| I owe to the kindness of Professor Oliver a sketch of a species of rudbeckia? |
| Even more useful is to be able to distinguish between, say, a hardy perennial rudbeckia and a half hardy annual rudbeckia. |
| In March, plant sunny beds with seed or transplants of marigolds, zinnias, gomphrena and rudbeckia, and brighten shady spots with impatiens and caladiums. |
| As their blooms begin to fade, attention is drawn to the daisy-like flowers of my rudbeckia, which then becomes the predominant focal point. |
| I have become acquainted with several salvias, which the hummingbirds love, and I continue to admire the endless blooms of rudbeckia and yarrow. |
| He showed me a rudbeckia about three feet high with a cone of dark purple flowers, probably a new species. |
