This year my hippeastrum has bloomed twice. When I first planted this, I thought it is a pink lily. Later I found out that it is not a lily but amaryllis.
After researching more, I found out that what people thought as amaryllis is actually hippeastrum.
The one that I have is hippeastrum reticulatum. The flowers are pink with reticulated colors on the petals. (Reticulate means having the veins or nerves disposed like the threads of a net)
To make sure that your hippeastrum will reflower, you have to let the bulb retains its original size or gain size. If the hippeastrum has been grown for 2 or more years, offset (daughter) bulblets will be produced. If the bulbs are transferred to a larger pot with the bulblets left attached, you might get a large number of flowering bulbs and create quite a show.
One of these days I am planning to repot the plant. By separating the offsets from the main bulb when repotting into individual pots, I could have a few more pots of hippeastrum in my garden. This type of propagation will produce a flowering bulb in three to four years, which will be identical to the parent plant.
