Alecost (Tanacetum balsamita) Herb in 9cm Pot

Alecost , Costmary or Tanacetum balsamita, is a decorative and pungent hardy-perennial that was once important medicinally and would have features in every cottage garden but is now seldom used. Alecost can grow to a height of  60-90 cm in dry sunny site. Alecost has Grey-green leaves with a strong mint and balsam scent and is mat forming. Flourishes in a medium soil in a sunny position. Alecost has clusters of white flowers with bright yellow centres in late summer which are attractive to bees and butterflies as it is a good source of nectar, so is a welcome addition in the herbaceous border as well as the herb garden. 

Herb Usage 

Alecost as the name suggests was sometimes used instead of hops in beer- making and you could still use as a substitute. young leaves can be chopped and used in salads but beware it is a pungent taste. Alecost was used medicinally to relieve catarrh. Can also be used in Pot pourri.

Warning: Alecost should not be eaten any time during pregnancy
