Thanks for the article and expanding my knowledge of cabbage trees

Hi Peanut! Glad you liked the article. I liked the one you link as well! Those walking-stick cabbages are very cool! I looked for more photos and among them (while googling 'walking stick cabbage') there was a mountain cabbage tree as well! Googling 'cabbage tree' I see there are many other kinds of plants called cabbage trees, including Cordylines from New Zealand, which are great, and members of the Daisy family that grow to tree proportions on Saint Helena and the Juan Fernandez islands (quite different species on the different islands though).
