Pale Yellow Flag Iris (Iris pseudacorus var. bastardii)
Rare pale yellow water iris for natural pond planting and wildlife habitats
Pale Yellow Flag Iris (Iris pseudacorus var. bastardii) is a rare and elegant variation of the native Yellow Flag Iris, valued for its softer, more refined appearance. Unlike the bold golden tones of the standard species, this variety produces delicate pale yellow flowers that bring a subtle and natural look to pond margins and wetland planting schemes.
Flowering from May through to July, this marginal plant creates a beautiful early to mid summer display. The blooms are lightly coloured, giving a softer visual impact while still providing excellent interest and contrast within naturalistic planting. These flowers are also highly attractive to pollinators such as bees, helping to support biodiversity around your pond.
Growing up to 120 cm tall, Pale Yellow Flag Iris (Iris pseudacorus var. bastardii) offers strong vertical structure with its upright, sword like foliage. The dense green leaves remain attractive throughout the season and provide excellent shelter for pond wildlife, including frogs, newts, and insects. This makes it an ideal choice for wildlife ponds, lakes, and conservation style planting.
This plant thrives in moist to wet soil conditions and can be planted in shallow water up to around 20 cm deep. It is best suited to larger ponds, lakes, and naturalised areas where it has space to establish and spread. While slightly less vigorous than the standard Yellow Flag Iris, it still develops through rhizomes and should be given adequate room to grow.
Pale Yellow Flag Iris (Iris pseudacorus var. bastardii) performs best in full sun but will tolerate partial shade. Once established, it is extremely hardy and reliable, making it a low maintenance option for larger water features. For smaller ponds, it is recommended to keep the plant in an aquatic basket to help manage its spread.
This is a fantastic option for anyone looking to achieve a softer, more natural pond edge with all the ecological benefits of a native iris, but with a more understated and elegant colour palette.
Please note that all parts of the plant are harmful if ingested.
