Verbascum undulatum comes from the Northwest Balkan Peninsula, Albania 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 from seed acquired from Ginny Hunt at Seedhunt but then 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 very interesting plant in 2008. 

The information displayed on this page about Verbascum undulatum is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.
