Verbena bonariensis is actually not a standard perennial, but a biennial. Because this plant usually self-seeds, you can still enjoy it for years! It spreads like an adventurer among other plants, creating a loose and lively character of the border. Yarrow blooms from July to September and grows about 100-150 cm tall. With its tall, little-leaved stems and airy purple flowers, it can really stand elegantly among other plants. An absolute winner in the garden.
