Strelitzia nicolai also known as Giant Bird of Paradise, the banana leaf plant or banana leaf palm.
Spider mites are a common problem with giant bird of paradise plants grown indoors. To avoid this, it's important to keep the dust off of the leaves by wiping them down with one teaspoon of rubbing alcohol mixed into a cup of water.
Strelitzia nicolai grown indoors need plenty of light and regular generous watering.
Don’t ever let the soil dry out completely.
This plant can be shy to bloom when its grown as a houseplant, but that’s probably a good thing, as the flowers drip nectar.
