Is the Asparagus Fern toxic?
Yes, Asparagus Ferns have small needle-like structures in their stems and leaves that can cause an itchy mouth and inflammation if eaten. Adult Asparagus Ferns develop small red berries that should not be eaten as they contain the toxic saponin sapogenin which can cause upset stomach and vomiting. It is not recommended that you let pets eat any part of an Asparagus Fern. It is also recommended that you be cautious about having Asparagus Ferns around small children because ripping and tearing at the leaves can cause irritation on the hands.
What’s the ideal temperature?
Asparagus Ferns are resistant to short bursts of temperatures as low as 20°F but prefer temperatures around 70°F. If you live in an area with long exposures to temperatures below freezing consider keeping the plant indoors or in a pot that you can bring indoors during the winter. Asparagus ferns will tolerate hot indoor temperatures and will slow down growth in the winter when there are less daylight hours and colder temperatures. Due to their large root systems Asparagus Ferns that have been burnt by frost can regrow from their roots in the springtime.
What’s the ideal humidity level?
Household humidity is more than adequate for Asparagus Ferns, their natural range includes many locations with low relative humidity and despite the delicate appearance of the leaves they are tolerant to low humidity conditions. In some cases household humidity in winter may be low enough to cause drying out of the leaves, and when this occurs consider raising the humidity of the space to resolve the issue. Asparagus Ferns do benefit from light misting and localized humidity near the plant may influence where vining occurs as Asparagus Ferns prefer to vine towards more humid locations.
Does it purify the air?
Does it purify the air? Asparagus Ferns are considered one of the best indoor houseplants to purify air. They come highly recommended from several sources and have even been evaluated by NASA. Their diffusive leaves allow them to take up a large amount of indoor air and their spreading habit allows for a large amount of greenery from only one pot. If vines are allowed to spread sufficiently one plant can be a feature of more than one room in a house. When growing Asparagus Ferns for air purifying quality, clean the leaves often to keep the surface of the leaves dust free and it will maximize how well they clean the air.
