I love my skullcap, Ive had it in a part sun herb garden for at least four years now and it has grown to 3 around only about a foot high, covered with dark purple orchid like flowers the hummers go from one to the other spending a lot of time making sure they hit every one of them! Im trying some new ones this year, mine doesnt require a lot of water very drought tolerant even with the drought we had last year (2007), I have the hard clay soil and it does very well.

A perennial herb from the mint family with many small blue-purple flowers on woody stems in the second year.
Start seeds indoors in late February or early March at 1/4 inch depth.
Soil temperature should be at 50-60 degrees.
Transplant into garden when seedlings are 4-6 inches tall, and all danger of frost has past.
Plant in full sun, in well drained soil.

Watering: During germination, keep the entire starter-bed evenly moist by misting/spraying.
Keep plant well-watered through maturity, allowing soil surface to dry between waterings.

The Chinese have used this valuable plant as a medicinal herb for over 2,000 years, it is very versatile.
Plants must be 3-4 years of age to be used medicinally.
Harvest mature roots in the spring and dry in partial shade in a well ventiated place. The root matures in the 3rd year.
