Soybean is an annual agricultural crop that produces clusters of small white or purple flowers followed by edible bean pods. This fast-growing plant has the typical three-leaflet pattern of legumes and can reach up to 5 feet tall in optimal conditions.

In an HOA neighborhood

Soya takes more care to keep looking intentional in a front yard. Maintenance level: moderate. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.
