Kalanchoe millotii Raym.-Hamet & H.Perrier
Millot Kalanchoe / Velvet Leaf Kalanchoe
Kalanchoe millotii is a compact succulent shrublet native to Madagascar, recognizable by its fleshy grayish-green leaves densely covered in minute white hairs that give it a soft texture and a snowy or silvery appearance. Its scalloped margins and compact size make it ideal for succulent collections indoors and in warm outdoor settings.

Origin & Habitat
Morphology
Ovate to orbicular leaves up to 6.5 cm long, fleshy, green to grayish-green, densely covered with minute white trichomes on both surfaces; crenate-scalloped margins; do not produce adventitious plantlets like some congeners.
ecoErect stems, woody at base, with well-defined lateral branches; the white hair covering extends to young stems as well; typical height 30–100 cm.
ecoSmall, greenish-yellow to orange-yellow flowers with farinose-tomentose calyx; appearing in summer in loose spikes up to 10 cm; the main ornamental value is the foliage.
ecoFibrous, shallow root system; the plant grows well in relatively small pots given its moderate growth rate.

Propagation Strategy
- 1 Cut a 5–8 cm stem with clean scissors.
- 2 Remove lower leaves; K. millotii is compact, handle cuttings carefully.
- 3 Callus for 1–2 days.
- 4 Plant in draining mix; water after 7 days.
- 5 Rooting in 2–4 weeks.
- 1 Remove scalloped, hairy leaf with complete base.
- 2 Callus for 2–3 days.
- 3 Place on moist mineral substrate at 22–26 °C.
- 4 Emerging plantlet in 6–10 weeks.
WARNING: toxic to dogs and cats. The small scalloped hairy leaves are the main ornamental feature.
Overwatering a small-statured species that can rot quickly.
Every 1–2 years in spring in a small pot.
Balanced fertilizer at 50% monthly from March to September. No fertilization in winter.
Uses & Applications
Precautions / Toxicity
TOXIC to dogs and cats; like all Kalanchoe, contains cardiac glycosides that can cause vomiting, diarrhea, heart rhythm abnormalities, and neurological signs if ingested in sufficient quantity.

"K. millotii is one of the least-studied tomentose Kalanchoes; its white trichome coverage on both leaf surfaces (unlike the one-sided or patterned coverage of K. tomentosa or K. orgyalis) suggests extreme xeric adaptations in its native Madagascan microhabitat, though detailed characterization of its trichomes and secondary metabolites remains sparse in scientific literature."
