The Tree Mallows are a group of 5 species with a Mediterranean-Atlantic distribution. They appear not to be a natural grouping, forming a clade with the Pacific Lavateras (Californian Lavateras and Australian Hollyhock), Malva sylvestris, and the weedy mallows of cool temperate climates. The first 2 were transferred to Malva in 1998 by M.F. Ray, on the basis of flower and fruit axis characteristics, and DNA sequences, as Malva dendromorpha M.F. Ray and Malva linnaei M.F. Ray [1]. In the absence of DNA evidence he refrained from transferring Lavatera mauritanica. Subsequent DNA sequence data from Escobar et al [2] confirms its position in Malva, where the correct name is Malva durieui Spach.) Lavatera microphylla and Lavatera vidali are obscure Moroccan species which are grouped with the tree mallows, and transferred to Malva, by Molero and Montserrat [3]. The correct names for the first two species are Malva arborea [4] and Malva pseudolavatera Webb & Berth. [3, 5].

Malva arborea is the Tree Mallow, and Malva pseudolavatera the Smaller Tree Mallow. These names are misleading; Malva arborea is a biennial, occasionally perennial, sub-shrub with erect stems to 3m height, woody below, and Malva pseudolavatera an annual or biennial herb growing to 1 or exceptionally 1½m.. Malva pseudolavatera is also known as the Cornish Mallow. Malva durieui is an erect annual.

Malva arborea is of horticultural merit, and is occasionally found in gardens, especially as cultivar 'Variegata'. Malva pseudolavatera and Malva durieui are also grown, but in my experience the flowers are neither sufficiently showy nor abundant for them to warrant a place in a garden. This may be different in hotter climates; I have observed a reluctance for the flowers to open on overcast days.

Detailed description with photo-illustrations.


Malva arborea is found on the coasts of the Mediterranean and Western Europe, and in North Africa. In Britain it is found principally on the south and west coasts (as far north as Ayr) and on the south coast of Ireland, but also occurs on the east coast, e.g. East Lothian. It is naturalised in many locations, including coastal California, Victoria and Swanland in Australia, and the Canary Islands.


The non-woody parts of Malva arborea are downy to hairy (with star-shaped hairs). The velvety leaves are 5-7 lobed. The flowers are 3-5cm across, and are lilac or purplish-pink in colour with purple veins, and darker bases. They are borne in terminal racemes. The epicalyx is a 3-lobed cup of broadly oval segments wider than the calyx, especially in fruit. The nutlets are wrinkled.


Malva arborea 'Variegata' is a variegated cultivar. It is sparsely variegated, or unvariegated, in its 1st season, followed in subsequent seasons by leaves and epicalyxes heavily marbled with white.

Other recorded cultivars are 'Alborosea', 'Isle de Hyères' and 'Molly Miller'.

Lavatera arborea 'Rosea' is an incorrect name for Lavatera ×clementii 'Rosea'

Malva arborea prefers a light well drained moderately fertile soil in full sun, but will succeed in any ordinary garden soil in sun or partial shade. Too fertile soil, or overuse of fertiliser, will encourage vegetative growth at the expense of flowering. Though not strictly a biennial, it is commonly monocarpic, and is best treated as a biennial

It is hardy to zone 8, and must be treated as an annual or a half-hardy biennial in the remainder of North America.

Malva arborea should not be pruned in its 1st season.


Grown from seed, sown in situ in late summer. Generally produces good seed, and will self seed. (In some parts of the world it is a potential weed.)

Detailed description with photo-illustrations.

Malva pseudolavatera is an erect hairy annual or biennial found in the Near East and Mediterranean region, including North Africa and the Canary Islands, and in Western Europe north to Brittany and Cornwall, growing to 2-4 feet in height. It is also found (naturalised?) in Madeira and the Azores, and is naturalised in a number of other regions. It bears small lilac flowers, in clusters in the leaf axils, in early summer.

Detailed description with photo-illustrations.

Malva durieui is an erect hairy annual (with stellate hairs) from south and central Portugal and eastern Spain (ssp. davaei) and north west Africa (ssp. mauritanica) growing to 2-4 feet in height. (To the best of my knowledge the combination Malva durieui ssp. davaei has not been formally published.) It bears small rose-pink flowers, with darker eyes, in pairs in the leaf axils, in early summer.

Malva microphylla (E.G. Baker) Molero & J.M. Monts.

Malva microphylla is a herbaceous plant, growing to 1 ft in height, with serrate, ovate, trilobate leaves, and slightly bilobate purple flowers. It is found in the region of the Sherat River, in the vicinity of Rabat in Morrocco.

Synonyms of Malva microphylla include Althaea microphylla Kuntze and Lavatera microphylla Baker f..

Malva vidali (Pau) Molero & J. M. Monts.

Malva vidali is known from a single collection from Morocco. It is distinguished from Malva pseudolavatera in being consistently annual, and in having long petioles (leaf stalks) [3].

Lavatera vidali Pau is a synonym of Malva vidali.
