Usually May is the month of the Chelsea Flower Show, but this year it's moving to September. However, for this month I must talk about the unofficial star of Chelsea.
A cottage garden favourite, these soaring perennials come in a wide variety of colours and will draw attention wherever you plant them.
They are so simple and easy to grow from seed, it seems a shame not to have a go. Plant established plants in sun or part shade in moist but well drained soil. Prefer a sheltered position and may need staking if exposed.
Vicky’s Top Tip
Keep them well watered during dry periods to stop them getting white fly, which they can be prone to. Protect young plants from hungry slugs and snails.
