Plectranthus parviflorus ?

Plectranthus species, possibly P. parviflorus

The name of this Australian native Plectranthus is something of a mystery: it seems likely that it is P. parviflorus, P. graveolens or P. suaveolens. I refer to it as Plectranthus parviflorus but am happy to be corrected! These plants are apparently hard to tell apart by non-botanists! Mine was given to me by a friend as being one of the toughest plants she had ever grown. It gets to about 40 cm tall and forms a mound. It will grow in either full sun or full shade, plus in any moisture position ranging from completely dry spot or a bog! It has aromatic, hairy leaves and seems to be covered in dainty spires of purple-blue flowers basically all year round. I enjoy seeing its haze of lovely flowers juxtaposed with the lime-green bracts of Euphorbia corallioides in a shaded part of my garden in mid-spring. Elsewhere in the garden, it consorts prettily with a lilac-pink Pentas throughout summer and autumn.

Plectranthus parviflorus Blue Spires

There is a lovely form with white-variegated leaves that is sold as P. parviflorus 'Blue Spires', which is similarly as forbearing of a range of conditions as the green-leaved version. The plants look good in a native Australian-style garden, a woodland area or a flowery border.

Flowers in January, February, March, April, May, June, July, August, September, October, November, December.
