About
Agastache urticifolia is a robust perennial that can reach heights of up to 2 meters. Its stems are square in cross-section and support pairs of aromatic, lanceolate to triangular leaves that exhibit a glossy texture and have coarsely serrated margins. From mid to late summer, this plant bears compact spikes adorned with small flowers that can appear in shades of pale pink, violet, or white.
About the genus
