Iris x hollandica Autumn Princess

A truly distinctive Dutch Iris, Iris hollandica 'Autumn Princess' produces elegant flowers in glowing shades of burnished bronze, warm copper and antique gold, creating an unusually rich and sophisticated display in late spring and early summer.

Unlike the more familiar blue and white Dutch Irises, 'Autumn Princess' stands out with its warm metallic colouring. The beautifully formed flowers feature lustrous bronze and copper standards, complemented by rich orange-brown and plum tones on the falls, each highlighted by a striking golden-yellow signal. As sunlight catches the petals, they seem almost to shimmer with metallic warmth, bringing an entirely different colour palette to the garden.

Held on strong, upright stems above slender sword-like foliage, these elegant blooms make exceptional cut flowers, lasting well in the vase and adding an unusual touch to floral arrangements. They combine beautifully with alliums, geums, ornamental grasses and soft apricot, cream and burgundy perennials.

Easy to grow and wonderfully reliable, 'Autumn Princess' is perfect for sunny borders, gravel gardens and cutting gardens, where its unusual colouring can be fully appreciated.

A superb Dutch Iris for gardeners looking for something a little different from the traditional blues and whites.

Planting Instructions

When to Plant:

Plant Dutch Iris bulbs in autumn, ideally between September and November, while the soil is still warm enough for roots to establish before winter.

Where to Plant:
Choose a sunny position with fertile, well-drained soil. Dutch Irises thrive in borders, gravel gardens and cutting gardens where they receive plenty of sunlight.

How to Plant:

• Depth: Plant bulbs approximately 10–12 cm (4–5 inches) deep.
• Spacing: Space bulbs about 10 cm (4 inches) apart.
• Soil Prep: Improve heavy soils with grit or sharp sand to improve drainage. Incorporate compost or well-rotted organic matter before planting.

Watering:
Water thoroughly after planting to settle the soil. Once established, Dutch Irises need very little additional watering except during prolonged dry spells.

Aftercare Tips:

• Allow the foliage to die back naturally after flowering.
• Feed with a balanced fertiliser after flowering to encourage strong bulbs for the following year.
• Leave bulbs undisturbed where possible to establish larger clumps over time.

Top Tip:
Plant with deep purple alliums, apricot geums or ornamental grasses to complement the warm bronze and copper tones of the flowers.
