The hybrid lungworts vary in their origin.  Some are the result of crossing two species and some are from chance seedlings.  These hybrids are the dominant lungworts found in commerce today.  Like other species of Pulmonaria, these hybrids are clumping perennials that are often planted in groups to form a ground cover.

Size and Method of spreading:

Hybrid lungworts will vary in their size depending on the cultivar. In general most of these are under 2 feet in height. They are often used as a clump-forming ground cover. Ground covers are plants that are not usually thought of as ground covers. They are perennials that can be planted closely together to provide the visual effect of a ground cover.
