Annuals are great for filling gaps; they are longer blooming than perennials and help to bridge the gap between perennial bloom times. Many popular annuals come in white forms and some are suited to shade and some for sun. I love the reliability of impatiens and the gracefulness of comos. New plants are on the market every year, but I always turn to those two classics.
Foxgloves are biennials. They grow foliage in their first year and bloom the second. They self sow prolifically and so you can have them in bloom every year once you get a good crop going.
Poppies are one of my favourite flowers and although they are often portrayed in red, they come in beautful oranges, pinks and even white.
Phlox is prone to mildew but the white variety named David is mildew resistant and stunning.
Later in the summer and into early autumn one of my very favourite white flowers comes into bloom. The Japanese Anemone ‘Honorine Jobert’ is beautiful and less likely to spread rampantly as some anemones do.
There are plenty more white flowers available to love. I have listed the ones I can’t live without. But it doesn’t end there. Companions are necessary. A few touches of blue or purple helps to accentuate the white, or at least this is how I excuse my love of purple flowers. You’ve already seen me sneak in the irises. I will have to add some purple petunias as well as white ones, not only because I love them, but in this case it is the purple ones that have a sweet fragrance.
White makes an appearance in foliage too and variegated plants are among my favourites. Hostas make beautiful companions for more delicately shaped flowers and there are many variegated ones to chose from. ‘Fire and Ice’ shown below is just one.
This hosta shows how well green shows off white so using greens to show off the white flowers is like adding greenery to a bouquet. Hostas work well for this as do ferns, conifers and the foliage of rhododendrons. Hosta sieboldiana elegans has blue green foliage which also looks beautiful with whites.
I recently found this blog while looking at pictures of white gardens and this picture, featured on the blog, is a great example of how different shapes and textures of foliage make the garden more visually interesting and how the white flowers really stand out against the green.
