Giant hyssop

Agastache rugosa combines aromatic foliage with upright violet-blue flower spikes that appear for many weeks in summer. Its natural growth habit makes it a perfect fit for perennial borders, herb gardens, and naturalistic plantings. Thanks to its abundant nectar supply, this hardy perennial is one of the most popular plants for bees, bumblebees, and butterflies.

Watering and Care

Agastache rugosa performs best in well-drained garden soil that retains some moisture without becoming waterlogged. During extended dry spells, regular watering helps the plant remain healthy and encourages strong flowering. Once established, it becomes more resilient, but consistent care will always result in the most attractive growth.

Maintenance

Remove faded flowers and damaged foliage on a regular basis to keep the plant looking tidy. Cutting back old stems in spring encourages fresh new growth and helps maintain a neat habit.

Location

A position in full sun or light partial shade is ideal. Rich, loose soil with good drainage allows the plant to develop fully and produce abundant blooms.

Tip

Agastache rugosa combines beautifully with other perennials and provides long-lasting colour, texture and seasonal interest in the garden.

Agastache rugosa adds decorative accents to beds and borders with violet flowers. Ideal for sunny, natural-style gardens that attract butterflies and bees.

The plant grows upright and adds vertical dynamism to the bed.
