Abutilon is related to hibiscus, and its flowers are like pendulous, mini hibiscus flowers with a pronounced staminal column covered in pollen. The habit of the plant is quite open, so it is best to give a good prune when needed to keep the foliage from becoming leggy.
The great thing about abutilons is that they are incredibly hardy, and will cope well where other plants fear to tread, namely, in the damp or dry shade under established trees.
With this in mind, if you plan to plant this, or any flowering or shrubby filler in an established garden, make sure you plant before the soil dries out. It is very hard to establish a plant in these conditions once the soil is dry, unless you are keen to spend a fortune on irrigation and water bills.
I've planted white flowering abutilons as a loose hedge in an established garden along a path within the confines and shade of a very large totara tree - likely to be more than 100 years old. The abutilon "hedge" bushed out and flowered prettily, performing like a trooper. It required very little care apart from the odd mulch and trim to keep it in line, and to ensure repeat flowering. Its little white "lanterns" dangled daintily in the gloom, creating the illusion of lighting the pathway.
