description
The broad-leaved lavender is an aromatic, white tomentose, evergreen shrub that reaches heights of up to 80 centimeters. The opposite leaves are elongated to narrowly elliptical, 2 to 5 centimeters long and 2 to 9 millimeters wide. They are slightly rolled up at the edge, short and densely white when young, later gray-green and less tomentose.
Seven to eight pseudo whorls are arranged in 8 to 25 centimeters long, often shorter, more or less loose and very long-stalked (stem 17 to 30 cm) year old inflorescences . Six to ten flowers are grouped together in the dummy whorls. The linear, one-nerved and gray-green bracts have a length of up to 8 millimeters. The flower stalk is very short. The bracts are subpulate and 2 to 3 millimeters long. The hermaphrodite flowers are zygomorphic . The calyx is briefly gray-tomentose, about 5 to 6 mm long, more or less cylindrical and briefly five-toothed, the upper tooth has an inverted heart-shaped appendage. The purple-colored crown is 1 to 1.1 cm long, five-lobed, very indistinctly two-lipped and tomentose on the outside. There are four stamens , two of which are shorter and do not protrude.
The flowering period extends from June to September.
