Lupinus.
The Lupines are distinguished among leguminous plants by their strong, erect, branching habit of growth. Of the numerous species and varieties, some are cultivated for ornament, others for forage, and some for ploughing under for the purpose of enriching the soil. The only species grown for their farinaceous seeds, or which are considered of much value to the gardener, are the two following:—
White Lupine. Law.
Lupinus albus.
An annual species, with a sturdy, erect stem two feet high; leaves oblong, covered with a silvery down, and produced seven or eight together at the end of a common stem; the flowers are white, in loose, terminal spikes; the pods are straight, hairy, about three inches long, and contain five or six large, white, flattened seeds,—these are slightly bitter when eaten, and are reputed to possess important medical properties.
"The White Lupine was extensively cultivated by the Romans for its ripened seeds, which were used for food; and also for its green herbage, which was employed for the support of their domestic animals."
It is of little value as an esculent; and, compared with many other leguminous plants, not worthy of cultivation.
The seeds should be sown where the plants are to remain, as they do not succeed well when transplanted. Sow early in May, in drills sixteen to eighteen inches apart; cover an inch and a half deep, and thin to five or six inches in the rows.
Yellow Lupine. Law.
Lupinus luteus.
