Leptospermum riparium is a broadleaf evergreen shrub with green foliage. In spring and summer white flowers emerge. Grows well with sun and regular - low water. Does well in well-drained soil.
There's not a lot of information out there on this rare species from the interior of Tasmania (and possibly mainland Australia?); in fact, this may be its first introduction to cultivation in the US. It has white flowers of average size for the genus, and so far (for us) the leaves, which are normally a dark glossy green, assume an appealing burgundy color during winter. It certainly tolerates, and may prefer, moist conditions; and should probably be hardy to at least 10 °F once established.
