Dutch Iris Mammoth Mix (assorted Iris x hollindica) is a randomized mix of elegant blooms with an unmatched presence in any garden! Bright and airy, the Dutch Iris resembles that of an orchid or fleur de lis. Exquisite silky petals come in a range of colors and color combinations. Each bulb produces a single flower that rests atop sturdy stems and is framed by striking clumps of sword-like leaves.
This Mammoth Iris mixture consists of a random selection of Dutch Iris varieties, colors, and solid/bi-colors to produce a unique blend. Purchase several packs of bulbs to enjoy a multitude of blues, purples, white, yellows, and more!
The Mammoth Dutch Iris have larger bulbs and larger flower heads than usual Dutch Iris. Growing outdoors year-round as perennial bulbs in USDA plant hardiness zones 6 to 8, these Irus bulbs can grow 18-24 inches tall when in bloom! Growers in all planting zones can enjoy these as indoor forced accents or as fast-growing annuals in their seasonal containers.
Planting and Application:
This Mammoth Mix and its range of colorful varieties will light up the middle of your garden beds and borders! Mix with other Dutch Iris or mid to late-spring ephemeral bulbs for a grand display that embodies spring! Try mixing Mammoth Iris with Daffodils and Tulips and with Hyacinths, Crocus, and other spring bulbs in a mixed bulb garden!
These ephemerals appreciate having protection from the summer sun, so plant them among larger perennials and shrubs that leaf out later in the spring. These bulb plants shine when in bloom, but then happily bask in the shade of their garden neighbors' foliage for the rest of the growing season.
Either indoors or out, pot up your Mammoth Dutch Iris mix for refreshing color and fragrance. Use on porches and in patio containers, balcony window boxes, or mixed pots on your front stoop, bring curb appeal and smiles everywhere they go! Snip a few for elegant floral arrangements indoors too! But leave a few for the early-emerging pollinators to enjoy outdoors.

#ProPlantTips for Care:
Plant Dutch Iris in sunny, well-drained soil that won't get soggy, but remains consistently moist. Use a 3-4 inch layer of arborist mulch chips to help retain moisture and protect their bulbs (unlike other Irises that grow from rhizomes).
Every few years, it is recommended you divide the bulb clumps and clean out any older, non-productive roots to maintain vigor. Mammoth Dutch Iris should be planted in fall outdoors, or forced indoors in pots during the winter or early spring. Deadhead the flowers after they fade, but keep the leaves to make food for the bulb. Prune away the foliage after it yellows to the ground.
