Dwarfed and completely dried up rootstocks... I have my doubts even though I know the young plant is hardy...

Description
Iris germanica 'Lark Ascending' is a large garden iris, offering a long and majestic flowering period with flowers of an almost pure white, animated by imposing mandarin beards. Its beautiful flowers, elegantly undulating, bloom in large numbers for almost 3 weeks, well distributed on very tall stems. This sculptural variety should be placed in the sun and protected from bad weather to preserve its flowering.
Iris 'Lark Ascending' is a rhizomatous perennial plant that develops in spring in elegantly upright clumps, with its foliage disappearing in winter. It belongs to the family of irises. It is one of the many cultivars obtained for centuries, whose controversial origin is discussed around the number of chromosomes of potential ancestors. It should be noted that Garden Irises have European origins. They are plants that thrive in limestone soils and require plenty of sunlight, with their rhizomes needing to "bake" in summer sun in order to flower. A minimum of 6 hours of sunlight per day is generally required.
'Lark Ascending' will reach a height of 1m (3ft) 10cm (4in) when in bloom, with 8 to 9 double buds, and a guaranteed long flowering period. The clump will spread indefinitely over time, with the central rhizomes becoming bare in favor of the outer rhizomes. The foliage consists of long and wide sword-shaped leaves, a slightly glaucous green, with parallel veins. In April, flower stems appear, which will give tightly packed flowers in May, opening from the top towards the lower branches. The color of this plant is, as always with Garden Irises, enhanced by the iridescent texture of the upright petals and the trailing sepals. The beautiful and prominent mandarin orange beard adds to the appeal of this almost white, slightly yellow-tinted large flower.
Bred by Ben Hager, 1996.
To accompany the irises, low-growing plants or those with light foliage that complement the flowering and have compatible cultural requirements should be chosen. For example, Gaura will cast little shade on the irises and will keep the bed attractive throughout the summer. Eschscholzia will be content with a dry soil in summer, just like the irises. Geraniums, salvias, and Libertia also accompany irises very well. The vegetable garden can be adorned with a few clumps or borders of irises, as it is also a classic place for family flower cutting.

Planting and care
Do you have a sunny location, sheltered from the wind, warm and rather dry in summer?
This is the ideal location for planting tall irises! In the shade, they grow but do not flower. Hardy, they do not need winter protection. Well-drained soil is perfect, even if it is rather dry. German irises require a limestone soil: amend your soil with lime if it tends to be acidic. Excessively wet soil promotes rhizome rot. Plant from July to September. This allows the rhizomes to grow sufficiently before being lifted, and to form new roots before winter. They should be planted as soon as they are purchased for best results. Plan to divide irises every 4 years or so to give them fresh soil. They have vigorous growth and require space to develop and flower well. They are planted with spacing appropriate to the size and vigor of the variety: about 34-50cm (13-20in) for tall ones (5 to 10 plants per square meter). In a monochrome planting, the rhizomes are planted in a staggered pattern. To create a mix of colors, it is recommended for the overall aesthetic of the iris bed to 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 to give them room to grow.
Planting
Dig a hole that is wide and deep enough. Create a large 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 just above the surface of the soil. It should not be planted under the soil (risk of rot), so anticipate that the soil will settle and the iris will sink. In clay or damp soil, the rhizome can even be left elevated on a slight mound of a few centimeters. To make the soil adhere to the roots, lightly tamp the soil and water thoroughly immediately after planting. Water 2-3 times if necessary until the plant establishes.
Maintenance:
Keep the soil weed-free by shallow hoeing, taking care not to damage the rhizomes or roots. Weeds shade the irises, retain moisture (causing rot), and attract slugs. Similarly, remove dry leaves. If they are diseased (reddish-brown spots of heterosporiosis), 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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
