Dwarf Baby Tear – Hemianthus callitrichoides – Smallest of all Baby Tear plants, medium green in color, teeny tiny leaves. Ships out less than 1/4″ tall, and will not likely grow any taller, however, it is a moderate spreading plant. Ideal for foreground or filler.

Lg Mats are appx 10 to 12 inch square, and small mats are appx 3×5.
Giant Baby Tears – Micranthemum umbrosum – Exact same growing habit as Dwarf Baby Tears, except Leaf is more of a rounded and larger size leaves, and Bright Green in color.
