Blue Oil Fern

Medium to bright indirect light brings out the blue iridescence most vividly. A north- or east-facing window works well. The shimmer fades in very low light. Avoid direct sun which bleaches and scorches the delicate fronds.

A grow light is worth considering for this plant in Canadian homes during the short-day months of October through February. The blue iridescence is directly tied to adequate light. Without enough, the fronds look standard green and the unique shimmer disappears.

Water when just the top centimetre of soil feels slightly dry. Every five to seven days in spring and summer, seven to ten days in a Canadian winter. Never let it dry out completely. The fronds lose their shimmer and tip colour when the plant is drought-stressed.

Needs humidity above 60 percent to maintain the iridescent shimmer on the fronds. The dry forced-air heating in Ontario and Quebec homes is the biggest challenge for this plant. A humidifier nearby, a pebble tray, or growing it in a terrarium are the most effective solutions from November to March.

Not listed in the ASPCA database by name. The live page describes it as non-toxic, but this is not verified. Keep it out of reach of pets and small children as a precaution.

The blue iridescence that makes this fern a collector piece depends on adequate light. From October to February when Canadian daylight drops to six or seven hours a day, even a south-facing window may not be enough. A small full-spectrum grow light placed nearby for eight to ten hours a day keeps the fronds vibrant and the shimmer visible through the entire Canadian winter.
