Hyssop (Hyssopus) is an attractive perennial herb native to Europe. This plant is hardy in zones 3 to 9 and can be grown as a border plant or as a compact hedge. Hyssop reaches heights of 2 to 3 feet and boasts jaunty spikes of purple, pink or white flowers in summer. This herb is not fussy at all and can be started from seed successfully, as long as the proper growing conditions are met.
Fill a planting tray two-thirds of the way with good quality potting soil. Sow the seeds liberally, and cover with 1/4 inch of potting soil.
Add enough water to thoroughly moisten the soil, but not enough to cause it to become soggy. Water carefully to avoid pushing the seeds too deeply into the potting mixture. Place the tray in a sunny, warm windowsill.
Continue to water whenever the soil feels dry to the touch. The seedlings should emerge in 14 to 21 days. Transplant the seedlings to the garden once they have developed two to three sets of leaves.
Dig a hole that is 5 inches deep. Gently remove the seedling from the planting tray and place into the hole. Replace the loosened soil and tamp down. Add enough water to moisten the soil well.
Water only when the top inch of soil no longer sticks to your finger.
