Are you looking for an unusual subshrub for the fall garden? Elsholtzia stauntonii is a good choice. The Chinese mint shrub is rare in northern gardens, where its late flowering is very much appreciated.

It is hardy down to zone 4, but in that zone you might never see it flower. Even in zone 5, an early frost may result in poor flowering or even no flowers at all. But it is worth taking a chance since so few other shrubs flower so late in the season.

Many people call it a shrub. Is it a shrub or subshrub? Botanically there is no difference between the two terms. The term subshrub is used more frequently for small shrubs, or bushes. In zone 5,  Elsholtzia stauntonii dies to the ground most  winters and therefore only reaches a height of about 75 cm (2.5 ft); a subshrub. In warmer climates it can reach 180 cm (6 ft) – more shrub-like.

Elsholtzia stauntoniiis is also known by other common names including mint shrub, peppermint tree, and the Chinese spicebush, each referencing its very strongly scented leaves. A white flowering variety is also available.

The plant shown in these pictures was easily grown from seed at Aspen Grove Gardens.

I live in southern Ontario, Canada, zone 5 and have been gardening a long time. Besides writing and speaking about gardening, I own and operate a 6 acre private garden called Aspen Grove Gardens which now has over 3,000 perennials, grasses, shrubs and trees. Yes–I am a plantaholic!
