Description
The Agastache 'Summer Sunset' is part of a series of recent hybrids, selected by an American nursery for their dense and compact habit and their increased floribundity. This agastache offers from summer to autumn, provided it doesn't lack water, upright spikes adorned with long orange buds opening into tubular flowers of a more apricot tone, soon tinged with pink, in a palette of shades worthy of a summer sunset. This easy-to-grow perennial in well-drained but not too dry soil undoubtedly adds a lot of personality to country borders.
The 'Summer Sunset' hybrid Agastache is a plant of the lamiaceae family, related to salvias, catmints, and other thymes. This herbaceous perennial, more perennial in a soil that doesn't retain water in winter, forms a broad upright clump, with highly branched stems, 45 cm (18in) tall and 50 cm (20in) wide. It produces triangular leaves, 5 cm (2in) long, with dentate edges, dark green, which are implanted along the entire length of the angular floral stems. When crushed, they give off a scent of anise mixed with mint. The flowering period extends from June-July to October, without interruption, in the form of highly coloured upright inflorescences, in thin and dense spikes. Each small apricot copper to coral pink tubular flower is surrounded by violet-purple bracts and the colour does not fade in the sun. This particularly melliferous and nectariferous flowering attracts a large number of bees and butterflies.
Easy to grow in well-drained soil, tolerating temporary drought, 'Summer Sunset' Agastache is cultivated in sunny borders with a slightly wild appearance, but also in pots on the terrace, in groups of three identical plants or mixed with blue, violet, or red varieties. In hot regions, it should never lack water during flowering. A carefree perennial, it adds height and consistency to borders composed of grasses (stipa, eragrostis, pennisetum), herbaceous salvias, tall daisies, echinaceas, goldenrod, and asters. It also pairs very well with yellow or orange shrubby potentillas, for example, as well as with the perennial Geranium 'Azure Rush'.
The very fragrant flowers and leaves of Agastache are edible and delicious in salads or fish dishes

Planting and care
Agastache 'Summer Sunset' is a plant that particularly fears waterlogged soils in winter. In our heavy soil, we dig a hole 30 cm (12in) in all directions, pour in pure sand, and plant the stump without adding any soil. This plant requires a sunny and sheltered exposure from heavy frosts. During very severe winters, cover the stumps with straw or dead leaves to form a thick mulch. The soil that welcomes it must be fertile, loose, well-drained but rather moist. The plant can withstand periods of temporary drought, which nevertheless harm flowering.

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.
