In the typical or 'T-Form' as it is known, the upright leaves bifurcate to produce a once branched sticky leaf to about 25 cm. 
Other forms are var. dichotomawith 4 points to it's leaves, var. multifida with 8-12 points, and var. multifida f. Extrema with anything up to 40 points.
This latter forms a stunning plant with deep maroon leaves, best kept in a hanging basket to allow the heavy leaves to dangle in the air like rigid spider webs. All forms appreciate full sun and a winter minimum of minus 5 celcius (22 degrees fahrenheit), with the exception of f. extrema which although will tolerate such lows, takes much longer to re-grow from it's roots in the spring. Therefore a minimum temperature above freezing is preferable for this plant. All like full sun, and keep wet in summer, damp in winter when they die back completely.
