Growing Tips: The plant grows in wet to dry soils and sand, loam, or clay soil types with a pH range of 3.7 to 6.8. If not controlled, rampant growth can become a problem. Vines should be thinned throughout the growing season and cut back in winter to prevent aggressive spread.
Typically propagated by cuttings, it readily roots and develops new suckers that allow the species to grow rapidly.
Seeds are prepared for germination by stratifying them in moist sand for 60 days at 40°C and 30% relative humidity.
