The Story
Plant Bio
Agave asperrima is a succulent perennial with rosettes of thick, spiny-edged leaves that form a compact, architectural mound. It produces tall flower stalks with yellow-green flowers when in bloom.
This species is notable for its particularly spiny margins and robust, drought-tolerant nature, making it an excellent choice for xeriscaping and low-maintenance gardens.

Common Questions
Rough Agave questions
What zones can Rough Agave grow in?
Rough Agave is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Rough Agave deer resistant?
Not reliably. Deer may browse Rough Agave, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Rough Agave bloom?
Rough Agave typically blooms in late summer through late fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Rough Agave need full sun?
Rough Agave does best in full sun (6+ hours).
Is Rough Agave drought tolerant?
Yes — once established (usually after the first full season), Rough Agave handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
