Another one of the "oldies but goodies" we use to grow (not as Elizabeth clarifies "use to sell" - because it was rarely bought). But my dabbling propagation efforts escapes the hydrangea genus and so. . . This is native to China and sprawls in a mass array of "semi-climbing green shoots" (Graham Stuart Thomas). Dark green leaves and small trumpet-flowers in threes at the leaf-axil that are pinkish. It is sweetly scented and suitable for zones (7?)8 - 10. Height is determined by how well trained onto a supporting structure it is. A quick grow in a warm site.
For a much different opinion here’s a quotation from a gardener in the U.K.: "those who describe Jasminum beesianum as a must-have with scented red flowers should be strung up by the thumbs. Only when it has legged-it messily up to the gutters will it produce a few deeply insignificant flowers the size of pin heads whose scent is practically indiscernible."
Roll of the dice. Maybe that’s why we never sold many!
