Gardeners' Notes:

Positive cranberryfiend On Dec 22, 2014, cranberryfiend from Stamford, CT wrote:

Have grown--well, it grows itself--this basil for 10+ years; it self-seeds nicely. Called it "sweet-smelling basil" before learning it's true name; came in a "Basket of Basils" packet from an English seed company. Flavor has slight anise overtones, makes great pesto and great for every other basil use. Never gets bitter, even when flowering. Saw-toothed leaves can get up to 3" long and 2" wide; whole plant is bush shaped, can be 2+ feet tall. Bees and beneficials LOVE the 4-8" tall flower stalks, they could be saved for sachets with their lovely scent. Seeds that land in outdoor plant pots will grow when the plants are brought in for the winter for basil all year long. Also dries well. Fairly drought tolerant--just droops--perks right back with rain; gets no additional water from me here in CT

Sow seeds on the surface of a Well drained seed sowing mix at about 59 to 70F, germination is 15 to 30 days.

Heating pad helps germination.

It is said to have a spicy fragrance with a vanilla overtone.

It can be used in fruit salads, with poultry and probably in many other dishes where you would use sweet basil.

Said to be a hybrid between purple basil and O. americanum.
