sooby said:Foliage habit can vary by location and environment, it's not necessarily something that is fixed in a specific cultivar and only reflects the hybridizers observation. So a daylily registered as "dormant" (deciduous) by a hybridizer in a cold winter climate may be evergreen in a warmer one and vice versa and even the other way around, e.g. Stout observed that 'Chengtu' was semi-evergreen or evergreen in New York but "dormant" in Florida.
