I planted the seeds on 3/13/11 & already had seedlings popping up on 3/19/11. The thing is - I can't find any info on the way the seedlings actually emerge & grow. It seems as though they shoot up & then they seem to 'fall' over & start burrowing into the soil. I saw quite a few of them right on top of the soil - including the seed - & I tried to plant the seed again - but noticed the others trying to burrow back into the soil.

A shrubby perennial from the Mediterranean, South West Asia and China.

Has pinnate (upto 20 ovate leaflets), sticky, mid green, leaves. Bears bluish or pale purple and white, pea shaped flowers.

Flowers August-September

Likes a moist, fertile soil in full sun. The tap roots can grow very long (4ft) and prefer a deep soil.

Liquorice is made from the woody rootstock of this plant, which has been used in confectionary, making of porter and to sweeten tobacco.

Liquorice was also used medicinally, certainly since ancient Greek times. It has been used in eye problems, cough medicine, treatment of sore throats and as a laxative.
