Plants for coastal gardens themed pink and white

Plenty of plants thrive in coastal areas, so it's possible to create a full and attractive border even in these sometimes challenging conditions

Quick facts

  • Plants in coastal areas need to be able to cope with salt ladened winds
  • Coastal plants often have adaptations such as waxy leaves or hairy foliage
  • Choosing the right plants will ensure they are healthy and at their best

The planting plan

James Lawrence, RHS Principal Horticultural Advisor, has designed this simple, attractive, and most importantly, sustainable, border design for you to try at home with plants that are easy to grow, widely available and look good together.
This planting design provides a range of plants with white and pink flowers, that once established will thrive in an environment exposed to drying, salty winds and provide a variety of interest throughout the year. 

Plants for coastal areas

Choosing plants for coastal areas

The main function of this scheme is to provide plants that will thrive in coastal locations which may include salt spray carried inland on strong winds.
Plants such as Olearia, Escallonia and Veronica have thick waxy foliage to help protect the leaves and reduce stress caused by the weather exposure. The Veronica rakaiensis has small leaves whose reduced surface area makes it less likely to be stripped of moisture in windy conditions.  The Hylotelephium has fleshy leaves helping store moisture to be used if drier conditions persist.
The groundcover Sedum helps protect and cover bare soil therefore reducing erosion and the wind’s drying effect on exposed soil. They will also help prevent unwanted plants from self-seeding by reducing areas of bare earth.
Additional organic mulching can further help with soil moisture retention and weed suppression.
1 - Olearia macrodonta 
2 - Escallonia gracilis alba
3 - Veronica ‘Oratia Beauty’ 
4 - Verbena bonariensis
5 - Hylotelephium spectabile ‘Brilliant’
6 - Sedum spectabile (Brilliant Group) ‘Abendrot’ 
7 - Veronica rakaiensis
8 - Escallonia ‘Crimson Spire’

1 - Olearia macrodonta is an evergreen shrub with spiny-toothed, grey-green leaves, white-felted beneath. In summer it has large clusters of small daisy-like, fragrant white flowers.
2 - Escallonia gracilis alba is a medium-sized evergreen shrub with glossy dark green leaves and pure white flowers in mid and late summer.
3 - Veronica ‘Oratia Beauty’ is an evergreen shrub with glossy dark green leaves and pink buds opening to white flowers, giving a pretty bicoloured effect.
4 - Verbena bonariensis is a tall erect perennial with wiry stems bearing oblong leaves and numerous branched clusters of small, bright purple flowers from summer into autumn.  
5 - Hylotelephium spectabile ‘Brilliant’ is an herbaceous perennial, with thick stems bearing shallowly scalloped, waxy grey-green leaves and starry pink flowers in flat heads, in late summer.
6 - Sedum spectabile (Brilliant Group) ‘Abendrot’ is a succulent perennial with heads of small pink and white star-shaped flowers in summer to autumn.
7 - Veronica rakaiensis makes a compact evergreen mound of small, bright green leaves and short spikes of white flowers from early summer.
8 - Escallonia ‘Crimson Spire’ is a medium-sized evergreen shrub with glossy dark green leaves and flowers which are deep crimson, in summer and early autumn.

About Coastal areas

Coastal gardens can often be more exposed to wind which can strip moisture from the plants. Salt spray can also be carried on the wind and this can affect many plants that are not resistant. Coastal locations can also often be warmer and dryer than some inland locations so this can also be a factor in choosing plants.
A simple planting plan helps create depth, interest and good coverage in a border.

The challenge of coastal areas

Coastal locations can sometimes be challenging but by choosing plants that are adapted to the wind, salt and often dry conditions of coastal locations you can keep your border looking good and growing well. However, they will need watering whilst they grow new roots and establish themselves.
If you have room, it will help to make some shelter from the main wind direction. An extra wind break of shrubs will provide this and/or use a brushwood screen whilst they establish. A fence or a sturdy wall may be an option.

Why choose a sustainable planting combination?

Using the ethos of 'right plant, right place' to create a sustainable planting combination is great for the environment. It helps avoid waste and the use of products and practices needed to help ailing plants, such as watering and the application of fertiliser. It also creates a robust, long-lived planting that benefits soil health and garden biodiversity.
