A cutting is a stem of one plant that you transplant elsewhere to make a new plant. Many plants, including trees in my garden are cutting grown. One side of my garden would be bare if not for cuttings.
Cuttings do take time to root and need care. I keep them damp until they root then pot them up as they grow. They can be planted in the ground once the roots are strong.
Abutilons come in a variety of colours. I find the hybrids with the larger flowers more difficult to strike than the old fashion tall stemmed varieties.
If you have no access to a cutting, buy one and know that the one plant can turn into hundreds in time. It will also bloom generously for months. That is good value.
I am a volunteer propagator for the Huge Plant Sale that raises money for cancer research. Abutilons will be available in our next sale in April so come and buy one from us:
