Another Way To Think About “Helmet Heads”

For many, the large domes of foliage on bonsai that are popular around the world are ridiculous. The “helmet head” label is accurate enough—they look not unlike the impressive headgear of Lord Dark Helmet in the movie Spaceballs. Rather intimidating. And, top heavy.

To give the critique credit, such large domes are often out of sync with the thickness of the trunk. Large crowns are usually—if we can make a general styling statement—linked with a thick trunk. Small crowns work well with a trunk as skinny as a rope.

I have an observation about these large masses of foliage. It might not change our artistic preferences, but is perhaps something to consider.

What I’ve noticed is that trees with a lot of foliage have just that much more ballast against disease and pest. In other words, trees with more foliage are better equipped to resist an attack, and might win their way to another year.

If the above pine does get hit by a pathogen, and loses half its branches, it might still have a future. If the pine below loses half its branches, it might die.

This a tree is in my garden, a Lodgepole Pine. It takes careful management. A tree without much of a sugar engine is an unwitting liability, even under good care.

These two examples are extreme. And not a reason to avoid bunjin. Just something perhaps to consider.

Fencing over the artistic right or wrong of the helmet head is another conversation (feel free to express your thoughts in the comments below).
