This is not just an urban phenomenon.  Even suburban and rural areas can
have landscaped areas with bushes and plants.  It is common, for example,
for small dividing areas between sections of a parking lot at a shopping
center to have bits of bushes, shrubbery or other plants for
aesthetic/decorative reasons.
