3. Watch The Bloom During the Summer
Black-eyed Susan propagates through seed and blooms in the summer months from June through to September. The flowers attract a variety of animals and insects that enjoy pollinating and grazing on the flowers. Black-eyed Susan produces small black seeds from the brown achene of the flower.
Planting Black-eyed Susan in your yard requires ½-lb of seed per acre for sufficient coverage. When sewn, the seeds grow readily with minimal care needed for successful flowering. The flowers last for most of the summer season and blend well with other grasses, forbs, and legumes in the garden. New seedlings perpetuate from the old crop, and you can expect the seeds to survive the wintertime.
When in full bloom, Black-eyed Susan provides a pleasant aroma and a spectacular visual when planted in bunches. Harvest the flowers at the end of the summer season before the leaves begin to wilt. The flowers last for a week or more when correctly displayed in water with added salts.
