Herissantia crispa, also known as Bladdermallow is a small plant native to Tropical Americas. Growing from 2-5 feet, Herissantia crispa is a low-growing woody perennial that features clustered small white or off-white flowers on short stalks. The flowers have five pale yellow oval petals each up to a centimeter long and the fruits are a lantern-like inflated sphere ribbed into segments. The plant has a moderate water requirement and prefers semi-shade to full sun exposure. Best grown in USDA Zone 9-11, Herissantia crispa can also thrive in cooler regions in a pot with proper care.
The ideal conditions for growing Herissantia crispa in pot would be a well-drained pot that is at least 10 inches in depth with full sun exposure and a medium to regular watering schedule. It is important to protect the roots from extreme winter temperatures by placing the pot in a sheltered and sunny area. Furthermore, mulching the pot around the roots will help to retain soil moisture and insulate the plant from temperature fluctuations. If the leaves begin to turn yellow, water may be necessary to prevent any further damage and nourish the plant. Additionally, if frost is expected, it is important to move the pot indoors or to a warmer area. With the right care and attention, Herissantia crispa can thrive and be enjoyed for years to come.
