Description
This selection of Ageratum houstonianum Timeless Mixed, also known as Mexican Paintbrush, produces fairly tall plants that bloom all summer long, with fluffy ball-shaped flowers in three shades of pink, white, and blue, reminiscent of 'cotton candy'. This mix is ideal for adding height to borders or for making long-lasting bouquets. A perennial plant grown as an annual, it thrives in the sun and prefers moist soil.
The Timeless Ageratum mix is a selection of varieties derived from Ageratum houstonianum, a perennial plant grown as an annual from the aster family, native to Central America and the Caribbean. The plants in this selection are relatively tall for the species. They form rounded, dense masses of foliage, reaching 45 cm (18in) in all directions. Very branched and covered in hairs, their numerous stems stand upright while spreading out. The leaves, also hairy, are toothed and oval-shaped. They are sometimes heart-shaped at the base, and their colour is green, more or less dark. From April until early autumn, the flowers bloom continuously if faded flowers are removed regularly. The inflorescences are blue, white, or pink heads, grouped in clusters of pompoms, almost completely hiding the foliage.
Mexican ageratums are often planted in urban landscaping. Their abundant flowers and bright colours allow for interesting combinations with many other low-growing plants in flowerbeds: marigolds, marigold calendulas, or red salvias. It is easy to create a pastel carpet by mixing them with pink begonias and impatiens. The Timeless selection is perfect for making beautiful bouquets. These plants also perform very well in pots, indoors, on the patio, or balcony.
Mexican Paintbrush is a plant that promotes insect pollination. Bees, butterflies, and others.

Planting and care
SOWING: Sow on the surface of a well-drained and moist compost, and cover the seeds with a thin layer of vermiculite. Place the sowing under a greenhouse or keep it in a polyethylene bag at around 20-30°C (68-86°F) until the end of germination, which takes from 7 to 21 days. Expose to light to promote germination.
CULTIVATION: When the young plants are sufficiently developed to be handled, transplant them in clusters into trays or 8cm (3in) pots. Acclimatise them to cooler conditions for a few days before planting them in the ground when all risk of frost has disappeared. Space them 30cm (12in) apart.

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.
