Description

'Colorado Mix' fills a border with flat, lacy flower heads in a warm spread of colours, from deep red and cerise to apricot, cream, yellow and white. Many flowers soften in tone as they age, so a clump shows several shades at once above ferny, aromatic leaves. It is excellent for cutting, fresh or dried, and the open flower heads are a landing pad for bees, hoverflies and butterflies. Achillea millefolium is tough and drought tolerant, thriving in sunny, free-draining spots where thirstier perennials struggle.

Sowing and growing

  • Sow indoors March to May on the surface of moist seed compost at about 20°C
  • Plant out after the last frosts, or sow outdoors in a seedbed May to June
  • Surface sow and press in; the seed needs light, so barely cover
  • Germination takes 7 to 21 days
  • Full sun in any well-drained soil, including poor and dry ground
  • Grows to about 60 cm tall and 30 cm wide
  • Flowers June to September; early sowings often flower in year one, fuller from year two
  • Hardy herbaceous perennial

Frequently Asked Questions

Will yarrow flower in its first year from seed?

'Colorado' types can flower in the first summer from an early indoor sowing, roughly four months after sowing. First-year flowering is lighter, and established plants give a much fuller display from the second year.

Is yarrow perennial?

Yes. Yarrow is a hardy herbaceous perennial that dies back in winter and returns each spring. It spreads gently into a clump, which can be lifted and divided every three or four years.

Is yarrow good for cut flowers?

Yes. Cut stems when most of the tiny flowers in the head have opened and they last well in water. Hung upside down in a dry, airy place, they also dry well and keep their colour.

What is your returns policy?

We always aim to make sure our customers love our products, but if you do need to return an order within 14 days of purchase (not including plants*), or any items are damaged, we’re happy to help. Just email us directly at hello@growtropicals.com, and we’ll take you through the process. 

Please note: we cannot be held liable for any packaging costs should the original packaging be discarded.

*Unfortunately we cannot accept returns of undamaged plants as these are perishable items and are not saleable upon return. If a plant is damaged, we will compensate for this as per our live arrival guarantee.

When will my order arrive and how much is shipping?

When placing your order, you can choose from three dispatch speeds to suit your needs: Economy (prepared and shipped within 4-5 days), Standard (3-5 days), or Express (dispatched the very next day). Please keep in mind that "dispatch" refers to the time it takes our team to prepare and pack your items before handing them over to the courier, not the total delivery time.

Shipping costs are based on your total order value and will be calculated at checkout, with free shipping automatically applied to all orders over £60. For a full breakdown of shipping prices see our Help Centre.

Additionally, to protect the health and quality of our live plants, orders containing plants are exclusively shipped Monday through Thursday. This careful scheduling prevents your plants from being stuck in a dark shipping depot over the weekend, ensuring they arrive at your door vibrant and healthy.
