Basil - Dark Opal (Seeds)
Dark Opal Basil seeds yield lush purplish-bronze foliage that make this a truly stunning ornamental plant. It is also known for its herbal uses. This A.A.S. winner has fine flavour and aroma and is excellent for seasoning or use in vinegar. It is not uncommon for a small proportion of the leaves to turn green. One interesting note – basil seeds harvested from mature plants are used as a thickening agent in sweet drinks.
How to Grow
600 seed/gram. Do not rush planting. As Basil loves warm soil and warm temperatures, it will languish if temperatures are below 15 C (60 F). Sow seed directly outdoors in a sunny site with average soil in late May and June. Plant seed 4 mm (3/16″) deep and 6 mm (1/4″) apart. Thin to 20-25 cm (8-10″) apart in the garden. Seed can also be started indoors in a soil-less mix 4-6 weeks before last frost date. Keep temperature at 21 C (70 F) for the 7-10 day germination period, then grow on at the same temperature before hardening off and transplanting outside after the danger of all frost has passed.
