Typical flower of Abutilon shrubs - Abutilon 'Canary Bird'
The Abutilon group are either small trees or shrubs - often evergreen - not always totally hardy. There are several which have Maple-like foliage - sometimes variegated.
All types - even if stated to be hardy - should be grown in a sheltered place - preferably in full sun. Cuttings from all types are easy to root, and as precaution, cuttings should be taken and over wintered in a frost free environment, to ensure continuation for the following year.
Abutilon Canary Bird - Evergreen large shrub or small tree - quick growing and erect in habit. Can reach 10feet in height with not too much of a spread. Yellow flowers - as above - are very attractive and are to be seen from late spring through to fists frosts of Autumn. Often suffers winter scorch and foliage damage in hard winters, but will soo re-grow to fill the original space occupied. Mulch in Autumn to protect roots.
Abutilon Kentish Belle - This evergreen shrub has arching branches which have brown-purple new shoots and pendulous yellow flowers with deep red calyces, which hand down along the new current year's shoots. Can be grown against wall or fence - where it will be hardier.
Abutilon magapotamicum - Unusual in the group as it has a fully pendulous or trailing habit. Foliage is normally evergreen: flowers hang from branches with red calyces and buds from which the yellow flowers emerge - but only a little! Flowers from late Spring through to first Autumn frosts. Does well in a permanent position at foot of sunny wall or fence, with low growing shrubs in front - protecting it through hard winters.
Abutilon x suntense - is a splendid small tree or
large shrub, that will grow to 10 feet quite quickly. Erect habit is
sometimes a bit lax, but it will respond well to pruning as and when
required. The foliage (evergreen) is grey green and downy - not unlike
that of the mallow family, for which it is often mistaken. It has
violet mauve bell flowers that open wide - similar to the Canary Bird -
and is a showy addition to a sun spot in the garden - or happy wandering
over the top of a fence. Quick growing again if damaged in hard winters.
Abitilon x suntense Ralph Gould and A x s, Violetta are my particular favourites, with A x s, Ralph Gould having the slightly larger and open flowers.
Abutilon vitifolium - similar in all respects to Abutilon x suntense - but having white (Abutilon vitifolium var. Album) or pinky mauve (Abutilon vitifolium Veronica Tennant) flowers. The latter has the larges flowers and is a mass of colour throughout late Spring through to Autumn.
Two are worthy of note - and are good for growing in large patio tubs that can be allowed an extra bit of winter protection....
Abutilon pictum Thompsonii - with large mid-green leaves which are splashed with yellow, and soon growing to 8feet! Orange bell flowers - pendant - complete the picture. Plenty of colour and interest for the summer patio. Can also be grown in sheltered, relatively frost-proof area of the garden.
Abutilon 'Souvenir de Bonn' is often sold in garden centres during spring along with the bedding plants. It is attractive because of its yellow edge variegation on dark green glossy leaves, and profusion of orange bell flowers. Over the course of the year - if planted in the garden - it can reach 8 - 10 feet - but will be hit back quite hard with the Autumn frosts. No matter, it is easy to take cuttings, and will often soot out again from the base.
Some can be grown from seed - but the seed is best obtained from a seed supplier for it is difficult to harvest and store.
Whitefly is sometimes a problem if planted outside - as is red spider mite in dry hot summers. Most problems are associated with those grown indoors or in a greenhouse. The list will then extend to mealy bug and brown scale insects.
Simply prune as and when required. In particular, after the winter damage, when most types can be cut back quite hard. This will encourage strong growth - which will soon regain its original height.
Abutilon magapotamicum is best pruned less severely, and simply to train along fence or wall - selecting the strongest shoots to build a framework of flowering new shoots.
