These are all older cultivars that I planted when we first started the garden, so they have been in this very shady bed for 20 years, at least. All bloom well and have overwintered through some extremely harsh conditions. There are a handful that were planted later, maybe in the last 5-10 years or so. This bed doesn't get any direct, full sun and only receives some sun coming in under the tall pine trees. All of the other nearly 200 daylilies that I grow receive some shade throughout the day, some more than others.
