In Indonesia it's also called kara legi, kratok, kekara or kacang jawa.
It's look like lima bean or butter bean.
But I'm not sure that they are same beans.
As a member of the legume family, kara have a capability of "fixing" their own nitrogen from the air.
So... they do not need nitrogen fertilizer.
Adding nitrogen to the soil will likely result in more vegetative growth and fewer bean pods.
|a bunches of flowers|
Kara (Phaseolus lunatus) are twining vines or herbaceous bushes, perennial in nature, but usually grown as annuals.
It can climb more than 4 m up a trellis or bean teepee.
The leaves have three leaflets, each 5-13 cm long.
The flowers are white to yellowish and quite small, usually less than 2.5 cm in length.
The pods can be 5-15 cm long and 2-3 cm wide.
Kara will grow well at full sun area but adaptable on part shady area.
This plant also able to grow on the barren land.
But need a fairy moist soil for their best growth.
|Bunches of pods|
In central Java, It is commonly known as vegetables that grown for that pods and seeds.
Young pods are cooked and eaten as vegetables.
In Central Java, the young leaves also cooked as a greens.
Old leaves are used as fodder, food coloring, dye and home remedy for stomach ache.
Green color is obtained from the squeezed leaves.
Seeds from old pods sometimes poisonous if eaten raw.
It needs to be cooked, to eliminate the poison.
Kara, like many other legumes, are a good source of dietary fiber, and a virtually fat-free source of high quality protein.
Kara contain both soluble fiber, which helps regulate blood sugar levels and lowers cholesterol, and insoluble fiber, which aids in the prevention of constipation, and digestive disorders
The high fiber content in Kara beans prevents blood sugar levels.
Soluble fiber make the cholesterol level is lowered.
They may help to prevent heart disease.
Kara beans also provide iron, folate and magnesium.
Kara beans are a very good source of the mineral manganese, and help enzymes for energy production and antioxidant defense.
So this is a really useful plant...
Actually I got the seed by way of exchange with my neighbor.
The cheaper way to get various seeds.
