 Common Name: Mullein

With a goal of breeding new hybrids with larger flowers in new colors on plants with a longer lifespan, the National Collection holders of Verbascum, Vic Johnstone and Claire Wilson, used various wild Verbascum species to develop more than 1000 hybrids.  Out of this large number of seedlings, the best dozen were selected and named The Riverside Hybrids.  ‘Clementine’ is one of the twelve. 

This plant was first introduced at the Hampton Court Flower Show in 2003.  It is a beautiful architectural specimen and the tallest of all Verbascums we offer.  Well-branched stems carry tall spikes of peachy apricot to brighter orange flowers with fuzzy violet purple filament hairs in the center.  Deadheading spent blooms tends to prolong the bloom time.  ‘Clementine’ is said to be more reliably perennial than many other Verbascums.

Homeowner Growing & Maintenance Tips:

Verbascum demands light, well-drained soil. Wet soil often leads to its demise. Full sun is also required. When properly sited, Verbascum is very low maintenance and easy to grow. It will bloom well into summer if spent flower stalks are removed.

Verbascums are native to Mediterranean areas where rainfall is scarce in the summertime.  Therefore, they are drought tolerant and require little supplemental water except in very hot zones.

While every effort has been made to describe this plant accurately, please keep in mind that the height, bloom time, and color may differ in various climates throughout the country. The description of this plant was written based on our experience growing it in Michigan (USDA hardiness zone 5) and on numerous outside resources.
