Perfume that doesn’t attract insects would be a horticultural oxymoron: putting out the come-hither for pollinators is a flower’s sole purpose, and perfume is a large part of the mating dance. However, not everyone wants to sit in a garden when the bees and other pollinators are moving around, and you can have a fragrant garden that’s low on bees by using night-blooming plants.
Choices range from the small, inconspicuous, but mightily perfumed annual known as night-blooming stock (Matthiola bicornis) to the many cultivated varieties of Brugmansia, a tropical tree that can grow to 10 feet or more and has been showing up in nurseries under the name angels’ trumpets. All parts of the brugmansia are highly poisonous, but there’s no denying the plant’s appeal. It’s huge flowers blare tropical sweetness from dusk until almost sunup. White is the most common color and usually the most fragrant, but brugmansia also comes in yellow, orange, peach, and pink. Like Chinese hybiscus, mandevilla, and the many other tropicals sold by nurseries in temperate climates, brugmansias are not frost hardy and must be overwintered indoors.
If you want to stick to annuals, there are plenty to choose from — nicotiana, for example. You’d never know it from the modern cultivars, which lost fragrance when they were bred to stay open during the day, but old-fashioned flowering tobacco (Nicotiana alata) has a very strong night perfume, and so does its much taller, architecturally splendid cousin N. sylvestris.
Other candidates include moonflower vines, night-blooming jasmine, evening primrose, and oddball day lilies like ‘Pardon Me,’ which don’t get going until the sun goes down.
