We have some lavender plants in our garden. Every fall the plants seem to die. All the blossoms wither and the twigs shrivel. Thus, we trim them usually. But, we start trimming not earlier but the blossoms are withered.
This year this particular plant (although we have it already for some years) wasn’t interested to stop blooming. Even in December, when we got some snow, they didn’t stop. And now, in February, they are still blooming. What a surprise!
