Verbascum olympicum (Large Plant)

Verbascum longifolium var. pannosum, Olympian Mullein

For almost instant impact in cottage garden borders, look no further than Verbascum olympicum. This imposing perennial will fill a gap in hot dry borders and makes a spectacular focal point, growing to 2 metres in next to no time! The felted, silver rosette of basal foliage plays host to tall spikes of buttery-yellow flowers. Verbascum olympicum is a relatively short lived perennial, which tends to bloom in its third year, and often dies after its spectacular display. However this Mullein is a vigorous self-seeder so you can look forward to plenty of new seedlings popping through the soil to take its place.

This low maintenance perennial is an excellent summer addition to borders, performing best in poor soils where many other plants would struggle to establish. A low maintenance Mullein for cottage gardens and wildlife gardens. Height: 2m (6.6'). Spread: 60m (24").
