This project from Designboom made my eyes pop. Wow, these are arguably the best indoor Ficus trees I have seen in a long time, maybe the best ever. Then I read that the project is in the U.K. and that they imported the trees from the Netherlands. Mystery solved. The Netherlands is head and shoulders above the rest of the world in horticultural expertise.
If I could only make just one call or email to get advice about an interior plantscaping problem or design challenge it would be to Kenneth Freeman in the U.K. He is one of the most knowledgeable interior plantscapers I know in my long experience in the field. He is an executive with Ambius, a subsidiary of Rentokil Initial plc a U.K. corporation. Ambius is the largest interior plantscaping company in North America.
When I saw the photos of these fabulous Ficus trees and noted that they were from the Netherlands, I immediately thought of Kenneth. I well remember his comments long ago about superior interior plant quality in Europe. He said that they had access to plants that are not available in the U.S.
Seeing is believing. I doubt that there is a grower with meticulously groomed Ficus trees like these even in Florida, certainly not in California.
These trees are obviously not growing in dim light that causes problems for top-watered Ficus trees in homes across the U.S. You can see the lights overhead in this view. The night shot below really emphasizes how bright the light is.
I am wondering about irrigation of the trees. It is very possible that they are planted in clay pebbles using the system called hydroculture. I will make an effort to find out and update this post.
