GIVHANDYS INC Flag Iris

While it arrives in a 4-inch pot, you can transplant it directly into a bog garden or a pond shelf. If placing it in a pond, ensure the crown of the plant is submerged in shallow water, typically no deeper than a few inches.

This iris thrives best in full sunlight. While it may survive in partial shade, you will likely see less vigorous growth and fewer blooms compared to a spot with direct, unfiltered light.

Yellow Flag Iris can be aggressive and is considered invasive in certain regions because it spreads rapidly through rhizomes and seeds. We recommend checking your local environmental guidelines or state invasive species list before planting it in an open water system.

The ideal window for planting is between spring and fall. Getting it established during the warmer months allows the root system to settle in before the plant goes dormant in the winter.

Because this iris spreads, give each plant about 12 to 18 inches of space. This allows the foliage to fill in naturally without overcrowding, which helps maintain good airflow and plant health.
