Agave salmiana seeds can take approximately 1–3 months to germinate under suitable conditions. Seedlings develop slowly, and several years may be needed before the plant forms a large, impressive rosette.
Mature Agave salmiana can reach approximately 8–13 feet in height and width under favorable growing conditions. Its large spreading rosette requires plenty of outdoor space.
Young Agave salmiana plants can grow in large containers when provided with bright light and excellent drainage. However, this species becomes very large as it matures, so spacious outdoor planting is generally more suitable for established plants.
