Verbascum undulatum (Wavy-leafed Mullein) - Branching short lived perennial with interesting pinnately lobed leaves that are densely covered with golden yellow hairs. Branching from a basal rosette, 6 to 8 inch long leaves emerge. The flower stems rise unbranched carrying the 1 inch wide yellow flowers. This plant is all about foliage and flowering should not be encouraged - cut off to maintain plant in vegetative state. Plant in full sun and water only occuasionally to infrequently. It is cold hardy to at least 20 degrees F. This plant originated from the Balkan Peninsula and Greece. The name for the genus comes from the original Latin name for the plant which likely comes from the combination of the stem word 'ver' meaning "spring" combined with 'barbascum' meaning "bearded" in reference to the often hairy leaves of the genus. The specific epithet is from the Latin word 'unda' meaning a "wave" or "surge" in reference to the characteristic wavy (undulating) margins of the leaves. We began growing this unusual and attractive plant in 2003 but propagated it from cuttings which was a difficult process as we had to maintain a large number of plants to cut from. We reluctantly decided to stop growing this plant in 2008. 

This information about Verbascum undulatum displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
