Obregonia denegrii, commonly known as “Artichoke Cactus” or “Mexican Old Man Cactus,” is a unique and slow-growing cactus native to Mexico. Growing Obregonia from seed can be a rewarding but patient process. Here’s a guide on how to grow Obregonia from seeds:
1. Gather Supplies:
- Obregonia denegrii seeds
- Well-draining cactus soil mix or a mix of potting soil and perlite
- Small pots or containers with drainage holes
- Plastic wrap or a clear plastic dome
- Grow lights or a sunny location
- Watering can with a fine spray nozzle

- Fill small pots or containers with the cactus soil mix. Make sure the soil is slightly moist but not waterlogged.
- Place the Obregonia seeds on the soil surface, pressing them gently into the soil or covering them with a thin layer of the mix.
3. Watering:
- Water the soil lightly using a fine spray nozzle. Ensure the soil stays consistently moist but not excessively wet.
- Cover the pots or containers with plastic wrap or a clear plastic dome to create a humid environment, which can aid in germination.
4. Germination:
- Place the pots in a warm location with indirect sunlight or use grow lights. Obregonia seeds typically benefit from warm temperatures for germination.
- Germination can take some time, and it may be a few weeks or even longer. Be patient and maintain a stable environment.
5. Light and Temperature:
- Once germinated, provide plenty of light. Obregonia prefers bright, indirect light or filtered sunlight.
- Maintain a temperature range between 70°F to 90°F (21°C to 32°C) for optimal growth.
6. Transplanting:
- When the seedlings are large enough to handle, transplant them into individual pots with well-draining cactus soil.
- Handle the young plants with care, as Obregonia can be delicate.
7. Care and Maintenance:
- Water the Obregonia sparingly, allowing the soil to dry out between waterings.
- Gradually expose the plants to more sunlight, ensuring they receive the proper conditions for cactus growth.
