Paeonies are the aristocrats of the herbaceous perennial world. The flower stalks rise up above the attractive foliage and each one bears several blooms – blooms which make most other gardenblush with shame. Vast bowls of petals up to 7 in. across – single, semi-double, double or -flowered in a wide array of colours. When making your choice, remember that doubles last longer than singles and the species determines the month when the plants can be expected to bloom . Regard Paeonies as a long-term investment and learn the rules before you start planting. Choose an open, sunny spot but try to avoid a situation where early morning sun will shine on the plants. Early autumn is the best time for planting and the soil should be deeply dug and enriched with or mould. Set the crown of the plant no lower than 1 in. below the soil surface. The main thing you then have to remember is to leave the plant alone – it may not flower in the first season and will not be properly established for three years. Avoid transplanting at all costs and do not try to divide clumps to increase your stock. The cultural rules are quite straightforward – mulch in spring, stake the , water when the weather is dry, deadhead faded blooms, with a general fertilizer in late summer and cut down the to ground level in autumn.
