Propagation of Bidens Frondosa L. var. Anomala Porter ex Fern.
Bidens frondosa L. var. anomala Porter ex Fern., also known as devil's beggarticks, is a flowering plant with bright yellow flowers. If you're interested in growing it, you can do so through various propagation methods. Here are three common methods:
Method 1: Seeds
The most common way to propagate Bidens frondosa L. var. anomala Porter ex Fern. is through seeds. The plant produces achenes, which are small seeds that can be harvested when they turn brown. Collect the seeds and dry them in a shaded area, ensuring that they are completely dry before storing them. You can sow the seeds directly in the soil or in seed-starting trays indoors. Ensure that the soil is well-draining and keep it moist until the plant establishes.
Method 2: Stem Cuttings
Another way to propagate Bidens frondosa L. var. anomala Porter ex Fern. is through stem cuttings. Take a stem cutting from a mature plant, making sure it has a few leaves. Remove the leaves from the bottom half of the stem and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. In a few weeks, the plant will start producing roots and can be transplanted outside.
Method 3: Division
You can also propagate Bidens frondosa L. var. anomala Porter ex Fern. through division. This method is best done in spring or fall. Dig up the plant and divide the roots into several sections, ensuring that each section has some shoots and roots. Replant each section in a well-draining soil mix, and water it regularly until it establishes.
