Leon, thank you very much for this insightful post.
I am very much looking forward to my MDB and my SDBs blooming and prospering. I really do not mind an iris that is prolific. I want that. I want my yard blooming with as much as I can, so if it is floriferous, that is certainly fine by me. That means more transplants and more trades!
Those images show really how tiny MDBs and SDBs are. I sure hope mine do well. Thanks for that awesome post, Leon!
