh sun and warm temperatures, it retains the green. Often green fades to yellow early in daylily blooms under my conditions, so any that retain the green tones are notable. A photo from 4 days ago:
