[James Kilkelly, was GPI.]

A shrub or bush is a horticultural rather than strictly botanical category of woody plant, distinguished from a tree by its multiple stems and lower height, usually less than 6 m tall.
A large number of plants can be either shrubs or trees, depending on the growing conditions they experience.
Small, low shrubs such as lavender, periwinkle and thyme are often termed subshrubs.

A natural plant community dominated by shrubs is called a shrubland.
The word bush can also refer to a type of plant community, as in the Australian bush.
This is often characterised by scrubby, open woodland and is a generic term for Eucalyptus dominated woodland in particular.

An area of cultivated shrubs in a park or garden is known as a shrubbery. When clipped as topiary, shrubs generally have dense foliage and many small leafy branches growing close together.
Many shrubs respond well to renewal pruning, in which hard cutting back to a 'stool' results in long new stems known as "canes".
Other shrubs respond better to selective pruning to reveal their structure and character.

Shrubs in common garden practice are generally broad-leaved plants, though some smaller conifers such as Mountain Pine and Common Juniper are also shrubby in structure.
Shrubs can be either deciduous (sheds and renews leaves annually) or evergreen.

Does anyone have a crape myrtle and would you recommend planting from seed? I've been on ebay and saw some seeds for the plant which flowers very well and seems hardy in zone 6. Though prone to mildew, sea breezes should negate that unsightly feature. I don't care about the dropping florets as that adds to compost and soil enrichment. My question is, do people like the plant or not? I don't think it is over common in the area, is it over blowsy and too dramatic as a landscape feature? I'm going for a Mediterranean look in parts with mauves and pinks - any comments on this plant?
