I'm not sure where Alsou originated, but we got our seed from Germany. This is another heart shaped tomato and the more we grow hearts the more we love them. This is a new introduction for us this year and this tomato is not available anywhere else. It has the sweet meaty flavor that is typical of most hearts. Good grower and producer and can make some really big tomatoes if you get a fused blossom as can be seen in a few of the pictures. Give this one a try and let us know what you think.
