Dioscorea elephantipes (Elephant's Foot) appraisal
The caudex's beautiful cracked pattern resembling a tortoise shell is its defining feature. This caudex plant has a unique cycle of winter growth and summer leaf-drop dormancy. The beauty and plumpness of the caudex pattern are the core of appraisal.

What determines the price
Clarity of the tortoise-shell crack pattern on the caudex
HighThe clarity and uniformity of the hexagonal crack pattern resembling a tortoise shell on the caudex surface is the prime viewing point. The more uniform the pattern, the higher the appraisal.
Caudex Size and Plumpness
HighLarger, well-filled caudex indicates more years of cultivation, increasing rarity. The balance between caudex size and pattern clarity is important.
Vine and Leaf Condition
MediumDuring the growing season (autumn–spring), vine and leaf vigor are health indicators. Leaf-drop during dormancy is normal physiology.
Understanding the Dormancy Cycle
MediumLeaf drop during the summer dormancy period is normal physiology for this species. Evaluation based on understanding purchase timing and dormancy cycles is important.
Appraisal points
Verify the turtle-shell pattern on the caudex

- Good:
- The turtle-shell pattern on the caudex surface is sharp and well-defined, with uniform cracking across the entire surface.
- Caution:
- If the pattern is unclear or broken, this is individual variation. Evaluate together with the overall form at purchase time.
Verify the firmness and condition of the caudex
- Good:
- The caudex has firm, solid structure with no excessive softness or wrinkles.
- Caution:
- If the caudex is soft or has excessive wrinkles, water deficiency or root problems may be present.
Verify the purchase timing and growth cycle
- Good:
- When purchasing during the growing period (autumn to spring), vine and leaf vigor can be confirmed.
- Caution:
- Leaf drop during summer dormancy is normal. When purchasing during dormancy, emphasize checking the caudex condition.
