When does daylily 'Purple d'Oro' flower in my zone?

In zone 5 it flowers late June to mid September. As a summer flower it moves about half a week for every zone: earlier where it is warmer.

Worked out from Hopkins' bioclimatic law: spring arrives about four days later for each degree of latitude north, and one zone is roughly two degrees. A warm spring or a cold one moves any garden two weeks either way.

How far apart should daylily 'Purple d'Oro' be planted?

18 in (45 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 20 in (50 cm), so a group knits into one patch.

It grows 20 in (50 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.

How many daylily 'Purple d'Oro' plants do I need?

At 18 in apart, set out in staggered rows:

• 5 to fill 10 square feet (about 1 m²)
• 7 for a single row 10 ft (3 m) long
• 17 to fill a 4 × 8 ft bed on its own

In a mixed border, plant it as a group of three or five, with a second group further along in the other number.

In the bed above, the planner used three in one group.
