Pandora’s Box daylily is a highly ornamental compact perennial. Neat clumps of bright green strap-like leaves appear in mid spring. Its single, lily-like flowers of cream have purple eye and green throat and appear in early summer atop leafless stems. They will rebloom later in the season with care. Daylily flowers are lightly fragrant and attractive to many pollinators.
This plant is easy to grow if provided with full to part sun and fertile to average, well drained soil. Daylily clumps slowly spread over time and need to be divided ever two to three years. After plants bloom, it is wise to shear back their foliage to allow for a fresh flush of growth. Enjoy ‘Pandora’s Box’ in mixed beds and borders, containers and large mass plantings.

Plant in spring, spacing plants 1 to 3 feet apart, depending on the variety. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the pot the plant is in. Carefully remove the plant from its container and place it in the hole so the top of the root ball is level with the soil surface. Carefully fill in around the root ball and firm the soil gently. Water thoroughly.
Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch to retain moisture and control weeds. Avoid excessive fertilizing as this will inhibit flower production. Water plants during the summer if rainfall is less than 1 inch per week. Remove individual spent flowers daily and cut back flower stalks once all flowers have gone by. Divide plants every three to four years as new growth begins in the spring, lifting plants and dividing them into clumps.
Ligularia – The upright spikes of bright yellow flowers of ‘The Rocket’ ligularia add vertical accents to the more horizontal clumps of daylilies and blend particularly well with red, orange, and yellow cultivars.
Helenium – The yellow or coppery daisy flowers of helenium contrast well with trumpet-shape daylilies in a similar range of colors. Full-sun positions please both.
Yarrow – Yarrow has flattened flower heads in a wide range of colors from pastels to strong golds and yellow. The shape contrasts well with daylily flowers, and you can create interesting color combinations.
