Black-eyed Susan ‘Macau’
Rudbeckia triloba
Description
Of all the black-eyed Susans I’ve ever grown, this is my absolute favorite. By midsummer, this variety can easily reach a towering height of up to 6 ft tall, with individual plants producing up to 25 stems each! The miniature-size flowers are borne in airy sprays, and when added to arrangements, they bring a happy, uplifting quality.
Details
Height: 5 to 6 ft
Site: full sun
Days to maturity: 90 to 100 days
Plant spacing: 9 in
Pinch: not necessary
Seed Sowing & Growing Notes
