Clover

FIXatioN is the late‑maturing, cold‑tolerant standout among balansa cultivars, repeatedly out‑surviving and out‑growing Frontier in independent NRCS trials—posting 83–98% winter survival through an Idaho −23°F winter (vs. 52–51% for Frontier) and delivering taller canopies and higher biomass/DM yields across multiple years and sites. (nrcs.usda.gov)

Viper is a late‑flowering, long‑season balansa selected from Bolta for enhanced seed production—delivering strong self‑regeneration and persistence under grazing—and is PBR‑protected in Australia (Pristine Forage Technologies, 2004). (agric.wa.gov.au, dlfseeds.com.au, pir.sa.gov.au)

Dixie is the classic hard‑seeded, reliably reseeding crimson clover—developed by the Georgia Experiment Station as a synthetic of the Allen, Thornton, and Hardy strains—with dependable volunteer stands and very early maturity (about a week earlier than Chief/Talladega) and proven adaptation across the Gulf Coast. (dlg.usg.edu, sarep.ucdavis.edu, gutenberg.org)

Majestik (registered as ‘Majestic’) is a medium-early crimson clover from McCarthy Research Farm selected for seedling vigor and winter hardiness; trials report standout cold tolerance plus fast early canopy (~35% in February) and 100% spring stand/cover with top dry‑matter yield in an Ohio test, with adaptation verified across Ohio, Tennessee, and Mississippi. (aosca.org)

RegalGraze is a UGA-selected Ladino bred under intensive grazing that delivers superior grazing tolerance versus other Ladino types in UGA tests and is acyanogenic (no anti‑quality cyanogenic glucosides). (southeastagriseeds.com, barusa.com)

Barduro (Florida AES release, 2009) is a mid-dormant red clover bred for high resistance to root-knot nematodes and strong Southeastern adaptation—ranking among the top dry-matter yielders in upper Coastal Plain/lower transition-zone trials—and is specifically recommended for South Georgia plantings. (acsess.onlinelibrary.wiley.com, georgiaforages.caes.uga.edu)

Kenland (University of Kentucky, 1947) became the U.S.’s most widely used red clover for its southern adaptation—good resistance to southern anthracnose and comparatively better crown/root‑rot tolerance—providing superior yield and persistence versus common types. (extension.missouri.edu, news.ca.uky.edu)

Medium red clover is the quick‑regrowing, multi‑cut type—typically one cut in the seeding year and two the next—so it delivers more total biomass and nitrogen across seasons than mammoth and provides dependable second‑year groundcover for hay, grazing or seed. (sare.org, canr.msu.edu)

Redkin is an early-flowering, multi-cut diploid red clover with an unusually broad disease package—resistance to northern and southern anthracnose plus downy mildew and black patch—and extreme winterhardiness; notably, stands often strengthen into the second year, unlike many 3‑year multi‑cut types.

White (white‑blossomed sweetclover, Melilotus albus) distinguishes itself by taller, more erect, coarser stems and a bloom that starts about 10–14 days later yet lasts longer than yellow types—extending the pollinator window and providing upright residue—with reports of easier establishment in New York. (sare.org, ag.purdue.edu)

Yellow blooms about two weeks earlier than white types and is smaller, leafier and finer‑stemmed with greater drought tolerance and easier dry‑soil establishment—trading a bit of above‑ground yield for earlier maturity and stress resilience. (extension.umn.edu, sare.org, fs.usda.gov)

Durana, developed at the University of Georgia by Dr. Joe Bouton from stolon‑dense Georgia ecotypes, is distinguished by exceptional persistence under heavy grazing—UGA tall‑fescue trials maintained about 43% clover with Durana by year two while the ladino standard ‘Regal’ dropped below 5%—making it UGA’s recommended white clover where pastures are grazed very short. (extension.uga.edu, acsess.onlinelibrary.wiley.com, fieldreport.caes.uga.edu)

Dutch (intermediate) white clover stays shorter and more prostrate than ladino types, with higher stolon density and profuse flowering that drive natural reseeding and long‑term persistence under heavy grazing—making it the preferred choice for lawns and living‑mulch/inter‑row strips.

Ladino is the large‑leaf, tall white clover type (originating from the Italian Ladino ecotype) that delivers the highest forage yields among white clovers and fits rotational grazing/hay systems, but compared with Dutch/intermediate types it has fewer stolons, reseeds less, and is less persistent under heavy continuous grazing.
