Corydalis Blue Heron is a plant that we at YouGarden hadn’t even discovered until 2 or 3 years ago and to say it’s an absolute gem is an understatement. It is simply so brilliant that now we cannot imagine not stocking it!
And we love it for so many different reasons. The plant features wonderful iridescent blue flowers that add a pop of colour to any bed or border. These Tubular shaped flowers have white throats that serve to emphasis it’s electric blue hues. Their gorgeous red stems sit behind providing further contrast. The lovely Glaucous coating on the green foliage add textural interest to the plant.

So you’ll see this at various stands almost every year at Chelsea! And no wonder, as the end of may is when these plants really start to shine, blooming in abundance.
Corydalis Blue Heron is a real winter hardy Gem too. Being a perennial plant, it will survive the winter and it’s flowers will return year on year. Best to plant in a shady spot, these plants will establish quickly and require minimal maintenance.
