Last summer when I went to Paris, CHM had taken some cuttings from a winter jasmine plant that grows in his little back garden. I brought the cuttings back to Saint-Aignan and planted them in a big pot.
When winter came, all the leaves on the stems dropped, and I was afraid they all were dead. I just left the pot out on the terrace for the winter (or what passed for winter this year, which was very wet but not very cold).
Now, however, the stems are sprouting a lot of new leaves, so the plant has survived. It didn't flower over the winter, which it would have normally been expected to do, but maybe we'll get flowers next year.
The winter jasmine, or jasmin d'hiver (Jasminum nudiflorum), usually produces yellow flowers between November and February, making it one of the few plants that flower in winter in this climate.
