Arisaema sizemoreae

Section Fimbriata.

Described in 2003, Arisaema sizemoreae is a deciduous tropical species from Thailand with a single glossy trifoliate leaf and a spadix ending in a cluster of fimbriate bristles. It is an exceptionally beautiful plant.

The spathe tube is cylindrical with a wide yellowish-green mouth. Plants reach around 40cm tall.


Tubers are subglobose and reach around 6cm in diameter. Offsets are produced relatively sparingly from the adult tuber on mature plants.

Seeds and germination:

Seeds can be stored dry with no significant loss of viability. Germination has been relatively good here, but has taken longer than many species. Around 8 – 12 weeks has been typical.
