PhenologyFlowering and fruiting March-June.
IdentificationCarpet-bugle is an old garden favorite. The plants are perennial from surficial stolons that have pairs of ovate leaves. A central, leafy stem grows erect with a terminal, dense inflorescence, altogether only 4-10 inches tall, with blue or violet flowers. Nothing else looks quite like it, though an inexperienced person might try to turn the very common Ground-ivy (Glechoma reptans) into this species, as they have similar flowers (but not inflorescences).
Taxonomic Comments
Other Common Name(s)Often known as Bugleweed or Blue Bugle(weed), but as the members of the genus Lycopus are generally named as "bugleweed", this exotic species must use a different and non-confusing common name.
