Grand Duke Plant - Knowledgebase Question

I am looking for planting & maintenance instructions for a gardenia-like evergreen plant called "grand duke". My mother had some 50 years ago and I have acquired some cuttings from my sister -- she said mom said it was a "grand duke". It has a very fragrant small creamy white flower and the plant grows on a trellis. It looks and smells something like a gardenia. The flower is compact about the size of a half dollar. I hope this information is helpful - that is all I know about it. Thanks!

You might be referring to a type Arabian jasmine, Jasminum sambac flore-pleno, also known as Grand Duke or Grand Duke of Tuscany. Native to southeast Asia, this is an evergreen shrub with a climbing habit, and has double white, fragrant flowers.

The plant prefers fertile, well-drained soil in full sun or with some light shade during the hottest part of the day. Provide a trellis for support, and as the plant grows tied it to the trellis if necessary with a soft plant tie or piece of fabric. The plant generally grows up to five feet tall. There's no need for annual pruning, but from time to time you can thin out the oldest or most crowded stems. I hope this helps!
