Richjam, I know what you mean. I love raising and growing stuff. There's something special about doing it yourself. I also breed birds. Been hooked on that since the 90's. I LOVE ventricosas but don't have any. Would love to get some seeds of those.
Kula, don't both types of truncatas over lap in range? I think you can tell them apart visually. The lowland isn't as nice looking. But it will be a long time before I can tell with mine.
