Lavender Edelweiss is a variety of Lavender intermedia (a hybrid between Lavender angustifolia and L. latifolia). These varieties tend to be taller and stronger than the more compact ‘English’ Lavender plants, they flower later during July and August (and often beyond, well into Autumn) and so are perfect for extending the flowering season and keeping the Summer display going in your garden. The leaves of Intermedia Lavenders tend to be larger and wider, simply because the plants are stronger and taller giving them a good deal of presence in the garden, especially when in flower. Although we have a separate page of the most popular Lavender Hedging plants, Lavender Edelweiss plants are also just as suitable for clipping so there is no reason that you could not use it for this purpose.
Intermedia Lavenders are unsurpassed for their scent, the flowers are borne on long, strong stems making them perfect for cutting and drying, being very prolific with their flowers they are amongst the most commonly used types for commercial pot-pourri and lavender oil production.
Lavender Edelweiss Plants are tough and hardy to at least -15C, just be sure to plant them somewhere sunny and well drained and the plants should take everything that the British weather throws at them in their stride. For best results and to extend the life of your Lavender plants, give them a good trim as soon as the flowers fade (back to the very base of the flower stems, just into the foliage). This will keep them compact and bushy for many years.
