Fun Facts
- 🌱 Kimberly Queen Ferns are named after a plant hunter's discovery in the Queensland rainforests of Australia and have been cultivated as houseplants since the 1970s.
- 🌱 Unlike Boston Ferns, Kimberly Queens naturally grow upright rather than cascading, making them one of the few ferns suitable for floor placement rather than hanging baskets.
- 🌱 Ferns reproduce via spores rather than seeds; the dark brown spots on the undersides of fronds are fertile sori (spore clusters) that can be used to propagate new plants.
