Broadleaves
Buckwheat (Mancan)
Buckwheat is a fast establishing broadleaf that works great as a warm season cover crop. Buckwheat is also known for being a phosphorus scavenger. Which means it can take up more phosphorus efficiently than other plants. Being a short season plant around 45-60 days, it can still produce viable seed throughout the growing season. In a situation where the one plant is grazed it can drop a seed down to take that previous plant's spot to help prevent weeds. This plant while dropping and producing these seeds can also flower making it a great species for pollinators.

Flax (Brown)
Flax can be utilized in many small grain and corn rotations as a potential cover crop or fiber/oil crop. Compared to other common crops, overall nutrient demand is lower and very little nitrogen is needed. Vegetative growth normally requires 50 days before flowering occurs but after this flowering can last 2-4 weeks. Flax can be utilized as a green manure if terminated early enough but take caution if attempting to cut too late as lignin/cellulose content increase with maturity and would hamper decomposition. Nearly 95% of the water flax extracts from the soil is in the top 2-3 feet because of its shallow root structure. Water use is considered moderate with respect to other field crops, but flax uses about 3-4 inches less than soybeans. This is primarily due to the fact that the leaves of flax are generally numerous but leaf area is limited and thus ET is lower. As mentioned before, this species is an excellent companion crop next to other species in an early season mixture. Flax is generally a self-pollinated crop but pollinating insects are attracted to the various blue/purple colors of the flowers. Because flax is a broadleaf species, most diseases associated with it will not transfer over and cause infection to corn, soybeans, or wheat with the exception of powdery mildew and rhizoctonia after legumes.

Sesame
Sesame is a warm season broadleaf that is normally grown for the oil content of the seed. It is one of the oldest cultivated plants and has been grown by people for over 4,000 years. Sesame loves hot weather and can grow with very limited water as well as being fairly tolerant of low pH soils. Sesame can grow 5-6 tall and will put on bell-shaped, white and purple flowers late in the season which makes it a great addition to a full season pollinator mix. Sesame has little to no forage value as livestock will not graze it, but it can still be a good addition to a grazing mix so there is some taller standing structure after the cattle have grazed the paddock.
