Stephania erecta

Stephania is a genus of flowering plants in the family Menispermaceae, native to eastern and southern Asia and Australia. They are herbaceous perennial vines growing to around four metres tall, with a large, woody caudex. The leaves are arranged spirally on the stem, and are peltate, with the leaf petiole attached near the centre of the leaf. The name Stephania comes from the Greek, "a crown". This refers to the anthers being arranged in a crown like manner.

I have FB group about caudexes and Stephania plants: Stephania et al. 

HOW TO GROW

• Plant caudex in exceedingly well-draining soil (at least 50% perlite, vermiculite and/or pumice) with the top half of the caudex exposed. 
• During active growth, water when soil is fully dry. Stephania erecta is typically dormant from December to April. During dormancy, refrain from watering.
• Stephania erecta needs bright indirect light, adequate humidity, and warmth to grow a mature vine. Use a cloche or unsealed plastic bag to make a humid microclimate that will help initiate growth.
• This plant is extremely sensitive to over-watering. Too much direct sunlight can burn the leaves and caudex.
