Mentha suaveolens,
a European perennial, escaped during cultivation and now 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, occasionally into three. Bloom
time: July-September. |
