General Information:
Rudbeckia Subtomentosa are excellent back-of-the-border plants. Long-lasting blooms from July to frost. Attractive to butterflies and great cut flower. Pairs well with ornamental grasses and tall varieties of New England Asters.
Plant Care:
Do not overfeed or overwater. Prefer moist, fertile well-drained soil. Although drought tolerant, Rudbeckia bloom better with ample moisture. Pinching can produce more compact plants in taller varieties. Allow seeds to fall to assure permanence in the garden. Spent flower heads can be cut back to prevent too many "volunteers". Can be divided every 4 years in spring. Spent foliage can be cut back to 6" for a flush of new growth.
