Ocimum basilicum (Basil, Sweet basil)

Datura metel grows 3 to 4 feet tall with large dark green leaves that have a bad smell. However, the large trumpet-shaped flowers have a sweet fragrance that spreads throughout the garden in the morning and evening. Flowers may be single or double and range from white and yellow to pink and purple.

'Pesto Perpetuo' basil not only produces copious amounts of leaves for cooking but also is easy on the eye. It has creamy white variegated leaves and a columnar habit. It does not flower, so nothing will detract from the foliage.

This hardy, fast-growing evergreen shrub has an upright, rounded form and attractive flowers. Shiny green, needlelike leaves are aromatic. It bears small blue flowers in early spring and is loved for its strong, pinelike flavor and fragrance.

Golden oregano is a robust creeper with tiny, rounded leaves 1/2 to 1 inch wide. Small, pink or lavender to purple flowers stand out above the foliage in early to late summer.
