Garden origin plant, seedling of Prostanthera 'Snow Queen'.

Has thin, mid to deep green leaves that have a menthol scent. Bears innumerable small, white flowers with spotted yellow throats which almost hides the foliage.

Flowers in summer.

Loves a well drained soil and likes a little shade during the hottest part of the day but it won't grow in shade. Not terribly frost hardy so best brought in undercover in cold regions for winter.
