Window boxes are becoming so popular, they are now available as a poster!
But for those of you who are still keen to enjoy the real thing, you can recreate this look with ease.
Simply combine purple petunias, argyranthemum (I like 'Vancouver' or 'Petite Pink' , Lobelia (e.g. Royal Jewels) and the pale silvery foliage of the licquorice plant, Helichrysum petiolare in a white terrazzo planter...
I love the combination of silver, purple and green in a window box. It always looks beautiful.
Alternatively, you may prefer a pink colour scheme
You can recreate this look with lobelia and petunias. The key is to use several different petunias such as 'Pink Lady', Blue Daddy, and Picotee
But I must admit, I'm tempted to throw a double into the mix - such as this stunning Petunia 'Purple Pirouette'
