Varieties

There are two varieties:[2]

  • Osmanthus heterophyllus var. heterophyllus. Leaves entire or spiny; flowers with short corolla lobes 2.5-3.5 mm long. Throughout the range of the species.
  • Osmanthus heterophyllus var. bibracteatus (Hayata) P.S.Green. Leaves always entire; flowers with long corolla lobes 5 mm long. Endemic to Taiwan.

Nomenclature

Osmanthus is derived from Greek and means 'fragrant flower'.[7]

The scientific name heterophyllus, "different leaves", refers to the variation in leaf shape between spiny and entire. The common name holly osmanthus refers to the similarity in leaf shape to that of the holly (Ilex aquifolium), an example of convergent evolution with a common objective of deterring browsing; the two may be distinguished easily by the leaf arrangement, alternate in Ilex aquifolium and opposite in Osmanthus heterophyllus.

Cultivation

‘Goshiki’, Cranford, New Jersey

It is widely used as a

hedge plant.[6][8] Several cultivars have been selected for garden use, including 'Aureus', 'Goshiki', 'Purpureus', 'Rotundifolius', and 'Subangustatus'.[6] The cultivars 'Goshiki',[9] 'Variegatus'[10] and ‘Purple Shaft’ have gained the Royal Horticultural Society's Award of Garden Merit.[11]

The species has been hybridised in cultivation with Osmanthus fragrans; the resulting hybrid is named Osmanthus × fortunei Carr.[6]

Historical mentions

It is mentioned twice in the

gender.[8][16]
