Agave ovatifolia (whale's tongue agave) is a cold-hardy succulent native to limestone mountains of northeastern Mexico. It germinates readily but is described as slightly more difficult than typical Agave species. Seeds are black, flat, and best sown fresh.

Sowing
What to expect
Tips
Surface-sow and lightly press seeds into moist substrate; cover with fine layer of sand or grit. Maintain humidity with plastic cover for first 2 weeks. Keep substrate moist but not soggy. Provide bright indirect light (some agaves benefit from 24-hour light exposure). Remove plastic cover after 2 weeks once germination begins. Seedlings develop single leaf initially; third leaf indicates mature agave appearance. Use pebbles around seedlings to prevent falling over. Start with 20-20-20 liquid fertilizer at half strength once established. Sow in early spring (55-70°F/13-21°C range)
