Arisaema concinnum is a handsome plant and one that is often incorrectly identified. However, there are several features that enable easy identification:
The spathe tube is always striped and the spadix ends in a distinctive round knob showing a rough crumpled appearance. The tuber is stoloniferous. Plants will be either male or female.
The tuber is subglobose and stoloniferous, reaching around 5 or 6cm in diameter and multiplies via underground stolons. These can be quite large and typically between 1 and 3 are produced in a season. In appearance, the tuber is impossible to tell apart from Arisaema exappendiculatum, and these are commonly muddled up within the nursery trade.
Seeds and germination:
Seeds can be stored dry with no significant loss of viability. Germination is easy and typically takes around 6 – 8 weeks.
