Barrel Medic
Medicago truncatula

CALIPH is an aphid-tolerant variety bred from Cyprus. It is early-mid maturing and generally begins flowering 80 days after germination, up to five days earlier than Parabinga.

CALIPH is semi-prostrate in habit, has leaflets with a slight purple fleck on the underside and produces clockwise coiling pods. CALIPH has a boron toxicity tolerance superior to that of all other medic cultivars.

CALIPH is recommended for neutral to alkaline soil types ranging from sandy loams to clays, in the medium to low rainfall zones.
