Chrysanthemum bonsai are very popular in Japan, and like azalea bonsai, they often have their own exhibits. Although we may think of them as Japanese, the plant is originally a native of China.
These bonsai plants are not as popular in western culture, as they are in Japan. One reason may be that they are, in general, short lived plants.
Quote from - The National Chrysanthemum Society
Chrysanthemum (often referred to as “mums”) are woody perennials.
Although most seem to live as few as 3-4 years as bonsai, there have been some known to be 20-25 years old.
Another reason for their lack of popularity may be, mums are photoperiod plants. (They bloom during months with short nights.) In order to show the flowers, the exhibits are held in the Fall.
Most other bonsai are not blooming at this time ... a good reason for Chrysanthemum only shows.
Mums lend themselves to being trained into many different forms,
including topiary. It's a little tricky to wire them, however, it can be done.
As you can see on this page, many bonsai styles can be created from mums (especially after a little experience.)
The mum bonsai shown here was created by John Capobianco.
The roots are actually growing on a piece of wood, which makes the composition look like an old flowering tree.
When John Capobianco sent me photos and article about his mum slab
planting, I knew I wanted to add Chrysanthemum bonsai to this site. I
also heard from Dale Cochoy with an equally fascinating club project.
Both articles are thorough. If you have an interest in mum bonsai you will derive valuable information about styling, varieties and care from both of them. (And ... enjoy even more photos.)
