Justicia brandegeana is a popular indoor plant in humid environments, with a distinct feature of colorful flower clusters. It thrives best in USDA Hardiness Zones 8 through 11, where it is warm but protected by moisture during the summer. It can survive all year round in these areas, especially in tropical and semi-tropical environments.
Cultivated shrimp plants are not usually produced by pollination but rather stem cuttings or divisions. To germinate shrimp plant seeds, place them in shallow dirt and keep indoors at room temperature with indirect sunlight.
The flowers bloom for at least 10 months out of the year and have spindly stems that can grow to be about 3 feet and 3 inches in height. They bear drooping clusters of white two-lipped flowers surrounded by colored bracts which are usually shades of white, yellow, and red.
The red variety of the shrimp plant will also have white, pink, and green tones. Its leaves usually have an oval shape and are a bright green color. The shrimp plant grows in the form of a bush.
