Black-eyed Susan 'Goldsturm' Characteristics
'Goldsturm' are easy to grow perennials that are almost entirely covered by flowers during the summer bloom. While these plants may survive in less that full sun, sun exposure is essential for the best bloom. Some drought and dry soil is tolerable, however this may effect the growth. Good air circulation can help to combat diseases associated with too much moisture. Deadheading spent flowers improves the overall appearance of the plant and encourage additional bloom. Propagation occurs via spreading roots.
Angular leaf spot is a bacterial disease that can threaten the health of 'Goldsturm'. Black spots start small on lower leaves but grow to encompass the whole leaf and moves up the plant. Powdery mildew can also occur.
