Buy Agastache Plants — Fragrant Perennials for Australian Gardens

About

Agastache (also known as hyssop, anise hyssop, or giant hyssop) are among the most rewarding perennials you can grow in an Australian garden. These long-lived, low-maintenance plants produce tall, architectural spikes of densely packed tubular flowers from spring through to late autumn — in shades of deep violet-blue, raspberry, orange, apricot, and coral pink. At Online Plants, our horticulturists have carefully selected varieties proven to perform across Australian climate zones. Whether you garden in Melbourne's temperate conditions, Sydney's humid subtropics, Adelaide's dry Mediterranean summers, or Brisbane's warm climate, there is an Agastache variety suited to your garden. Why Australian Gardeners Love Agastache Exceptional drought tolerance. Once established — usually within four to six weeks of planting — Agastache require minimal watering. They are built for Australian summers, thriving in heat and well-drained soils where many other perennials struggle. This makes them one of the most water-wise choices for a sustainable Australian garden. Long flowering season. Few perennials match Agastache for sheer flowering duration. Blooms appear from late spring and continue well into autumn — often four to five months of continuous colour. Regular deadheading throughout the season encourages even more blooms. Fragrant foliage. Crush a leaf and you'll discover a delightful aniseed-mint fragrance. Plant Agastache along garden paths and borders where you'll brush past them daily. The aromatic foliage also acts as a natural deterrent to deer and rabbits. Edible flowers and leaves. Both the flowers and leaves of Agastache are edible. The leaves carry a sweet aniseed flavour and can be brewed as an herbal tea, added fresh to salads, or used to infuse syrups and dressings. The vivid flower spikes make a stunning, edible garnish for summer dishes and cocktails. A magnet for native Australian wildlife. Agastache are exceptional pollinator plants.
