A highly interesting and recommendable ground-covering plant that's still a rarity. It was collected on a riverbank in the province Misiones in North Argentine by some Japanese, and it was named after the place where it was found: Micranthemum sp. "Montecarlo-3". This plant is also known under the name "New Large Pearl Grass", and in South America as "Bacopita". It looks like a larger version of Hemianthus callitrichoides, but it is also somewhat similar to "standard" Micranthemum umbrosum. It grows flat on the ground, forming a compact mat. The roundish leaves are a bit smaller and of a darker green than those of M. umbrosum. When planted in an elevated place, loose shoots will bow to the ground. This Micranthemum is easier in cultivation than Hemianthus callitrichoides.
You are buying one mat that is a minimum of 3 inches x 5 inches and full of Micranthemum Tweedie sp. Monte carlo, see the picture.
Mats that have plants attached should be planted by burying just the bottom of the mat in your substrate. The top of the mat with the plant should not be buried at all. The best way to do this is to carefully move the mat back and forth as you push it down in your substrate. The weight of the mat itself and having it in your substrate should hold it in place. If it does not stay in place, you can add plant weights to the bottom of the mat by inserting them into the mat. Click HERE to View the weights.
