description
Mentha pulegium is the smallest of the perennial mints in the Lamiaceae
family.
Two varieties are common, the variety decumbens, has weak, prostrate
stems, bluntly quadrangular, 3 inches to a foot long, which readily take
root at the lower joints or nodes. The leaves are opposite, shortly stalked,
more or less hairy on both sides, round/ oval, grayish green, about 1 to 1
1/2 inch long and 1/2 inch broad. The flowers are in whorled clusters of ten
or a dozen, rising in tiers one above the other at the nodes, where the
leaves spring in pairs, beginning about the middle of the stem, their color
reddish purple to lilac blue, and in bloom during July and August. The seed
is light brown, oval and very small.
The other variety, erecta, has much
stouter stems, not rooting at the nodes and not decumbent, but erect or
sub-erect, 8 to 12 inches high. It is rarer, but the best for cultivation,
as it can be reaped and tied up in bundles easily, whereas the stems of
decumbens form a dense green turf. The leaves of either, when crushed, have
a spearmint-like scent.
common names & nomenclature
One of its popular names is pudding grass, from being formerly used in the
stuffing for hog's puddings.
