Growing Tip:

Plant in a sunny spot with excellent drainage. Lavender performs best when roots are allowed to dry out between waterings, which helps prevent rot and supports healthy growth.

Riverina Thomas is a high-performing lavandin selected for long stems, strong growth, and excellent essential oil production. It forms a broad, healthy evergreen shrub and produces tapered, true-purple flower spikes that stand upright and harvest cleanly.

Introduced by Clive Larkman of Larkman Nurseries in Australia, this cultivar was bred for oil quality comparable to ‘Grosso’ while offering a long, reliable bloom season. Plants flower generously, often providing multiple harvest windows for oil, fresh cutting, and dried use.

Because of its length and structure, Riverina Thomas is especially well suited for wreaths, bundles, bouquets, and large-scale craft work. It’s a dependable choice for growers who need productivity, uniformity, and strong field performance, and it also holds its own as a bold landscape plant.
