Landscape Use: Low edging, formal hedge to small multiple-trunk tree. A versatile plant with many landscape uses that are mostly cultivar specific. Ergo, know your cultivar differences!

Form & Character: Highly versatile evergreen shrub, low mounding to upright small tree, spreading and pendulous, peeling cinnamon-brown trunk is very attractive. In the Phoenix area common myrtle is an old fashioned, traditional landscape shrub for mesic landscape design motifs.

Growth Habit: Dwarf cultivars grow as low as 3 feet in height. In contrast, the straight species is an upright and large shrub to small tree to 15 feet tall with a greater than equal spread.

Foliage/texture: Medium green, glabrous, simple leaf, lanceolate and sessile to 1 inch long, distinctly aromatic; fine to medium fine texture.

Flowers & fruits: Small, cream-white flowers arising from axillary flower buds followed by small black drupe-like fruit in summer and fall.

Seasonal color: Common myrtle produces a plethora of small, cream-white flowers in April to May.

Temperature: Hardy to 10oF.

Light: Partial to full sun, no shade.

Soil: Iron chlorosis will develop in highly alkaline, wet soil conditions, and I don't recommend use of common myrtle if the soil is above 8.3. Soil must be well drained. If chlorosis occurs because of high soil alkalinity, then regularly treat with elemental sulfur and use NH4+ or urea forms of nitrogen fertilizer to help lower soil pH.

Watering: Common myrtle is surprisingly drought tolerant in Phoenix, but will respond best to regular though not frequent deep waterings.

Pruning: Common myrtle responds well to any type of pruning. Large specimens may be trained into beautiful multiple trunk small trees with amazing cinnamon-colored, twisted trunk patterns; whereas, dwarf cultivars may be sheared with great success by experienced or inexperienced 'horticultural clods' alike into any number of formal shapes.

Propagation: Cutting or seed.

Disease and pests: Rare outbreaks of spider mites during the summer are the only problem this plant ever seems to have in Phoenix.

Additional comments: One of the more serviceable and versatile shrubs in Southwest landscapes for mesic landscape designs. Common myrtle makes a great formal hedge plant (hint, hint for all you people who like landscape boxes, beer kegs and bowling balls). Myrtle is the perfect firewood. Cultivated varieties include:

 The bark and roots are used to tan the finest Turkish and Russian leather to which it imparts a delicate scent. Common myrtle has a notable Biblical tradition.

Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree. - Isaiah 55:13
