 Red Clover.-Although many varieties of Red clovers (Tri-
folium pratense L.) are considered agricultural biennials in other
states they generally behave as winter annuals under Florida
conditions, due to leaf diseases and insect injury. Varieties

 Crimson Clover (Trifolium incarnatum L.), 8 to 30 inches
tall, has very hairy leaflets with whitish markings in the center
and produces long, crimson colored seedheads (Fig. 40).
 The varieties of this clover differ greatly in adaptation, but
none has proved to be satisfactory for peninsular Florida. Pre-
liminary tests indicate that certain strains reseed and make
satisfactory growth in western Florida. Crimson, like other
