Abutilon Megapotamicum
Known affectionately as the Trailing Abutilon or the Brazilian Bell Flower, this plant looks like a collection of hand-crafted Victorian ornaments draped over a delicate shrub. Hailing from the riverbanks of Brazil, its "lanterns" seem to glow against its dark green foliage, making it a favorite for those looking to add a touch of tropical elegance to a patio or conservatory.
The species name megapotamicum literally translates to "from the big river," referring to the Rio Grande in Brazil. Its nectar-rich lanterns are specifically designed to be "hover-fed" by hummingbirds, who act as its primary pollinators in the wild.

To grow Abutilon megapotamicum, also known as the flowering maple or trailing abutilon, you can follow these steps:


To properly fertilize this plant, use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. Apply the fertilizer once every two months during the growing season, which is typically in the spring and summer. Be sure to follow the instructions on the fertilizer package for the correct amount to use based on the size of your plant. To avoid over-fertilization, water the plant before and after the fertilizer application and avoid fertilizing during periods of drought or extreme heat.
Abutilon megapotamicum is a type of flowering plant that requires a specific type of soil to thrive. The ideal soil for this plant should be well-draining and loamy, with a pH level of around 6.0 to 7.0. It should also be rich in nutrients, particularly nitrogen, phosphorus, and potassium, to support healthy growth and blooming. The soil should be moist but not waterlogged, as excess water can lead to root rot and other fungal diseases. To enhance the soil's fertility, gardeners can add organic matter, such as compost or well-rotted manure, to the top layer of soil or use a slow-release fertilizer. It's important to avoid using heavy clay soils or soils that have a high salt content, as these can be detrimental to Abutilon megapotamicum's health. Overall, providing well-draining, fertile soil that is kept consistently moist can help ensure Abutilon megapotamicum thrives in the garden or container.
Abutilon Megapotamicum can be propagated through seeds, cuttings or layering. To propagate Abutilon Megapotamicum through seeds, collect the matured seeds from the mother plant, sow them in a well-draining potting mix, cover with a thin layer of soil, and keep the soil moist until the seeds germinate.
To propagate Abutilon Megapotamicum through cuttings, take a 3-4 inches long stem cutting that has a few healthy leaves, remove the lower leaves, dip the stem in a rooting hormone, and plant it in a well-draining potting mix. Keep the soil moist and in a bright, warm location until the roots develop.
To propagate Abutilon Megapotamicum through layering, take a flexible stem and bend it down to the soil surface. Gently scrape off the top layer of the bark where the stem touches the soil, apply rooting hormone, and cover the stem with soil. Keep the soil moist until roots develop, and then separate the new plant from the mother plant.
