About plant names...

This cultivar of wormwood is a woody shrub less than 3' (91 cm) high, about 24" (60 cm) wide. It is probably a cross between Artemisia arborescens and A. absinthum.

Identification: Wormwood has sweet-smelling silver-gray fuzzy foliage. Flowers are inconspicuous, yellow, and they appear rarely.

Edibility: Wormwood (specifically Artemisia absinthum) has a bad rap. The fluorescent green anise-flavored spirit absinthe is made from wormwood. An alkaloid from the wormwood, thujone, was reputed to be a madness-inducing, addictive drug, blamed (among many other things) for Vincent Van Gogh’s descent into madness. None of this is true, and this drink, banned in 1915, is once again available in the United States. In any case, the wormwood plant is not considered edible.
