Tips On Growing Daylilies Everywhere


For many, the daylily serves as the “perfect perennial,” almost disease-resistant, few pests, tough, almost carefree, adaptable, handles drought well, and just gorgeous colors.

Whether you go east, west, north, or south, you invariably find daylilies in the living garden, for the “daylily” makes one of the most adaptable of plants.

It looks equally at home in perennial beds teamed with:

  • Daffodils
  • Peonies
  • Bearded iris
  • In the shrub border
  • As a background planting
  • In front of evergreens
  • Flanking entrances
  • Edging narrow walks and paths
  • Bordering drives
  • In terraces
  • Rock gardens
  • Beside streams and ponds

… in a single word – ANYWHERE.

Furthermore, they thrive in almost any type of soil.

One reason for both the versatility and popularity of this plant is the vast choice it offers – 1,000’s of varieties in:

  • Yellow
  • Red
  • Orange
  • Lavender
  • Purple
  • Pink
  • Buff
  • Brown
  • Combinations

Its color green height ranges from one to seven feet, and flowers may grow as big as six inches across.

In the North, the daylilies bloom season lasts for many months, and you can plant them as soon as the soil unfreezes. May to November appears as the general bloom time for the South, but some varieties come as early as March.

The peak of the season depends on the temperature; the end of May in the Deep South, middle of July around the Great Lakes.

Sometimes, for convenience sake, daylilies come divided into two groups: deciduous and evergreen. The deciduous types lose their leaves with the coming of winter, in much the same way as perennials, but they come out again in the spring.

As they contain the name evergreens, they look more important in Southern gardens, where you can expect year-round greenness.

Once planted, daylilies grow on their own – so give them a good start. When planting daylilies in beds, work the soil to a depth of 15 inches, putting plenty of humus toward the bottom. Daylilies prefer well-drained soil with lots of organic matter.

Any commercial humus will do, as will peat moss, crushed corn cobs, cottonseed hulls, etc.

For individual plants, prepare a hole 15″ inches deep and 20″ across, filling the bottom with humus. Don’t plant too deep, plant so the crown is an inch below ground level. Spread the roots.

Cut back the daylilies to 4″ or 5″ inches tall for specimen planting, and water thoroughly. In fact, all daylilies like plenty of water from the time flower scapes begin to develop until blooms fade. Dryness will retard bud formation, leading to sickly blooms.

Water from the bottom, sprinkling mars daylily flowers. Daylilies respond to mulching as well as any plant. Everything from peat moss to stable bedding has proved satisfactory.

The idea daylilies bear poor cut flowers makes an incorrect claim, contrary to what some people may believe. Placed in low containers – bowls or trays – they look indeed decorative. Cut flower buds in the afternoon or before the morning when they become due to open.

The full-blooming flower Stella D’Oro daylily will last only a day, but extenders and nocturnals provide blooms for late evening. All in all, the daylily serves as the most dependable and satisfying plant.
