I love this flower. It is a bright burst of color in a garden or in a flower arrangement. Fall has arrived and your Black-Eyed Susans should be losing their petals and dying back. This flower is biennial which means the first year it will not have a flower. This is the time to harvest seeds.
- When the petals have fallen off you are left with a black cone. Cut the cones off and place them in a container that has a lid.
- Cover with the lid and give the container a 30-second hard shake. This will loosen the seeds from the cone.
- Place a colander over a bowl and pour the cones & seeds into the colander. The seeds will fall through the colander. Save seeds in an envelope and store until next planting season. See the chart below.
Zone 7 – June-July
