It flowers usually in the beginning of April; the whole plant sends forth a strong unpleasant smell, compared by most writers to that of a fox, perceptible when you approach it; to this effluvia Parkinson endeavours to reconcile us by saying that it is not unwholesome; it is so disagreeable however, that few choose to have many of these plants, or those in the most frequented parts of their gardens, yet it ought not to be proscribed, for independent of its beauty, there is much in it to admire, and especially its singular Nectaria, which in the form of a white glandular excavation decorate the base of each petal; in these usually stands a drop of clear nectareous juice; the peduncle or flower-stalk which bends downwards when the plant is in flower, becomes upright as the seed ripens.
Of this plant, as of all others which have long been objects of culture, there are many varieties; those most generally cultivated in our gardens are the common orange-flowered single and double, yellow single and double, gold-striped leaved, and silver-striped leaved; the Dutch in their catalogues enumerate thirteen varieties.
Luxuriant plants will sometimes produce a second and even a third whorl or crown of flowers, and the flat-stalked ones which are monsters, have been known to produce seventy-two blossoms, but none of these are found to be constant.
The Crown Imperial, though a native of a much warmer climate than ours, is a hardy bulb, and not very nice in regard to soil, succeeds best in such as is stiffish, enriched with manure, and placed in a sheltered situation.
Is propagated by offsets, which are produced in tolerable abundance.
