Rudbeckia (after the two Professors Rudbeck, father and son).

Compositae. Cone-Flower. Very attractive summer-blooming perennials or

biennials, usually with yellow flowers.

Leaves usually alternate, the blades undivided or in some species much

cut, as in the common Golden Glow: fls. both tubular and ray-like, the

former usually purplish, the latter always yellow; involucre

hemispheric, its bracts imbricated in 2-4 series; receptacle conic or

very rarely convex, with chaffy concave scales subtending the

disk-fls.; disk-fls. perfect, fertile, their corollas 5-lobed: achenes

4-angled, obtuse or truncate at the apex; pappus none or of 2-4 short

teeth.—There are about 31 species, not counting Echi- nacea, all of N.

Amer. Of these scarcely a dozen are of horticultural importance. Under

Rudbeckia are often included in nursery catalogues certain plants here

referred to Echinacea and Lepachys. These three genera form an

interesting floricultural group. Rudbeckia and Lepachys are typically

yellow-fld. genera, while Echinacea is predominately rose-purple-fld.

The chaff of the receptacle is usually persistent in Rudbeckia and

deciduous in Lepachys. Among the hardy herbaceous species, there are

several with striking habit and distinct foliage. There is a wide range

of color in the rays of wild plants and many new races are yet to be

perpetuated. Some of these with variations in the shape, color, length,

color of disk-fls., and so on may serve as the basis of many fine

forms. The season of bloom could doubtless be extended. The only full

double form, apparently, is the Golden Glow, one of the best perennials

of recent intro. Its origin is uncertain, but it appears to be a form

of R. laciniata. About 1894 John Lewis Childs found it among some

plants sent by correspondents. See Gng. 6:370. For structure of the

Rudbeckia inflorescence or head, see Vol. III, Fig. 1535.

The cone-flowers are of easy cultivation in almost any soil and

situation, from a semi-shady position to one in full sun. Most of the

species are found inhabiting moist locations, but thrive well in the

garden under the ordinary methods of cultivation, although R. laciniata

and its double form, Golden Glow, do much better if abundantly supplied

with moisture. R. hirta, the black-eyed Susan,—sometimes called by the

children out West "nigger-heads,"—will thrive in the driest hottest

situation, where many others would fail. The best known as a garden

plant, and probably the showiest, is Golden Glow. If cut back severely

when through blooming and well watered, it often produces a second crop

of flowers. Autumn Glory will be well liked when better known. It is

fine for massing and has a much longer blooming period than Golden

Glow, commencing earlier and continuing until frost. It resembles R.

nitida, an improved form of which, known as Autumn Sun, with bright
primrose-yellow flowers, is a splendid acquisition. It grows 5 to 6
feet high, blooming from August to October. R. triloba is one of the
very best, and, while a biennial, perpetuates itself through self-sown
plants. It forms a dense twiggy bush somewhat over 3 feet high and
nearly as broad if kept moderately well watered, and much smaller if in
a dry situation. These plants may be used with effect as a border to a
large bed of hybrid delphiniums, as the latter will tower above them
and bloom in their young state. By the time the delphiniums are cut
down for their second flowering, the rudbeckias hide their untidiness
and are in their prime. The flowers are somewhat like those of the
ordinary field black-eyed Susan, but smaller, and much more numerous.
While doing best in full sun, they also do remarkably well in semi-shade, as under overhanging shrubs or in shady corners such as the north side of a house would afford. They like a good open soil. When grown in the open with one stake to the center or main stem, and a string run loosely around the whole plant—being,in fact, a string hoop—catching the larger outer branches to prevent breakage by the wind at the connection with the main stem, they make a very handsome compact plant. If well soaked at the roots, they may be taken up when in full bloom, and potted in a 10-inch pot, placed in a dark sheltered place over night, and then used for decorative purposes. They remain in good form for a month in a room or on the porch if not in a draft. They may also be taken up carefully and all the soil washed from the roots, and the roots placed in a large vase filled with water, where they present a bouquet arranged as Nature intended. An effective fall-flowering group may be formed by using the lighter-colored flower forms of Hibiscus syriacus—such as Totus albus, Lady Stanley, and elegantissima—for a center or background, and interspersing groups of the taller rudbeckias (except Golden Glow, which is too tall and spreading) and boltonias next to them. In front of these place R. speciosa and R. triloba, with the blue form of Aconitum Napellus, and for a border use R. bicolor var. superba, placed well to the front to be pulled up when its bloom is past. This group will give color from July until frost. The allied Echinacea purpurea and E. angustifolia are well adapted for grouping in open bays in shrubby borders, as their flowers are extremely durable and seem in harmony with such surroundings. Rudbeckias are easily increased by seeds, cuttings, or division. (W. C. Egan.)
