Hollyhocks

Alceas rosea or Hollyhocks are typically large perennials, except for certain varieties like Spring Celebrities or Summer Carnival. Annuals, they have the unusual feature of having double flowers of about 5 cm (2in) in diameter with a wide range of colours from July to September. The unbranched floral stems, 75 cm (30in) to 1.50 m (5ft) tall, bear alternate, lobed and rough, light green leaves. Melliferous, these easily cultivated plants like rich, well-drained soils and sunny positions, that are sheltered from the wind which can flatten the flower spikes. Hollyhocks are very susceptible to rust.  Magnificent as a backdrop in borders, they are essential in English gardens. Ideal against a trellis or an old wall.
