The following are some pictures of my stab at growing Hemianthus callitrichoides (HC)
in my backyard over the spring and summer of 2007.
I used a couple of seedling trys from Wal-Mart filled with ADA Ammazonia AquaSoil. It was watered three times (five minutes at a time) a day via a pair of drip sprinkler spray heads. The substrate was kept moist, but not fully saturated.
Here's a closer look at the growing trays.
And here's a closeup of the HC growth. Those are grains of regular AquaSoil for size comparison.
And here's a size comparison with something probably more familiar to most. AS you can see, grown terrestrially, the HC has taken on a very dense growing pattern, nearly to the point that if you walked by and saw it with out knowing what it was you'd assume that it was some form of moss.
