Bonnie: I too have gotten Coal Seams as a bonus, but so far mine has really strong growth, while Slew of Gold may need some nurturing. I find though, that many of the bonus iris have been hit or miss for me. Grateful Red rocked it from day one, but Sunrise Elegy is always on life support. I may be wrong in this opinion, but I feel like the bonus iris are still in that make it or break it stage, since not all of them go on to be sold on Schreiners site.
