If you wish to grow this lily, you must carefully study its native climate, and the habits of the plant when at home.
It is a moderately hardy lily, but will not stand excessive frosts. Neither will it stand great heat. For this reason the bulbs should be planted very deeply. In its native land the bulbs live at the depth of twelve to thirty inches below the surface, and though we do not recommend so great a length as the latter, twelve inches should be the minimum depth at which the bulbs are planted.
A very rich soil is required, but sharp drainage is essential. The latter may be obtained by mixing gravel with the soil.
Whatever you do, the lilies will probably fail, or if they do live, they will give you one or two poor blossoms to repay you for your trouble.
In pots the culture of this lily is rather more satisfactory. The pots must be of good depth and sharp drainage is essential.
The last group of the Eulirions contains three lilies which possess drooping bell-like flowers.
Lilium Parryi is an American species coming from the same place as L. Washingtonianum.
It is a little lily with citron-yellow coloured blossoms and deep orange pollen-grains. The blossoms, of which there are rarely more than three on each stem, are small but pretty and curious.
L. Parryi should be grown in the same way as L. Washingtonianum. It is a difficult plant to flower, but is more satisfactory than its showy ally.
It is rather a rare plant and has not been grown in England for very long.
