The stamens are fused into a tube lined at the mouth with anthers. Inside the tube is the branching style with head-like stigmas. The fruit is a rounded or hemispherical schizocarp with up to 20 segments, each containing a few seeds. Some hybrids have smaller flowers with more of a trumpet shade. They seem to bloom the longest of the varieries. Abutilon hybridum is also commonly known as a Chinese Bellflower or a Chinese Lantern. It is mostly grown as a houseplant and taken outdoors in the warm season. It is a sun lover, but also can develop good in partial shade. If the sun rays are enough it will continually bloom in an impressive way. The fact that Abutilon is a houseplant and it is grown in a container means that it is a specimen plant. It suits very good with clematis or salvia, because of its rich colors.
The soil of the plant should be always wet and it needs a drainage. Re-pot every year. Abutilon takes pruning well. Tip prune young plants, to spur new growth and get a fuller shape. If yours starts to become tall and gangly, snipping it back to a leaf joint will encourage it to send out new branches. Abutilon can also be pruned back hard in the spring, if you want to control its size. Propagating: Propagate by cuttings. Snip about a 4" tip of a branch while the branch is still green and somewhat tender. Leave 3 leaves, but cut off excess leaves and any flowers or buds. The usual houseplant pests will affect Abutilon, including: whiteflies, spider mites, scale and mealybugs. Scout for problems while watering. The diseases affecting Abutilon include: root rot, rust, Alternaria and Cercospora leaf spot. If you grow your Abutilon at home , you need a condidarable amount of room in which to grow. If left unrestrained, they may grow to ten feet in height and spread, so it is important to not provide too large of a planter, nor to feed this plant too well. 
When your plant has reached a suitable size you can control the growth somewhat by pinching, pruning and keeping it slightly root bound. Flowering maples should be pruned to the desired shape in early spring or late fall. They can be trained into a hanging plant growth pattern by pinching back each stem tip every time is grows out two or three inches. To create a more vertical tree like structure, allow only one main stem to remain, and remove all side shoots from it until it reaches the desired height. Then pinch the main tip to force lateral bushiness at the top of the plant.
