Plant Details

An excellent and unusual ground cover plant from New Zealand and rarely seen here. Small, white, scented flowers in summer. 

This hardy little plant is excellent and all but unknown in the UK. Useful for underplanting large containers or as ground cover. It is now even being used as an alternative to grass in some countries.

Its vibrant, light green colour makes an expanse of Selliera a beautiful sight; one which is further enhanced by the appearance of its copiously-produced white flowers in summer.

Can cope with coastal positions well and seems to be fine in wet or very dry soil, and anything in between.

Height: 10cm 

Common name(s): Bonking Grass; Victorian Swampweed; Tongue Plant.

Regarding the origin of the intriguing name Bonking Grass, we are grateful to retired nurseryman Geoff, from Auckland New Zealand for the following information:

"Living in West Auckland at Oratia I employed staff from around the western suburbs extending over the Waitakere Ranges (Auckland’s water supply area covered in native forest) to the West Coast beaches bordering the Tasman Sea, including Piha. It is the most populated suburb with rugged cliffs and black sandy beaches both of which are pounded by rough surf, making it a surfers destination.

High above one portion of the cliff called the ‘Blow Hole' there is a flattish area of land locally named the ‘Tennis Court’ because of the closely cropped coastal turf that grows there. One of the main components in the turf is Selliera radicans and it is the smooth cool texture of its foliage that makes the area so attractive for picnics and perhaps tennis. Of course such a private and remote site provides opportunities for more intimate activities, and the nick-name for Selliera became ‘Bonking Grass’. It is not a grass at all, but a flowering dicotyledon, as are most of the other species making up the coastal turf."

All our plants are supplied in 9x10cm pots unless otherwise specified. Plants in this size pot establish quickly in the garden and often outpace plants in bigger pots planted at the same time. We do not sell 'plug plants' because those need to be grown on before planting. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant. We grow everything we sell ourselves, in our nursery in the Buckinghamshire countryside.
