I don't think that would work. As Tiffany pointed out, most alpine plants are unsuitable for her purposes. I think "suitable for miniature gardens" is a good category for addition, but I think it should say "miniature" rather than "mini" because mini garden could be misunderstood as small-space gardening.
Actually, though, while we're on the subject, I'd like to change "Alpine/Rock Gardening" to "Alpine Gardening" because just about any drought-tolerant plant can be grown in a rock garden, whereas alpine plants have to meet a set of highly specific criteria.
@growitall and I have done quite a bit of work to keep anything not meeting those criteria out of that category.
