Prostanthera phylicifolia

Spiked mint bush, Prostanthera phylicifolia, is native to Australia, and bears rosemary-like, mint-scented leaves and beautiful pink-purple blooms in late spring and early summer. Tender, spiked mint bush is best grown in the greenhouse or in containers on a sunny, sheltered patio where it can be taken indoors in winter. 2-3 ltr
