Day Lillies flower best in full sun but will tolerate partial shade. Ideal growing conditions are well drained fertile soil but Hemerocallis will tolerate heavier soils and once establish have some resistance to drought.
The reason I tagged Day Lillies as an amber wheelbarrow plant is although easy to grow, they require some maintenance.
The taller, larger Day Lilies will need to be staked. The new growth may look very upright as it emerges, but don't be fooled, the taller varieties of Day Lily look much better with some staking and support. In spring, (or when you get round to it,) as the growth emerges, place a support under their foliage to keep the plant upright and stop it collapsing later in the season when there are many blooms.
In terms of maintenance, Day Lilies need to be dead headed regularly to keep the plant looking good. Each stem has multiple flowers, which is good in the sense of making the plant attractive, but it means dead heading as the flowers are short-lived they need to be removed regularly to keep the plant flowering. After flowering, each stem can be cut to the ground. Once the plant has flowered and the foliage looks tatty, cut the foliage to the ground and it will reward you with fresh lush growth for the rest of the summer, although it will not flower again.
The plus side is that day lilies flower constantly from late spring to early- mid summer, with strong lush foliage and make excellent border plants. They form large clumps, see third image above, and produce good strong colour. They look spectacular, producing large trumpet-shaped flowers in varying shades of yellow, orange, red and deepening down to crimson.
Day Lilies make an excellent cut flower.
