C. acuminata var. sikkimensis Brühl.©Ton Hannink The bell flowers of Clematis acuminata var. sikkimensis are white/creamy yellow, between 20-30 mm long and 15-20 mm in diameter. The flower has 4 tepals.

The flowers are from November - February in the wild but in Europe the plant has flowers in January and February. The small white flowers in winter and the evergreen leaves makes the plant very attractive. The seeds are ripe in May - June.

The stems grow to 3-6 meters and is therefore a rather big clematis if you want to keep the plant in the greenhouse. The plant is evergreen.

C. acuminata var. sikkimensis Brühl.©Ton HanninkThe plant prefers acid, neutral and basic (alkaline) soils. In Holland the plant is probably not hardy and therefore I keep my plant in a container in the greenhouse in winter. The plant has been kept outside in 2009/2010 in England. If you keep the plant in a pot then you must renew the soil almost every year and during summer, the plant needs fertilizer every week and chelated iron every month. During the flowering period the plant must have enough water and fertilizer. If planted in the garden, you should plant C. acuminata var. sikkimensis somewhere that is dry in winter, otherwise you will probably loose the plant.

The plant can be used for a pergola, obelisk or trellis in the garden. The best place is on the west or south sides of the garden so that the plant becomes not so cold, or on the south wall of a house.

Pruning is only needed if the plant is too big.

Propagation by cuttings is not too difficult but is the best at about 23 degrees Celsius. Propagation from seeds is also possible.
