Pot Size Guide
Not sure what pot size means? Here's everything you need to know about the sizes we use and which plants they're suited to.
Size by Size
Each size below refers to the pot the plant is currently growing in when dispatched. Larger pots mean more established root systems and bigger plants.
~8cm deep
Best For
Young plugs, alpines & small perennials
Our smallest size — ideal starter plants. Perfect for ground cover, rockeries, or potting on into a larger container at home.
Starter plant~10cm deep
Best For
Herbs, small perennials & compact shrubs
A good all-rounder. Well-rooted and ready to plant straight into the garden or a larger pot. Great value for filling gaps.
Ready to plant~12cm deep
Best For
Perennials, grasses & small ferns
Established plants with a strong root system. Will make an immediate impact in borders. Popular choice for most herbaceous plants.
Established~14cm deep
Best For
Shrubs, large ferns & climbing plants
A solid, well-developed plant. Ideal for feature positions in borders, patio containers, or training up structures. Establishes quickly.
Feature plant~19cm deep
Best For
Larger shrubs, roses & specimen plants
Mature, substantial plants that create instant impact. The root ball is well established — expect visible growth in the first season.
Specimen plant~22cm deep
Best For
Mature shrubs & small ornamental trees
Excellent for statement plantings. A bigger root system means faster establishment and less aftercare required during the first year.
Mature shrub~26cm deep
Best For
Trees, large shrubs & hedging
Large, well-established plants with significant presence. Ideal for focal points, hedgerows, or when you want an immediate mature look.
Large specimen~35cm deep

Planting Tips
- Water before planting — always soak the root ball in water for 20–30 minutes before putting it in the ground.
- Bigger isn't always better — smaller plants often establish faster and can catch up with larger specimens within a season.
- Match pot to planting hole — dig a hole at least twice the width of the pot for best results.
- Aftercare matters most — water regularly for the first year regardless of pot size, especially in dry spells.
