Rainy Side Notes
Anyone that observes Asian lady fern during spring cannot help but fall in love with it. Its fresh new fronds contrast against the red-maroon stems. It is distinctive looking during the entire growing season. It dies down to the ground after first frost in fall, and re-emerges in spring.
A. otophorum 'Okanum' won the Award of Garden Merit from the Royal Horticultural Society.
