Teucrium ( germander) is a genus with some very different looking species.  Teucrium cossonii majoricum is a low growing groundcover with grey foliage and whorls of mauvey purple flowers that smell like honey.  T. x lucidrys (formerly T. chamaedrys) has dark green, toothed leaves with pink flowers.  It grows to about one by two feet.  T. fruticans is a shrub that can reach eight feet and has silvery leaves and lavender flowers.  ‘Azureum’ has darker, more violet flowers.  All will tolerate poor soil and need only moderate water.

Myrtus communis

Myrtus communis, or myrtle, is a dense shrub that does well in full sun or partial shade.  Leaves are small, bright green and aromatic.  White, fragrant flowers appear in summer.  It generally grows to about six feet (or more with age), but ‘Compacta’ stays about three by three feet.  Good drainage is essential.

Rhaphiolepis

Rhaphiolepis indica, or Indian hawthorn, is a very useful, fairly low-growing shrub to about five feet.  Flowers are white or pink.  R. umbellata has very dark green leaves and white flowers

Laurus nobilis

Laurus nobilis, or sweet bay, is the bay leaf used in cooking.  It is a handsome evergreen shrub that grows anywhere from twelve to forty feet, but in our climate, usually stays in the twelve to fifteen foot range.  Yellow flowers appear in spring.  It  can take full sun or partial shade and needs moderate water.  Good drainage is essential.

Euonymus microphyllus

Euonymus j. microphyllus, or box-leaf euonymus, is a slow growing evergreen shrub that grows to only one to two feet tall and about half as wide.  It is frequently used as a hedging plant.  It prefers full sun and moderate to regular water.

Cotoneaster

The Cotoneasters listed here are all evergreen and require little to moderate water.  They have small white flowers in spring and red berries in autumn and winter.  The most common groundcover types are ‘Coral Beauty’, ‘Lowfast’ and ‘Streib’s Findling’, all of which will get about ten feet wide and do well in sun or partial shade.  C. lacteus is a graceful shrub with arching branches that grows to eight feet or more, also with white flowers and red berries.  Leaves are dark green on top and almost white underneath.  It prefers full sun.
