Basil Red Rubin

What Basil Red Rubin is

Basil Red Rubin (Ocimum basilicum) is an annual herb of the Mint family (Lamiaceae). This is a dark-coloured basil. The dark purple leaves are fresh to use and very tasty.

An ornamental basil that also looks great in the garden. Reaches a height of 45-60 cm.

A strongly aromatic plant with a high content of eugenol and rosmarinic acid.

Its traditional use is against stress, anxiety, heart disease, arthritis, diabetes and dementia.

Basil is the king of aromatic herbs — for tomato salad, pesto, pasta and pizza. It grows easily in the garden, in a pot and on a windowsill.

When to sow Basil Red Rubin

How to sow and grow Basil Red Rubin

• Germination: 5–10 days at 20–25 °C

Sow basil seeds directly in the garden once all danger of frost has passed. For areas with short growing seasons, start the herb seeds indoors 4 - 8 weeks before moving outside. Grow the basil herb in rich, well-drained soil and in the sun. Plant basil in the vegetable garden next to tomatoes and peppers as a companion plant to repel aphids, mites and hornworms on the tomatoes. Basil seeds need warmth to germinate, ideally around 21°C. This can easily be achieved on a sunny windowsill indoors. Basil can also be grown indoors all year round, especially if you have a sunny window or full-spectrum lights. It does great in containers; just make sure you add some compost or another nutrient-rich amendment to your potting mix. Once germinated, encourage strong seedlings by giving them plenty of sun and moisture. Do not overwater: basil seedlings are very prone to damping off. A greenhouse is the ideal place for your basil plants, just make sure you water them often to prevent them from flowering prematurely.

Sow in warm soil — below 12 °C basil stops growing. Pinch out the tips so it branches, and remove flowers for more leaves.

Harvest and use

Pick the leaves before flowering — the aroma is strongest then. Cut above a pair of leaves so that new shoots form.
