About this variety

Ageratum 'Timeless Mix' Floss Flower 'Timeless Mix'

Tall, straight-stemmed, powder-blue, pink, violet and white fluffy button flowers that never shatter in the vase, add a soft cloud-like texture to any arrangement, and flower continuously from June right through to October from a single spring sowing.

Most of the ageratum sold in garden centres is the squat, dwarf bedding form — useful for window boxes but useless for a cutting garden. 'Timeless Mix' is something different: a properly tall florist's variety bred specifically for cutting, with stems reaching 60–70cm and a habit upright enough to harvest from. The flowers themselves are the reason florists love this plant — soft, fluffy buttons in a mix of cool tones (powder blue, soft pink, violet, white) that hold their shape beautifully in the vase and never shatter. As a half-hardy annual, it earns its place in the cutting patch through sheer volume of stems and an unusually long flowering window.

A note on growing

Sow indoors from February to April at 18–20°C. Surface-sow or cover only very lightly — ageratum benefits from light during germination. Germination takes one to two weeks. Pot on once large enough to handle and grow on in a cool, light position before hardening off. Plant out after all risk of frost has passed in full sun and well-drained soil. Pinch out the growing tip of young plants when they reach 15cm to encourage branching and more cutting stems. Deadhead regularly to keep the flowering going.

Where it shines

In the cutting garden, where its long stems and cloud-like texture make it the indispensable filler for any mixed bouquet — particularly arrangements that lean cool and romantic. The cool blue tones are notoriously hard to find in the cutting flower world, which makes 'Timeless Mix' especially valuable. It also works well in cottage borders as a soft middle-height filler, and the flowers attract bees and small pollinators throughout its long season.

Plant alongside

In the cutting garden, combine with Cornflower, Larkspur, Cosmos and Ammi majus for cool romantic bouquets. In the border, pair with the white clouds of Achillea 'Marshmallow' and the deeper colours of Achillea 'Cerise Queen'.
