Caring and Maintenance
This is a very low maintenance plant. Propagate by seed division in early spring or autumn.
Ferns are great at improving the air quality in your garden, and they offer lush, green foliage. They can grow in low light areas and need very little maintenance, if any at all. They absorb dank water, making them great for waterside locations and slopes.
RHS Award of Garden Merit
The Award of Garden Merit or AGM is an award made to garden plants by the British Royal Horticultural Society after a period of assessment by the appropriate committees of the Society. Awards are made annually after plant trials (which may last for one or more years, depending on the type of plant being trialled) at RHS Garden, Wisley and other RHS gardens, or after observation of plants in specialist collections. This is intended to judge the plants' performance for conditions in the UK.
