H Citrina: I am told this has been used as one of the food stables in China and has medicinal use as well. Long re-blooming plant, hardy. Slighly fragant, don't need much water and still can survive, can grow on slope and good for xeriscape. Propagation by division of roots. Shrubs 24-30 inches tall.
The Chinese gathers the flower buds (about 6 to 7 inches long, pale greenish yellow), and use for cooking in fresh form, or dry (dehydration) for soup and steam with or stir-fly with pork/chicken/fish etc.

This is a wonderful Hem. that I planted beside my steps going up to my garden shed - so I can smell its wonderful fragrance when I pass by it! Mine doesn't stay in bloom as long as I'd like, but it's a keeper!

This species has done very well for me in Zone 8b Florida. It is a hard Dormant, and is late to break dormancy, but then grows fast and blooms heavily. The foliage has a blue tint to it, which is an another plus.
The flowers open in the evening, and close the middle of the next morning. They are extremely fragrant. I have seen Hummingbirds visit the blooms.
