By: Bonnie L. Grant, Certified Urban Agriculturist

Basil is one of those herbs that adds a unique, almost licorice scent and outstanding flavor to many international cuisines. It is an easy-to-grow plant but requires warm weather and is frost tender. In most areas it is considered an annual but can be perennial in tropical regions. Superbo basil is a prolific leaf producer and has intense flavor.

What is Superbo basil? Keep reading to find out more about this variety of basil and how you can grow this fragrant herb.

What is Superbo Basil?

There’s basil and then there’s Superbo pesto basil. It is aclassic sweet basil and has a starring role in one of the most popular foodsfrom Italy – pesto. Superbo pesto basil was developed specifically for thatzesty sauce. According to Superbo basil information, it makes a greatsubstitute for Genovese and has a more intense flavor.

Superbo is a compact, bush-like herb. The basic essentialoils in basil, which give it the unique flavor, are cineol, eugenol, linalol,and estragol. These provide the spicy, minty, sweet, fresh taste of the herb.Superbo basil information informs us that it was developed by choosing thebasil species with the highest amounts of the first three oils, leaving out themint flavor.

Pesto is only one of Superbo basil uses, but it was withthis sauce in mind that the variety was developed. The medium plant has deeplygreen leaves that slightly cup under. It was bred from ‘Genovese classic.’

Tips on Growing Superbo Basil

Basil is started from seed. Plant outdoors when soiltemperatures are at least 50 degrees Fahrenheit (10 C.). In order to keep cropsgoing as you harvest, successively plant every three weeks. Make sure the soilis fertile and well draining, and grow the plant in full sun.

In cooler regions, plant indoors in flats 6 weeks before thelast expected frost. Harden off seedlings after they have developed two sets oftrue leaves and plant them in a prepared bed.

Keep basil moderately moist. Harvest leaves as needed. Inhot temperatures, the plant may begin to bolt. Pinch off flowers as they appear.

Superbo Basil Uses

There’s more to food than pesto, although that is a goodstart. Use Superbo fresh in salads, as a garnish on pizza, tossed in pasta andin dressing and marinade.

If you have a bumper crop, make pesto and freeze in ice cubetrays or muffin tins. Dry basil leaves in a food dehydrator and store in aglass jar in a cool, dark place for winter use.

When the plant is getting older, use the leaves to make afragrant and flavorful oil or vinegar. If you take almost all the leaves on aplant, cut the stem near the soil, leaving at least three nice big leaves. Itshould sprout anew and produce more leaves.

Basil may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden, or planted as a potted plant.

Sowing Seed Indoors:

  • Sow basil seeds indoors 6-8 weeks before the last frost in spring using a seed starting kit
  • Sow seeds ¼ inches deep in seed-starting formula
  • Keep the soil moist at 70 degrees F
  • Seedlings emerge in 7-14 days
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • If you are growing in small cells, you may need to transplant the seedlings to 3 or 4 inch pots when seedlings have at least 3 pairs of leaves before transplanting to the garden so they have enough room to develop strong roots.
  • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

Sowing Directly in the Garden:

  • Direct sow in average soil in full sun after all danger of frost when the soil is at least 60 degrees F.
  • Remove weeds and work organic matter into the top 6-8 inches of soil then level and smooth.
  • Sow seeds evenly and cover with ¼ inches of fine soil.
  • Firm the soil lightly and keep evenly moist.
  • Seedlings will emerge in 7-14 days, possibly longer in cooler soils.

Planting in the Garden:

  • Select a location in full sun with good rich moist organic soil.
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Carefully remove the plant from its pot and gently loosen the root ball with your hands to encourage good root development.
  • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
  • Use the plant tag as a location marker.
  • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.


Keep your basil plants healthy

Downy mildew has taken a toll on basil the last few years. (Photo: Provided by Purdue Plant and Pest Diagnostic Lab)

Basil has taken a huge hit over the last few years from a downy mildew, which can quickly decimate a crop in the farmers' fields, growers' greenhouses and our gardens. Downy mildew is the common name for this disease, even though the fungus that causes it may be different, depending on the plant. It gets the name from the symptoms, downy-like fuzz on the leaves.

On basil, the culprit is Peronospora balbahrii. Initially, the leaves turn yellow, and then black spots appear. That's followed by fuzzy spores on the undersides of leaves. The problem starts at the base of the plant and moves up. The fungus is airborne or can be splashed on plants from infested soil. Plants and seeds can be infected, according to the University of Minnesota Extension, where the disease first showed up in 2012.

Here in Indiana, Purdue University has seen only a handful of samples since 2009. "A couple each year," said Tom Creswell, director of Purdue's Plant and Pest Diagnostic Lab.

"Most of our reports from the home garden have been from the home garden of Tom Creswell," he joked. "It seems that if this is showing up extensively in the home garden, then either no one is paying attention or it comes on so late in the season that they've already made pesto, or they don't know they can send samples to the lab for help."

• Remove any infested leaves. It's all right to eat healthy leaves from infested plants.

• Plant resistant varieties. Sweet basil (Ocimum basilicum) is the most susceptible, which includes Genovese, Nufar, Italian Large Leaf, Queenette, Superbo, Poppy Joe's and others, according to Minnesota Extension. Red Rubin and Red Leaf (O. basilicum purpurescens) and lemon basils (O. citriodorum) are considered moderately susceptible. Blue Spice, Spice and Blue Spice F1 (O. americanum) are less susceptible.

• Don't plant basil in the same spot year after year. If you grow basil in a pot, dump the soil each year and scrub the pot with a solution of one part bleach and nine parts water. Use fresh potting mix each year.

• Give plants plenty of air circulation.

• Closely examine basil plants at garden centers to make sure they are symptom free.

• Consider growing basil from seed. It's easy and plants come up quickly.
