The large-flowering amaryllis cultivars are the most familiar and most available. Each bulb produces two to three stalks, or scapes, and four to six flowers per scape. They grow to an average of 18 to 24 inches in height. Red varieties include Liberty and Red Lion. Ludwig Dazzler and Christmas Gift have predominately white blooms. Other colors include hot pink, orange, salmon and pink with white. United Nations and Clown varieties are both bold red with white stripes.
Double-flowering amaryllis grow comparably in height and bloom to the large-flowering types, however the flowers are doubled on the stalks, one over another.
Double Picotee has a pure white flower with red edges highlighting the petals. Lady Jane is the name for a soft pink flower with white stripes down the center of each petal. Pasadena is similar but red with white stripes. Other options include the solid colors of red or white and many variations of colored petals with white stripes or picotee edging.
Several miniature single and double amaryllis varieties offer a more petite and less formal bloom. Clusters of 3- to 5-inch flowers appear on multiple12-inch scapes. The bulbs are smaller in comparison to the large-flowering varieties. Leaves usually do not appear until after the bulb has bloomed. An example of a miniature amaryllis is a solid red variety known as Scarlet Baby. Lemon lime and hot pink are other color choices.
Cybister amaryllis hybrids are the newest and least known cultivars. They grow 6 inches across on 24-inch tall scapes. Each flower petal is only about 1/4-inch wide creating a slender spider-like effect. Amaryllis Cybister Evergreen is an exotic green variety. Amaryllis Cybister La Paz has dark coral pointed upper petals descending to greenish-white edges.
