Fresh willow is generally available from November 
It will retain its vibrant colours for a few months before fading to more neutral tones
 
Some, as shown in the pictures, have sideshoots which can be snipped off if not needed for extra flair. The green/red-brown combo wreaths have varying amounts of sideshoots. Let me know if you would like me to select ones with lots on, in the comments box at checkout.
