Arisaema flavum tibeticum

Section Dochafa.

Arisaema flavum tibeticum is found at the Eastern end of the rather wide distribution of Arisaema flavum. It is a distinct form and has several notable differences compared to regular forms of this species. 

Depending on who you ask, this is either  considered as a subspecies of the parent species, or a varietial form. Whatever its taxanomical position, it’s a superb plant that deserves it’s own page on this website. 

Reaching around 60cm in height, the immediately obvious difference between this and the regular form of Arisaema flavum is the bright yellow and rather long spathe limb extending over the mouth of the spathe tube.  This beautiful inflorescence appears just before the foliage unfolds, rather than after the leaves in the regular form. Forms are known to exist with dark blotching inside the spathe, or with pure yellow colouring.

Rather importantly, the spadix is either male or bisexual, and capable of reverting between the two depending on the size and maturity of the tuber. Sessile offsets are produced from mature tubers, these tend to slough off with the remains of the old tuber at the end of the growing season.

Young plants will produce a single leaf, whereas larger ones will make two or three leaves. Each has a well developed rachis and up to 11 leaflets, although 7 leaflets are more common. The central leaflet is always the largest, decreasing in size outwards.

Easily grown in pots or in the ground in a well drained soil. Arisaema flavum tibeticum seems to enjoy much more sun than many other species.


The tuber is subglobose. It appears to be flowering sized at a surprisingly small size of just 2.5cm in diameter. I am unsure of the maximum tuber size, but would expect around 7cm. Offsets are made around the parent tuber

Seeds and germination:

Seeds can be stored dry with no significant loss of viability.
