Impatiens

Description

Impatiens are flowering plants that belong to the Balsaminaceae family. They are commonly known as “busy lizzies” or “touch-me-nots” due to their tendency to burst open and scatter their seeds when touched. These plants are native to the tropics and subtropics of Asia and Africa, but they are also widely cultivated in other parts of the world. They come in a variety of colors, including pink, red, purple, white, and orange, making them a popular choice for gardeners who want to add a pop of color to their shady areas.

Taxonomic Information

Appearance

Impatiens are annual plants that can grow up to 60 cm tall. They have succulent stems and oval-shaped leaves that are usually 5-12 cm long. The flowers are asymmetrical and have five petals. The petals are often fused together to form a tubular shape with a spur at the end. The flowers come in a range of colors and can be single or double. They bloom from summer to fall and are popular for their long-lasting flowers.

Care Guide

Impatiens are relatively easy to care for and are a great choice for beginners. Here are some tips to help you care for your impatiens:
