All Louisiana irises are fast-growing and need regular division, repotting, and plenty of fertilizer. Flowers are large and spectacular. They do best in a warm location and aren’t best suited to frigid areas. They are pretty much evergreen in mild winters, though overwintered leaves may die off just as they flower, spoiling the effect, so trim back in early Spring.They grow to 24" in maturity. After foliage has died back in Autumn cut back to just above the water surface. If trimming left until spring take care not to damage emerging shoots. As with all iris, the tubers are harmful if eaten Flowers: June - July Growth Rate: Medium Depth: 0 - 20 cm Max Height: 80 - 100cm Native to British Isles: n/a Perfect For Pollinators: n/a Position: Full Sun/ Part Shade Planting Marginal Pond Plants Marginal or bog plants are generally sold either as immature plants in smaller pots or maturer plants already in aquatic plant baskets. We recommend any water garden plants in smaller pots are replanted immediately into larger aquatic planting baskets. while pond plants supplied in aquatic baskets can remain in them in they have room to grow, although it is worth bearing in mind that taller plants such as Iris's and grasses will need a deep larger basket as they can be prone to blowing over in the wind, these deeper baskets will provide some counter balance against the wind and plenty of room for root growth. Spreading and rafting pond plants can be planted into shallower baskets, but remember they will need plenty of room for growth, so it is always worth while replanting regularly to ensure the best possible display. If planting a wildlife pond it may be possible to plant directly into a planting area such as a bog area/ garden. Should you wish to contain the growth of these plants in such an area it may still be worth considering sinking the plant in a basket to limit it's spread.
