Description
Louisa's Song is a spectacular tall bearded iris. Its large, highly ruffled flowers combine a bright mauve-lavender with a deeper purplish violet on the sepals. The tangerine beard highlights the heart of the flower well. This variety has a strong presence in an iris border but remains easy to pair with white, blues, and pinks.
This cultivar ‘Louisa’s Song’ belongs to the group of tall bearded irises, also called large bearded iris. This perennial grows from fleshy, horizontal rhizomes, barely buried. These produce elongated, upright, sword-shaped, glaucous green leaves. Depending on the severity of winter, this foliage may partially or completely disappear. In flower, the plant reaches about 1.07m in height. Its stems branch above the foliage; on a well-established plant, they often carry 3 to 4 branches and up to 8 buds, which extends the flowering period. The variety is early or mid-season; it flowers in May under an average climate. The flowers are large and heavily ruffled, with curled edges that add volume to the corolla. The 3 upright petals are mauve-lavender with an orchid tint. The 3 trailing sepals take on a deeper purplish violet shade, with a lighter edge that highlights their ruffles. The clearly visible, tangerine beard warms the centre of the flower. The scent is light and sweet.
'Louisa’s Song’ was registered in 1999 by Australian breeder Barry Blyth. Its seedling number is E148-1. It comes from the cross ‘Cloud Berry’ × ‘About Town’ and was introduced by Tempo Two in 1999-2000.
Plant Iris ‘Louisa’s Song’ in an iris border or a scree garden. Its rhizomes can be planted in groups of 3 to form a beautiful clump within 3 years. You can pair it with Iris germanica ‘Immortality’, pure white, and Iris germanica ‘Blue Sapphire’ to introduce a crystal silver-blue. A few bulbs of Allium ‘Purple Sensation’ can be planted between the iris clumps. The meadow sage Salvia pratensis ‘Twilight Serenade’, which takes over in summer, can be placed away from the rhizomes.

Planting and care
Plant Iris ‘Louisa's Song’ from July to October. Choose a very sunny spot, with at least six hours of direct sunlight per day, as shade significantly reduces flowering. Plant it in fertile, neutral to alkaline soil, especially well-drained; in clay soil, loosen widely and add gravel or coarse sand to avoid standing water around the rhizome. Position the rhizome almost at the surface, with the upper side visible to the sun, and bury only the roots. Space the young plants 30 to 40cm apart. Water at planting time, then only in case of prolonged drought during the first year. Remove faded flowers, cut the spent flower stalks at the base, and remove dry leaves at the end of winter.
Divide the rhizomes every three or four years, in summer, when the centre of the clump flowers less.

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.
