Onoclea sensibilis

What is the plant

Onoclea Sensibilis is a perennial fern plant from the Onocleaceae family famous for its lush tropical appearance. In the wild, this plant thrives in the Far East, North America, Japan, and China. The plant itself is extraordinarily hardy. It is commonly called “Sensitive fern” because it rapidly goes dormant during summer droughts or the first signs of frost in the fall.

This fern has a long and thin, superficial creeping rhizome. Onoclea grows rapidly and forms light-green leaves on strong petioles. In spring, they turn pinkish-bronze in color. Some of the leaves can be twisted into balls resembling a pearl string. In winter, Onoclea loses its leaves. As a result, your green pet can only serve as a decoration from spring to the first frost.

How to Care for the Plant

Water
Your green pet needs consistent moisture. You should ensure it gets a lot of water. Don't let the soil dry out completely! Typically, Onoclea needs irrigation once every 8-9 days.
Pruning
This fern does not need pruning. You don't even have to remove the dead leaves of the plant.
Fertilizer
You can use nitrogen-based foliage fertilizers. The primary function of nitrogen is the formation of chlorophyll, the construction of new cells, and the strengthening of the immune system. Feed your leafy beauty once a month in winter and once every two weeks in summer.

Temperature
Although the plant's leaves are sensitive to cold, its roots tolerate surprisingly low temperatures. This tough fern can withstand temperatures down to -22 degrees Fahrenheit (-30 Celsius)! However, don't challenge your green friend. Keep the temperature in the range of 60°F-75°F (15°C-24°C).
Container
Make sure your container has proper drainage. The pot should be wide and shallow (not too tall). Plastic pots handle moisture levels better, so they will be a better choice than terra-cotta ones.
Fun fact
Onoclea Sensibilis is one of the most ancient plant species. This is why this grandma is so resistant to low temperatures!
