Very beautiful. I love vertical gardening pics! But how long will the plants stay so beautiful and healthy? Some weeks, months? They will grow in direction of the light. Maidenhair fern is spoilt, care-intensive and will not excuse any care-mistakes. In USDA-zones lower than 10 maidenhair is difficult to pull through the cold season. Do you have any positive experiences with maidenhair? If yes, then pls. tell me!
