Hoya krohniana 'Black Leaves' D6

Hoya krohniana 'Black Leaves' is a label for a selection with dark foliage. The small, glossy, heart-shaped leaves turn burgundy or almost black in bright light. The color is not produced by a stable black pigment. The species is native to the Philippines and was published in 2009; it previously circulated as Hoya lacunosa 'Heart Leaf'. Its growth habit is compact and trailing. The flowers are small, creamy white, fluffy, and fragrant, resembling those of the lacunosa group. This is a small pot, suitable for a young plant.

Foliage and growth. New leaves are often cordate; mature forms may vary. The dark color depends on light: in low light, the foliage returns to green. The species may also develop silver splashes. Shoot length varies from one specimen to another.

Flowers and fragrance. The flowers are star-shaped, finely pubescent, creamy white, and arranged in umbels. The fragrance is strong and perceived especially in the evening, as with Hoya lacunosa. The flowers last for several days. Flowering depends on the plant's maturity and growing conditions.

Identity. The accepted botanical name is Hoya krohniana Kloppenb. & Siar, published in 2009. The species is native to the Philippines. 'Black Leaves' is a label for the dark foliage. It is not Hoya lacunosa, although the flowers and growth habit are similar.

Potting mix: use an airy, well-draining mix suitable for epiphytic species. We recommend the professional potting mix for Hoya and Anthurium - SG Mix.
