Agave ovatifolia (Whale's Tongue Agave) appraisal
A large species characterized by broad, blue-gray leaves covered with white powder (bloom). Because serrations are less conspicuous, leaf width, bloom preservation, and symmetry become the focus of evaluation.
What determines the price
Bloom (white powder) preservation
HighThe waxy white powder (bloom) covering leaf surfaces is difficult to recover once it peels off. With minimal handling, specimens with evenly preserved bloom receive higher evaluation.
Leaf Width and Fullness
HighThe broad leaves derived from the cultivar name are the greatest characteristic of this species. Plants with uniform leaf width and rosettes that spread evenly throughout are valued for their fullness.
Rosette Symmetry
MediumThe higher the symmetry of the entire rosette, the higher its ornamental value. Leaf asymmetry or partial leaf loss may indicate issues with growing conditions or transport.
Plant Size and Fullness
MediumThis species becomes large when mature. Large specimens developed over many years of cultivation are rare, and fullness directly impacts evaluation.
Appraisal points
Check for Uniform Bloom
- Good:
- Bloom is uniformly distributed on the leaf surface with minimal handling marks.
- Caution:
- Plants with bloom removed through transport or handling have reduced aesthetic value.
Check Leaf Expansion and Shape
- Good:
- Leaves expand broadly and flatly, spreading evenly from the rosette center.
- Caution:
- Leaves that curve upward or curl inward may indicate insufficient moisture or environmental stress.
Check plant base and rooting
- Good:
- The plant base is stable and does not shift within the growing medium.
- Caution:
- Unrooted propagated cuttings require additional time to establish roots, so care is needed.
