If I was only allowed to take one group of ornamental plants to a desert island I would probably take euphorbia.
An excellent, deep amethyst purple, with a very long flowering season. An invaluable plant for those of us who want to keep our garden full of colour late in the year.
A lovely, bright pink. Brilliant for the autumn garden and the insects love them, laden with pollen and nectar.
A lovely bright lavender-blue flowers around golden hearts – brilliant for the autumn garden and the insects love these, laden with pollen and nectar.
Not an acid-green but a vermilion-orange euphorbia, invaluable as a garden plant and cut flower from early May to mid summer.
A very vigorous shrub with wonderful deep-coloured flowers, the richest of any we've tried.
A classic summer salvia, with deep purple flowers over strong, bushy clumps of deep green leaves and it flowers for ages.
An absolute must in my garden, for a brilliant acid-green backdrop to tulips and alliums.
One of my current favourite border plants and cut flowers. Among the very best foliage plants you can grow looking good for at least six months in the garden. A non-petalled flowering form of Sweet Williams, with vibrant green pompom heads right through summer and autumn.
