St Johns Wort is a fantastic herb for medicinal uses. It is great for treating depression naturally. In Germany eight times as many patients take St Johns Wort for mild depression as prozac. It can be used as a tea by drying the leaves and flowers. The red oil from the plant can also be used on wounds, and sunburns to aid healing, and taken internally it can help stomach ulcers. On the downside, it can be very invasive.
St Johns Wort has nice yellow flowers, grows 12-18 inches tall, and is a perennial herb in zones 4-8, but be careful as it can be toxic to livestock, and is considered an invasive species. I would suggest just a couple of plants that you actively manage to keep from getting out of control.
I planted St Johns Wort in my greenhouse in February. It is extremely slow growing when it is starting out, so you really have to be patient. The seed is very small, so I planted the seed just beneath the surface in pots. After three months, they were finally mature enough to go outside. This herb can be transplanted outside as early as 2-3 weeks before your last frost date.
