Ophthalmic[46, 61, 109, 174]. The flowers are an aromatic digestive tonic[238]. A decoction of the flower buds is an esteemed emmenagogue in China, their use is therefore contraindicated for pregnant women[218].

Cultivation details

Best grown in a warm position in a moderately rich free soil of an open texture[1]. The branches are brittle so a sheltered position is required[200]. Very tolerant of atmospheric pollution[200]. Hardy to about -10°c[200]. The fleshy roots are easily damaged and any transplanting is best done during a spell of mild moist weather in late spring[182].

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Stored seed must be kept cold over the winter and should be sown in late winter in a cold frame[200]. The seed usually germinates in the spring but it can take 18 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in a cold frame or greenhouse for at least their first winter. They can be planted out into their permanent positions when they are more than 15cm tall, though should be well mulched and given some protection from winter cold for their first winter or two outdoors. Layering in early spring[200].

I have planted this tree in Kansas City (Zone 5) and has survived 2 winters, one was a brutal one. It is my most beautiful tree. It is 10' tall and growing very well. Time will tell if it is 100% hardy for me, but no damage so far!
