This very rare plant is a yellow cultivar of the American Copper Iris/Tawny Iris, and has the slender, arching foliage typical of this species. It produces a profusion of butter-yellow blooms with an almost orchid-like appearance on tall stems in May to June. It is a good alternative to our native yellow water iris for smaller ponds.
The American Copper Iris or Tawny Iris (Iris fulva) is easy to grow, not fussy about soil, and not too tall, but has a less compact growth habit than the other Iris species, with more widely-spaced shoots and spreading on rhizomes which are thinner and faster-growing. Because of this, it should ideally be potted on once a year, as it can rapidly reach the edge of its pot. It has much more slender foliage than the other irises, which arches over at the top, and many flowers on each stem. The overall look is more delicate and exotic than any of the other species.
If designing a planting scheme, we recommend approximately 2 Iris fulva 'Marvell Gold' plants per square foot of ground or 1 plant per linear foot of pond edge. Read more on how to pot and care for your plant.
