Irises Plant

Irises make excellent garden focal points with their vibrant spring blooms and striking hues blending or contrasting beautifully when thoughtfully paired with other plants. Use visually appealing companion plants to highlight and not hide prized irises while supporting pollinators too. Consider heights, bloom-times, preferred exposure and maintenance needs for successful designing.

Ground Covers to Foreground Irises

Low-growing ground covers make ideal iris partners covering bare spots while not competing for space, sunlight or nutrients. These accentuate the majestic floral stalks rising above delicately spreading front carpets.

Irises Flowers

Creeping Phlox

Mossy phlox forms colorful April-May carpets with dense needle-like foliage and pretty five-petaled flowers in white, pink, purple, red and blue shades contrasting behind later blooming irises wonderfully. They grow 4-6 inches tall multiplying steadily in sun or light shade indifferently.

Sweet Alyssum

The dainty white fragrant Lobularia flowers blooming April-June on trailing 8 inch stems make sweet alyssum excellent iris associates. Give them full sun, average soil and good drainage for lush carpets. Shear back spent blooms to encourage further flowering.

Dianthus

Spicy clove-scented dianthus form fuzzy blue-green spreading cushions under a foot tall, studded with frilly flowers in red, white, pink or lilac. Easily grown in full sun and well-drained soil, these blooming before bearded irises act as pretty living mulch.
