This is an attractive reddish brown plant. It's popular plant, and often used as a centerpiece for an aquarium.
B. longifolia requires strong lighting. I have, in the past, had several plantlets grow off of the main plant shown in the photo. They continued to grow after being broken off and planted away from the main plant.
The plant in the picture at left is surrounded by Rotala, Red hygro, Mexican oak, hairgrass, Cryptocoryne nevillii and a bit of hornwort at the top right.
Unfortunately I don't have any of these any more. They need more care than many aquariums plants. And don't do well without regular water changes and pruning of plants around them.
