This sedum prefers full sun to part shade with a well-drained soil. This perennial is bright enough to attract attention from great distances, which is why it is often used in roadside plantings. An outstanding variety is 'Goldstrum' Rudbeckia. It was chosen as the 1999 Perennial Plant of the Year by the Perennial Plant Association. The height of 'Goldstrum' Rudbeckia, as well as many other Black-eyed Susans, ranges from 2 to 3 feet.
Goldenrod is a wonderful late blooming perennial.
Unfortunately, Goldenrod has gotten a bad rap because it blooms at the same time as ragweed. Ragweed is the source of hayfever problems, not Goldenrod. Goldenrods prefer full sun and a well-drained soil. The foliage has a distinctively sage-like fragrance. Since plants become floppy in shade, full sun is best.
