It was introduced to the West from China in 1910 by William Purdom, who later travelled on an epic plant-hunting expedition through China and Tibet with Reginald Farrer, author of On the Eaves of the World.
macropetala is one of the most charming plants for a pot, either twining its way up a trellis or trailing over the rim to make a tangle of flowers and foliage on the ground. Its natural height is at most 10 feet (3 m). There is an attractive pink form called ‘Markham’s Pink’, and if your pot is large enough, you could grow the two together.

And there is a case, when planting in a pot. For acquiring some limy soil in the country, and mixing it with decayed manure orand bonemeal. For clematis are hungry feeders. Otherwise. Plant in a loam-based compost and give regular liquid feeds.
should be light, just a trimming of inconvenient shoots, and if you deadhead you will miss the silky seedheads which follow the flowers.
