In May 2005 Sandrine was preparing H. 'Caramel' plants for an exhibition at Courson in France, when she noticed that one of them was completely yellow, but with the same dense habit and vigorous growth.

She and Thierry immediately seperated it from the batch and ran to the telephone to call Luc Klinkhammer, the trader who'd spotted the potential in H. 'Caramel' and launched it to the world. Bizarrely, Luc replied that a similar discovery had been made almost simultaniously at a production laboratory in The Netherlands, where a newly propagated H. 'Caramel' had emerged in yellow. Truly a case of lightning striking twice!  

H. 'Citronelle' gleams brightly next to its stablemates H. ''Mocha', H. 'Caramel' and H. 'Brownies', as proudly shown off by Thierry.

Once again, a strong-growing Heuchera with bright citrus foliage was a plant in the right place at the right time, so the new variety was rushed into production to be unleashed on the world in 2007 as H. 'Citronelle'.
