Amaryllis Formosissima is one of the most beautiful in cultivation; it is frequently sold as Jacobea Lily, and known according to some botanical authorities as Sprekelia formossisima. It is very hardy and of easy culture. It must be planted in the open border as soon as the ground becomes warm in the Spring, succeeding best in a rich, sandy soil. As soon as cold weather appears, take up the bulb and place in a warm place in a box of saw dust. In planting, one-third of the bulb must be left above the surface of the soil. The flowers are of a very rich crimson color, they are very large and borne on long footstalks.
Amaryllis Belladonna is one of the oldest and most popular of the Amaryllis in cultivation; it is a native of both continents, being found in Brazil and at Cape Good Hope, although the first introduction into English gardens was from Portugal in 1720, Amaryllis D. Unlike the previous variety, it is very impatient of removal, and should be kept growing constantly in a pot, but should receive no water from November until April. In planting this variety, put at least two inches of drainage in the bottom of a seven-inch pot, then fill in about two inches of rich sandy loam, then taking the neck of the bulb in the fingers of the left hand hold it so the top of the bulb will be at least one-half inch higher than the rim of the pot; spread out the long brittle roots carefully and fill in the soil with the other hand, tapping the pot frequently to settle the soil; there should be half an inch of the pot left unfilled at the top for water; not over one-third of the bulb should be covered with soil. Water well, and place the pot in a warm, light situation; in the last of May sink the pot in the flower bed (putting a little ashes under the pot) and keep it well watered; the flowers will appear in August and September. The flowers are produced on a stalk from two to three feet high, each stalk bearing from one to a dozen blooms, the individual flowers being from three to six inches in diameter.
The ground color of the flower is white, the lower portion usually with a greenish tinge, while the upper part is variegated or suffused with a rosy carmine color; they have a peculiar, but agreeable fragrance. After flowering, the leaves will appear. When the frosty season approaches remove to the house, continue the water supply until the old leaves turn yellow, when gradually withdraw until they are withered entirely, after which no water should be given until the following spring.
With this variety I always pursue a similiar routine of treatment as with the Belladonna, although some authorities recommend continuing its growth during Winter, claiming that it will flower during this season thus having two flowering seasons for the one bulb. The flowers are of the richest and most brilliant scarlet, with a distinct white stripe in the centre of each segment; in size and shape they resemble Lily candiclium. They are gorgeous indeed.
Amaryllis Vittata is a handsome variety with white flowers, variegated with exquisite rose.
Amaryllis Longifiora is a clear rose-colored flower. The two latter require similiar treatment to Belladonna. They are both exceedingly handsome.
