This dwarf iris reaches around 15cm tall, making it a strong choice for detailed, close-up planting in your garden's sunniest spots. Use it in rockeries, alpine troughs, patio pots, low containers, border edges or planted through grass for a more natural spring effect. It grows well with snowdrops, crocus, dwarf narcissi, muscari and other early bulbs, helping create layered colour before larger spring flowers take over. Planted generously, the blooms form a rich purple display that stands out beautifully against gravel, stone, compost and bare winter soil. Plant in autumn in full sun and well-drained soil or compost. Avoid ground that stays wet in winter, water after planting, and allow the narrow grey-green foliage to die back naturally after flowering. Fully hardy and easy to grow, Iris 'Purple Hill' gives early-season containers and borders a confident hit of colour. Supplied as 25 size 6+ bulbs, ready to plant.
The Iris 'Purple Hill' is perfect for gardeners looking to add early-season vibrancy to rockeries, containers, or border edges during the transition from late winter to early spring. These dwarf bulbs offer a distinct, deep purple aesthetic with intricate white and yellow markings, providing a low-maintenance way to brighten your landscape. While these flowers are highly adaptable to various planting styles, they require well-drained soil to thrive, making them unsuitable for areas that become waterlogged during the colder months.

FAQs
When is the best time to plant Iris 'Purple Hill' bulbs?
These bulbs should be planted in the autumn while the soil is still workable and before the ground freezes.
Can I plant these in pots?
Yes, they are excellent for patio pots, troughs, and other low containers provided the containers have adequate drainage holes.
Do I need to lift the bulbs after they flower?
No, Iris 'Purple Hill' is fully hardy and can be left in the ground or in containers year-round.
How much sun do these irises need?
They thrive in full sun locations to encourage strong flowering and healthy foliage growth.
Will they spread over time?
Yes, over several seasons, the bulbs may produce offsets, allowing them to form larger, denser clumps.
What should I do with the foliage after flowering?
Leave it to die back naturally. Do not cut it down prematurely, as the leaves are needed to feed the bulb for next year's growth.
Troubleshooting
Bulbs failing to emerge in spring
This is often caused by winter waterlogging which leads to bulb rot. Ensure your planting site has excellent drainage.
Flowers are weak or stunted
The bulbs may have been planted in a shaded area. Move them to a spot that receives full sun for optimal performance.
Foliage is dying back too early
Check for pests like slugs or environmental stress; ensure the soil does not dry out completely during the active growing phase.
Pros and Cons

Adds intense, deep purple color to the garden when little else is blooming
Highly versatile for small containers, rockeries, and garden beds
Easy to grow and requires minimal long-term maintenance

Setup, Compatibility & Care
Planting: Dig a hole or trench in autumn in a location that receives full sun.
Soil: Ensure the site is well-drained. If your soil is heavy clay, mix in horticultural grit to improve drainage.
Placement: Space bulbs a few centimeters apart. Bury at a depth roughly double the size of the bulb.
Watering: Provide a thorough initial watering after planting to settle the soil. Subsequent watering is rarely needed unless the winter is exceptionally dry.
Post-Bloom Care: Once the flowers fade, leave the narrow grey-green foliage in place. This allows the plant to store energy for the next year. Only remove the leaves once they have turned yellow and withered naturally.
