Dark Opal Basil is a type of basil plant that is known for its striking dark purple leaves. It is a member of the Ocimum basilicum species, which is the most commonly cultivated and well-known species of basil.

Dark Opal Basil is an annual plant that is commonly grown for its ornamental value as well as its culinary uses. Its leaves have a sweet, spicy flavor and can be used in a variety of dishes, including salads, soups, and sauces.

Like other basil plants, Dark Opal Basil thrives in warm weather and full sun. It requires well-draining soil and regular watering to grow and produce healthy foliage. It can be grown in the garden, in containers, or even indoors as a houseplant.

How to Grow Dark Opal Basil from Seed?

To grow Dark Opal Basil from seed, follow these steps:

  1. Start by selecting a good quality seed starting mix. It should be sterile and have good drainage.
  2. Fill your seed starting trays with the seed starting mix, and water it thoroughly before planting your seeds.
  3. Sow your Dark Opal Basil seeds on the surface of the seed starting mix, spacing them about 1 inch apart.
  4. Cover the seeds with a thin layer of the seed starting mix, and then mist the surface lightly with water.
  5. Place the seed tray in a warm, bright location, such as near a sunny window or under grow lights.
  6. Keep the soil moist but not overly wet, and avoid letting it dry out completely.
  7. Once the seedlings have reached a height of 2-3 inches, you can transplant them into larger containers or into the garden. If transplanting into the garden, be sure to wait until all danger of frost has passed and the soil has warmed up.

How to Propagate Dark Opal Basil?

  1. Begin by selecting a healthy, mature Dark Opal Basil plant to take cuttings from. Look for a stem that is at least 4 inches long and has at least two sets of leaves.
  2. Use a sharp, clean pair of scissors or pruning shears to cut the stem just below a set of leaves. Make the cut at a 45-degree angle to maximize the surface area for rooting.
  3. Remove the lower leaves from the stem, leaving only the top 2-3 sets of leaves.
  4. Dip the cut end of the stem into rooting hormone, which can help speed up the rooting process.
  5. Insert the stem into a container filled with moistened potting soil or water. If using soil, make a hole in the soil first to avoid damaging the stem.
  6. Cover the container with a plastic bag to create a mini greenhouse and keep the soil moist. Place it in a bright, warm location but out of direct sunlight.
  7. After a few weeks, check the stem for root development by gently tugging on it. If you feel resistance, the roots have developed.
  8. Once the roots have developed, you can transplant the cutting into a larger container or directly into the garden.

How to Harvest Dark Opal Basil?

To harvest Dark Opal Basil, follow these steps:

  1. Wait until the plant has grown to a height of at least 6-8 inches and has produced enough foliage for harvesting.
  2. Choose a stem to harvest, and using a pair of clean, sharp scissors or pruning shears, cut the stem just above a set of leaves. Make the cut at a 45-degree angle to minimize damage to the plant.
  3. If you are harvesting large amounts of basil, it is best to cut the stems in the morning when the plant is at its freshest.
  4. Once you have harvested the stems, you can remove the leaves from the stems by gently pinching them off with your fingers. Be sure to handle the leaves gently to avoid bruising or damaging them.
  5. To store the harvested basil, place the leaves in a resealable plastic bag or an airtight container, and store them in the refrigerator. Alternatively, you can freeze the basil by placing the leaves in a single layer on a baking sheet and freezing them for several hours before transferring them to a freezer-safe container.

How to Grow Dark Opal Basil in Containers?

  1. Choose a container that is at least 6-8 inches deep and has drainage holes at the bottom to allow excess water to escape.
  2. Fill the container with well-draining potting soil. You can also mix in some compost or other organic matter to provide nutrients to the plant.
  3. Plant the Dark Opal Basil seeds or seedlings about 6-8 inches apart in the container. If planting multiple plants, make sure to space them out evenly.
  4. Water the plants immediately after planting and ensure that the soil stays consistently moist, but not waterlogged.
  5. Place the container in a sunny location that receives at least 6 hours of direct sunlight per day. Dark Opal Basil prefers warm temperatures, so it is best to place the container in a warm location such as a south-facing window or a sheltered patio.
  6. Fertilize the plants with a balanced, water-soluble fertilizer every 4-6 weeks. Follow the package instructions for application rates.
  7. Monitor the plants for pests and diseases, and treat as needed.
