Father Feuillee figures and describes three species of Alstroemeria, viz. Pelegrina, Ligtu, and Salsilla, common names by which they are severally distinguished in Peru: the present species, which is much valued by the natives on account of its beauty, he informs us is found wild on a mountain to the north of, and a mile distant from Lima.
From Peru, as might be expected, the present plant found its way into Spain, from whence by the means of his beloved friend Alstroemer, Linnaeus first received seeds of it; the value he set on the acquisition is evident from the great care he took of the seedling plants, preserving them through the winter in his bed-chamber.
According to Mr. Aiton, this species was introduced to the Royal Garden at Kew, by Messrs. Kennedy and Lee, as long ago as the year 1753.
Being a mountainous plant, it is found to be much more hardy than the Ligtu already figured, and is generally treated as a green-house plant; it is found, however, to flower and ripen its seeds better under the glass of a hot-bed frame, where air is freely admitted.
It flowers from June to October, and, though a perennial, is generally raised from seeds, yet may sometimes be increased by parting its roots, which somewhat resemble those of the asparagus: the seeds should be sown in the spring, in a pot of light earth, on a gentle hot-bed, either of dung or tan.
