Osmanthus fragrans (Oleaceae)
This shrub from China and southern Japan scrapes into the top twenty best perfumed plants for the delicious intense ripe apricot scent which is released from the very small brownish white flowers. It can be elusive though as when I stuck my nose up close one afternoon last week I could barely detect a fragrant note. No doubt it is timed to deal with the appearance or not of a suitable pollinator. When not in flower it can be a bit of an unappealing and straggly shrub with tough leathery olive green leaves and growing from 3 to 5 metres; so the suggestion would be to plant it in groups of 3 or more or merge it with other shrubs in a border. It would be useful to plant in one of those narrow corridors between buildings which get zero sun in winter as it will tolerate some shade though I have seen specimens grown in exposed windy positions suffering dreadful leaf scorch. Most plants available in the nursery trade are sold in 140mm/6inch pots as it can be slow growing.The common name for it of 'Sweet Olive' is just too confusing as some punters may imagine that it belongs in a martini glass.
