Long lasting bright yellow flowers appear, crowded on upright stems for months in summer on tall growing plants.
Mentioned in the traditional English folk song 'In an English Country Garden' Hollyhocks have been grown in our gardens for centuries. A classic cottage garden flower that's easy to grow in a sunny border, this lovely plant is often grown next to a wall or fence to add summer height and colour. In the first year, the plant concentrates on growing a big clump of rounded, olive-green leaves and in the second summer, tall stems appear studded with double bright yellow flowers that look like crepe paper. Because the flowers don't set seed, they are long lasting and appear for several weeks. Beautiful in a mixed border and especially when planted to give height amongst old Roses, Hollyhocks are also suitable for gravel gardens where their upright shape and bold leaves will blend well with grasses and leafy perennials.

Hollyhocks are short lived perennial plants which means that they will last for a few years but don't have the longevity of some other plants. They are well worth growing in a sunny, well drained position for their summer show of flowers. Choose a sheltered spot or support the plants with twigs, canes or special structures to keep the flowering stems upright. When planting, dig a hole that's at least twice the size of the existing container and add a suitable general fertiliser to the soil that's to be used to infill around the roots. Water your plant well before and after planting. Each spring a handful of general fertiliser can be sprinkled around the base of the plants, taking care not to cover the leaves and stems. A layer of garden compost or well rotted manure can be added to top up the soil around the plant. Once your plant has finished flowering, cut the stems back to about 30cm and then to the ground in spring once the new leaves are seen.
