Ancient times brought fame to the St. Johnswort plants because of the discovery of a fluorescent red pigment, named hypericin, that oozes from the crushed flowers. Today, this herb has become well-known as a treatment for many ailments, from sore joints to moodiness. We do not advocate it medicinally, of course, but we find that even if you begin growing St. Johnswort for homeopathic purposes, you may just find yourself falling in love with its ornamental beauty, too!

This shrubby perennial (often grown as an annual because it is relatively short-lived) grows upright to 2 feet tall and about 1½ feet wide, with woody reddish-brown stems. The tiny oval green leaves dot the stems at ½- to 1-inch intervals. Bright yellow blooms, about ¾-inch wide and 5-petaled, appear in summer. St. Johnswort is often grown as a groundcover or a foreground planting in the annual bed and perennial border as well as the herb garden. It thrives in full sun in cooler, short-summer cliamtes and in partial shade farther south and west.

St. Johnswort seed is easy to germinate, but it is not quick, and the sprouting time varies greatly. Start seeds indoors about 10 weeks before the last scheduled spring frost, at a temperature of 50 to 55 degrees F (a chilly garage or basement works well); they should sprout within a month, but may take a bit longer. Once the seedlings are up, they can be transplanted as soon as they have at lesat two sets of true leaves. If you are growing them for harvest, take the top few inches off the plant when it begins to bud in early to midsummer. Pkt is 100 seeds.

Superior Germination Through Superior Science

Park's Superior Seeds Park Seed's humidity- and temperature-controlled seed storage vault Park Seed offers some of the highest-quality vegetable and flower seeds available in the industry, and there are a number of reasons for this.

First of all, we have humidity- and temperature-controlled storage, and we never treat any of our seeds with chemicals or pesticides. Nor do we ever sell GMO's (genetically modified seeds), so you always know the products you're buying from us are natural as well as safe for you and the environment.

Superior Standards - University Inspected

Testing seeds against minimum germination standards To make sure we are providing the best seed product possible and that our customers will get the highest number of seedlings from every packet, we conduct our own germination testing and have quality-control measures in every stage of our seed-handling operation. We hold ourselves to standards that are at or above federal and state standards, including testing specific crops more frequently than recommended by federal guidelines. And in order to maintain our organic certification, we welcome Clemson University to inspect us annually to make sure our organic seeds, which are stored and processed separately, are being handled properly.

Hand Packed By Experienced Technicians

Park Seed has been handling and packing vegetable and flower seeds for 145 years, a history that has given us a great understanding of how each variety should be cared for and maintained throughout every step of theprocess, from collection to shipping.

When packing our seeds, the majority are actually done by hand (with extreme care!), and we often over-pack them, so you're receiving more than the stated quantity.

Some of the small seeds are also offered as "pellets" (have a clay coating) to make sowing and growing easier.
