The 'Stellata' Iris is an old, not very tall variety of Garden Iris, now being brought back into the spotlight for its vigour and the vibrancy and brightness of its small yellow and violet flowers, so different from the enormous frilly corollas of modern varieties. 'Stellata' possesses all the charm of the old diploid iris that brings so much charm to old gardens: it is a prolific and undemanding plant with many bicolour flowers in spring.
The 'Stellata' Iris is a rhizomatous perennial plant that has elegantly upright tufts in spring with its foliage disappearing in winter. It belongs to the Iris family and is one of the many cultivars around for centuries, with its controversial origin being discussed around the number of chromosomes of potential ancestors. It is worth noting that Garden Iris have European origins. They are plants that thrive in chalky soil and require plenty of sunlight, with their rhizomes needing to 'bake' in summer in order to flower. A minimum of 6 hours of sunlight per day is generally required.
'Stellata' will reach a height of between 45 and 60 cm (18 and 24in) when in bloom. Each stem bears numerous buds. The tuft will theoretically spread without a limit over time, with the central rhizomes thinning out in favour of the outer rhizomes. The foliage consists of long and wide sword-shaped leaves, a slightly glaucous green colour with parallel veins. The base of the foliage is purple. Thin and sturdy flowering stems appear in April, with small, simple flowers in May (between the 5th and the 20th of May depending on the year) opening from the top to the lower branches. The petals are straw yellow, the sepals are white streaked with violet-purple and have a thin pale yellow border. The beards are wide and a fairly bright yellow.
Uncertain origin - Would be identical to 'Loreley' (Goos & Koenemann, around 1909)
To accompany the irises, plants should be chosen based on similar needs (exposure, soil...), their vegetation (low-growing plants or light foliage), and their decorative complementarity (appearance, flowering date). For example, Gaura will provide little shade to the irises and will keep the non-flowering iris bed attractive throughout the summer. Eschscholzia will be happy with dry soil in summer, just like the iris. Geraniums, sage, and Libertia also go very well with irises. Slopes and terraced edges can be stabilized by dense planting of old diploid varieties that can remain in place and require little care. If the goal is more decorative and access for care is possible, more modern varieties can be chosen, such as intermediates that are less likely to be knocked down by wind and rain than the tall ones.
You can adorn the vegetable garden with a few clumps or borders of irises grown for cut flowers.

Botanical data
Do you have a sunny, wind-sheltered, warm location, dry in summer?
This is the ideal location for planting Stellata irises! In the shade, they grow but do not flower. They are hardy and do not need winter protection. Well-drained soil is perfect, even dry. German irises require limestone soil: add lime if your soil is acidic. Soil that is too wet promotes rhizome rot. Plant from July to September. This allows the rhizomes enough time to grow sufficiently, and to establish new roots before winter. They should be planted as soon as they are purchased for best results. Plan to divide the irises every 4 years or so to give them fresh soil. They have vigorous growth and require space to develop and flower well. Plant with spacing appropriate to the size and vigour of the variety: about 34-50 cm (13-20in) for large ones. In a monochrome planting, plant the rhizomes in a staggered pattern. To create a mix of colours, plant them in groups of several plants of the same variety. Always consider the direction of rhizome growth by arranging them in a star shape, with buds and leaves facing outward, and spacing them well from other varieties so they have room to develop.
Planting
Dig a hole that is wide and deep enough. Make a wide conical mound of soil in the hole, on which the rhizome and spread-out roots are placed. Cover the roots. It is important that the rhizome is left exposed at the soil surface. It should not be planted in a hollow (risk of rot), so remember that the soil will settle and the iris will sink. In clay or wet soil, the rhizome may even be left elevated on a slight mound of a few centimetres. Lightly compact the soil and thoroughly water it after planting. Water if necessary 2-3 times until establishment.
Maintenance:
Keep the soil free of weeds by shallow hoeing, taking care not to damage the rhizomes or roots. Weeds shade the irises, retain moisture (causing rot), and attract slugs. Likewise, remove dry leaves. If they are diseased (reddish-brown bordered spots of heterosporosis), burn them. Remove faded flowers.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
