'Red Lion' amaryllis plants require well-drained soil, filtered sunlight and staking of the flower stalk. Water the plant when the top 1 to 2 inches of soil feels dry. Indirect, bright light from a west or south-facing window meets the needs of this plant and staking provides support to the flower as the stalks have a tendency to bend over,
'Red Lion' amaryllis plants grow flower stalks from a bulb, producing large, red flowers. Hardy in U.S. Department of Agriculture zones 9 through 11, the plant may also be grown indoors. The flower stalk of the 'Red Lion' amaryllis produces four blooms. These blooms open in sequence, two or three days apart. The life of the blooms can be extended by keeping the plant in a cool spot.
The stalk should be clipped 2 inches above the bulb once the flowers are gone. The leaves should not be clipped. Fertilize with a 10-10-10 formula every two to three weeks while the leaves are green. Once the leaves die back, withhold fertilizer and water. This is when the plant enters dormancy. Bring the 'Red Lion' amaryllis indoors before the first frost, keeping it in a cool, dark spot until spring.
