Our achillea plants are supplied as 2cm dia plugs to plant-on in a pot or plant directly in your garden. This beautiful variety 'Colorado' has attractive rusty red, pink and yellow colours, said to be like the colours of the Grand Canyon and Colorado River. You can buy three, five or six plugs with this order. Dig a small hole, put the plug with the roots in the ground and press soil around. Water well. Please contact us for any other gardening advice.
