The 'hollyhocks' comprise about 60 species of
flowering plants in the genus '''Alcea''' (''
Ál-ce-a'') in the mallow family
Malvaceae, native to southwest and central
Asia. They are biennial or short-lived perennial plants growing to 3.5 m tall, with broad, rounded, palmately lobed
leaves and numerous
flowers, pink or yellow in the wild species, on the erect central stem.
''Alcea'' species are used as food plants by the
larvae of some
Lepidoptera species including ''
Bucculatrix quadrigemina'' and the
Painted Lady (''Vanessa cardui'').

Uses

A dark purple flowered cultivar of ''A. rosea''
Hollyhocks are popular
garden ornamental plants,
cultivars selected, particularly from ''A. rosea''. The flowers have been selected for variations in colour, with dark purple, red and white-flowered plants available in addition to the colours found in wild plants.
Hollyhocks are very drought resistant, and do well in full sun locations that might be too hot or dry for other plants. They produce large, flat coin-shaped seeds (1/2" diameter) that seem to grow easily wherever they drop. While an individual plant might only live a handful of years, by that time chances are good it will leave plenty of descendants. They have very long taproots which make transplanting difficult.
Culture
A stylized, symmetrical hollyhock is the seal of the
Tokugawa family in
Japan, and is often used as a reference to the era in Japan's history where that family ruled the country.
Also known is the character '
Aoi no Ue' (or 'Awoi no Uye' 葵上, 'Lady Hollyhock') from
The Tale of Genji.
