Acer palmatum ‘Seigen’ — Characteristics & Bonsai Use
The cultivar has a semi-dwarf, upright growth habit with medium vigour and medium-length internodes. Leaf size is moderate, well suited for bonsai proportions. Bark is smooth throughout development, showing light green with distinctive red and pinkish tones — an unusual trait that adds visual interest even during the leafless season. In open ground, ‘Seigen’ reaches just 1 to 2 metres, keeping proportions naturally compact.
For bonsai purposes, the combination of moderate growth, manageable internodes, and extraordinary spring colour makes ‘Seigen’ particularly well suited for shohin and display-oriented compositions where colour is the primary design feature.
- One of the rarest Acer palmatum cultivars, with a very intense light red to almost purple spring flush that few other varieties can match.
- Semi-dwarf upright habit with medium internodes, ideal for shohin and display-oriented bonsai.
- Delivered at a minimum height of approx. 15 cm measured from soil line to apex.

Feedback from growers

Translated from Italian
This bonsai had quite a story. It arrived in poor condition, not due to the seller but because the courier took longer than expected. Treevaset was extremely helpful and immediately available to resolve the situation. Highly recommended. I’ve purchased from them multiple times and I will definitely do so again.

Translated from German
Friendly communication and fast delivery. At first, it wasn’t clear to me that the seller ships from Italy, which made me hesitant when ordering plants. However, the plants arrived in excellent condition thanks to very careful packaging.

The courier was delayed, but the plant arrived healthy thanks to excellent packaging. A very promising larch with good movement and already well-developed foliage. It has a subtle literati-style character that can be further enhanced. It deserves a proper, well-chosen pot. Very satisfied.
