Blue Flowering Shrubs

Blue Themed Garden?
Whether you’re tempted to create a blue colour themed garden, or wish to provide continuity of colour through the seasons, choosing plants and shrubs by colour alone is sometimes a necessary requirement.  The coolness of blue flowering shrubs can be a foil, for hot contrasting colours such as yellow or orange, or will create an elegant understated design, when used with white and silver leaved plants and shrubs. Here, we’ve chosen some of our absolute favourite blue flowering shrubs, for their depth of colour and fragrance and it’s therefore no co-incidence that these shrubs will attract many pollinators into your garden.

Shrubs For Wildlife
At Paramount Plants we view it as an absolute necessity to help our wildlife wherever possible, to provide them with the sustenance they need to thrive in our gardens whether in the countryside or in an urban setting. Many of our blue flowering shrubs are also found in our Shrubs For Wildlife section.
Blue Flowers – A Rarity
Blue flowers have historically (because of their relative rarity) been given special status in garden designs, here we’re suggesting a range of perennials, evergreen shubs and climbers that can be used to create the most sumptuous blue gardens or selectively chosen to complement your current garden scheme.
Agapanthus – African Lily
The tall imposing flowerheads of Agapanthus or African lily (despite their origins from South Africa), absolute thrive here in the UK. We have both blue and white varieties of Agapanthus Africanus and Agapanthus Africanus Albus plus the slightly smaller Agapanthus Blue Storm these perennials are particularly beautiful when planted en masse in a bed or border. They will also work very well in pots on the terrace.

Rosemary
These evergreen shrubs are known for their herbal and culinary uses but we would like to introduce the concept of using Rosemary as a low growing hedge. These evergreen shrubs can be planted in the border, as a low-growing boundary hedge to soften a building or as part of a three tiered hedging design. Rosemary is easy to keep trimmed to shape and will reward you with beautiful blue flowers that are loved by bees and all pollinators.
