Use caution
Pets in the house? Use caution.
Irises deserve caution around cats and dogs — the rhizomes are the most concerning part, but chewing the leaves or flowers can cause drooling, vomiting, and stomach upset. Keep arrangements out of reach, and contact your veterinarian or an animal poison-control service if a pet chews on them.
What It Means
Named for the Greek goddess of the rainbow, the iris stands for hope, wisdom, faith, and valued messages. Purple irises lean toward admiration and dignity, while blue reads as hope and yellow as passion, making the flower a thoughtful choice for encouragement and congratulations.

Season & Sourcing
Cut Dutch irises are strongest in late winter and spring and thin out through summer. Supply and variety narrow sharply outside the peak, so a florist may suggest alternatives for the same cool, upright color.
Vase life, honestly
Irises are sold in tight bud and open over a day or two, so buying them slightly closed gives the longest display. Once fully open, individual blooms fade in a few days, though a stem often carries a second bud behind the first.
Fragrance
Cut irises carry a faint, fresh scent at most — not a factor for scent-sensitive rooms.
Keeping It Alive
- 1Buy or arrange irises in tight bud for the longest show; they open fast once cut.
- 2Recut stems at an angle and place them in cool, clean water right away.
- 3Strip any foliage that would sit below the waterline.
- 4Keep them cool and out of direct sun to slow the blooms from blowing open.
- 5Refresh the water every two days and pinch off spent blooms so buds behind them can open.
What it costs: In season, Dutch irises are one of the better values for saturated blue-purple color. Bearded garden-type irises are rare in the cut trade and command more when available.
Where It Shines
At weddings
A distinctive accent for spring weddings, adding vertical line and a deep blue-purple that is hard to get from other flowers. Better as a supporting note in mixed arrangements than as a mass flower, since individual blooms are short-lived.
In sympathy work
Purple and blue irises bring dignity and a note of hope to sympathy vases and standing pieces, and they mix well with white lilies and greens in traditional service arrangements.
Every day
A lovely seasonal bunch on their own or mixed with tulips and daffodils for a spring gift. Their upright form suits a tall, simple vase.

A Little History
The iris is named for Iris, the Greek goddess who personified the rainbow, reflecting the flower's wide color range. It has been a heraldic emblem for centuries — the stylized fleur-de-lis, long associated with French royalty, is generally understood to derive from the iris.
Questions People Ask
Why do my cut irises open and fade so fast?
Irises are sold in bud and bloom quickly once cut, and each open flower only lasts a few days. Buy them tight, keep them cool, and remove spent blooms so the second bud on the stem can open and extend the display.
When are cut irises in season?
Dutch irises are strongest from late winter through spring and become scarce in summer and fall. Outside the peak, delphinium or lisianthus can supply a similar cool, upright color.
What do purple irises mean?
Purple irises traditionally signal admiration, dignity, and wisdom, while blue leans toward hope and faith. That makes them a thoughtful pick for congratulations, encouragement, or a note of respect.
Are irises a concern around pets?
Yes — use caution with cats and dogs. The rhizome is the most concerning part, but chewing leaves or flowers can cause drooling and stomach upset, so keep them out of reach and call your veterinarian or an animal poison-control service if a pet gets into them.
