Shrubs, trees and fruit bushes can all be planted bare-root during the dormant season - and so can many herbaceous perennials. Several mail-order companies supply them bare-root, and they are generally cheaper than plants grown in containers. Planting in the dormant season means that they should establish well, as the roots are directly in contact with the soil.

Discover plants to plant bare-root.
Most bare-root perennials can be planted throughout the dormant season (November to March). When you receive your plants, soak them in a bucket of cold water for a couple of hours, then plant them straight away, or within a few days, as long as the soil is not waterlogged or frozen. Alternatively, pot them up over winter and plant them out in spring.
Here are 10 perennials that establish well from bare-root plants.
Agapanthus
Agapanthus are sun-lovers, with globes of blue or white flowers, and they grow really well in pots. Buying an established plant in a pot can be expensive, so buying bare-root rhizomes is an economical way of growing them. Watch our video on three top tips for growing agapanthus.

Eryngium
Eryngiums, or sea hollies, have spiky, steely blue-grey flowerheads that last well into autumn. They look good in herbaceous borders or gravel gardens and make excellent cut or dried flowers.

Helenium
Cheery, daisy-like heleniums, in 'hot' colours, flower profusely in summer. They combine well with other late flowering perennials such as echinaceas, as well as ornamental grasses.

Heuchera
Heucheras are valued for their large, coloured leaves in a range of colours from dark purple to buttery yellow, and their frothy flowers in summer. They do well in shade and most prefer a moist soil.
