Very fast growing, it covers everything on it's way and looks weedy.
Two years now it refuses to flower in the summer and it flowers very late autumn. Last year it started flowering in November, but cool weather destroyed it's flowering (the flowers were very small indeed and also NOT fragrant - they say it depends on the seed). I didn' t enjoy it at all and i'm thinking of getting rid of it, but i gave it another chance, still late September and not one flower! It can survive light frost.

Woody twiner native to India and Sri Lanka. Flowers are white 2 inches wide and very fragrant. Fast growing in full sun. Excellent container, garden and hanging basket plant. Soft green foliage, the vine will flower all summer and will easily train up a trellis or fence.

Fragrance varies by plant: grow rooted cuttings of known plants for consistent results.
