Mentha suaveolens,
a European perennial, escaped during the horticultural process and
grows wild in lowland grasslands. It smells of mint, with the whole
plant abundant in white hairs. The phyllotaxis is the opposite; the
leaves measure 3-5cm long and 2-4cm wide, in the shape of an oblong
or orbicular, with no petioles and the bases embracing the stems,
uneven surfaces with deeply dented veins, serrations on the margins,
and glandular dots on the backside. Branch tops produce 3-6cm long
inflorescences and bear many white, labiate flowers, each with four
stamens, two of which are prolonged and project out of the corollas.
Fruit branches into four mericarps or three occasionally. Bloom
time: July-September. |
