At least twenty varieties, native or naturalized, are
found in Great Britain; more than twelve varieties belong to the United
States. The more valuable varieties found in this country have been
introduced from Europe, unless it be the small white clover (Trifolium
repens). Viewed
from the standpoint of the agriculturist the varieties
that are most generally useful include medium red clover (Trifolium
pratense), alfalfa (Medicago sativa), alsike (Trifolium hybridum),
mammoth (Trifolium magnum), crimson (Trifolium incarnatum) and small
white (Trifolium repens). The varieties which flourish only in the
South include the Japan (Lespedeza striata) and the burr clover
(Medicago denticulata). Sweet clover (Melilotus alba), sometimes
called Bokhara, which will grow equally well North and South, is worthy
of attention because of its power to grow under hard conditions, in
order to provide honey for bees and to renovate soils. Other varieties
may render some service to agriculture, but their value will not compare
with that of the varieties named.
The most valuable of the varieties named in providing pasture, include
the medium red, the mammoth, the alsike and the small white. The most
valuable in providing hay are the medium red, alfalfa and alsike. The
most valuable, viewed from the standpoint only of soil renovation, are
the medium red, mammoth, alsike, crimson, Japan and sweet. The most
valuable in producing honey accessible to tame bees, are the small
white, alsike and sweet.
