L. x allardii came from a cross L. latifolia x L. dentata. First description of it is already in 18th century. It can grow very quick. If planted in the garden it can reach a height of 150 cm. If planted in a container it 'll reach a height about 100 cm. Of course the triangular foliage is aromatic...It will not always flower because it puts most of its energy in growing so tall. The flowers are soft blue, inconspicuous, but are elegant placed in long somewhat pointed clusters. Overhere, in my zone 8b, it is not hardy enough for in the garden helas...only in a container. Sometimes this Lavandula is wrongly offered as L. dentata.
