Rolf R. Rawé's "Caudiciforms: The Succulent Bonsai" argues that caudiciforms, plants with swollen, succulent trunks or roots (caudices), are uniquely suited for bonsai cultivation due to their sculptural potential and compact growth habit. The book provides practical guidance on selecting, propagating, and styling these distinctive plants, emphasizing techniques that highlight the caudex itself as the primary aesthetic feature, mimicking the aged appearance of mature trees in miniature.
The text covers the specific needs of various caudiciform genera, including their watering, soil, and light requirements, alongside detailed instructions for repotting, pruning, and wiring. Readers learn to appreciate and develop the gnarled, aged character of caudiciforms, transforming them into striking living sculptures that capture the essence of ancient trees.

Key concepts
- Caudex — The swollen, thickened storage organ (trunk or root) characteristic of caudiciform plants.
- Pups — Offshoots or basal shoots that can be removed and used for propagation.
- Aeration — Ensuring sufficient air circulation in the soil mix, crucial for preventing root rot in succulent species.
- Stratification — A technique used for germinating some caudiciform seeds, involving a period of cold or moist storage.
- Apical Dominance — The tendency of the terminal bud to inhibit the growth of lateral buds, a factor managed through pruning in bonsai.
