A good set of plants for a sunny border is shown below. It is sensible to plant one of each plant that we mention unless we state otherwise below.
Buddleja x weyeriana
Lavandula stoechas (plant about 3)
Syringa microphylla 'Superba'
Sedum spectabile (plant about 6)
Euphorbia myrsinites (plant about 3)
Salvia x sylvestris 'Blauhugel' (plant about 4)
When you plant ensure you look at the expected height of the plants you plant so that you can ensure the taller plants are towards the back of your border.
We can do planting schemes for you. We look at the expected amount of growth to ensure the plants are planted the right distance apart. Alternatively you can buy the plants and we can simply plant them for you.
Before we plan a planting scheme for you we ask you questions about what you would like to achieve with your garden.
