The common Day Lily is a hardy perennial which can be grown nearly everywhere. It spreads from tuberous roots and once established becomes a permanent resident. They benefit from occasional thinning. My mother-in-law had beds of these in different colors all around her home. If someone admired them she would take her spade and dig up a "start" for them. Varieties number in the thousands.
