I am currently thinning out my collection to make more room for them. Tissue culture possibilities for this plant could be great. I have around 8 different hybrids and they are wondeful plants to grow in terrariums or as a well placed houseplant. They flowers aren't that spectacular unless you have a large cluster of Ludisia and they they look like fireworks going off.
I strongly suggest adding a few to your collection! You won't be sorry you did. Macodes have wonderful leaves.
Hope this helps you decide on getting some
I have some good pictures of them i'll post soon
