This plant is one of the few holiday flowers that makes a big impact. The flower is short lived but comes in many different colors and patterns.
Botanical Name: Hippeastrum sp.
Varieties: HUNDREDS! In my time working at the garden center, purchasing a certain variety wasn't really discussed. We mostly just chose the colors we wanted. They come in shades of white, red, pink, and peach with different patterns. Bright red, and a combination of white and red, is most commonly found.
When you are in the process of trying to get Amaryllis to bloom, you keep it in a very bright window. After it begins blooming, you can prolong the blooms by moving it out of direct sunlight.

Medium moisture is necessary before the plant blooms because it is storing energy and nutrients to push out the flower. After it blooms, watering can be decreased and it can be kept dry.

As I always say, there are LOTS of ways to fertilize plants. Unless you are extremely over-fertilizing your plant, there isn't necessarily a wrong way to do this. I currently use Fox Farm's Grow Big Liquid Fertilizer. I currently don't own an Amaryllis but here is what is suggested from a couple sources...
The Complete Houseplant Survival Manual: "Feed with a balanced all-purpose plant food every 10 days."
University of Minnesota Extension: "Fertilizer amaryllis each time you water at half the recommended strength when new growth is visible. To promote blooming, use a houseplant fertilizer with high phosphorus content. (After flowering) continue to water and fertilize the plant regularly with an all-purpose houseplant plant fertilizer."
It seems like fertilizing normally is the M.O. for these Amaryllis. In the end, how you fertilize is completely up to you! There are tons of products out there you can try, but an overall rule of thumb for houseplants is that it is best to under-fertilize, rather than over-fertilize. Always use the recommended amount, or less, when applying your fertilizer to houseplants.
