Description

Rising from the bluey-green and bronzed foliage, 'Blue Heron' produces tall, slender stems of aqua blue flowers.

In bloom from May to June, this fabulous perennial will treat your garden to a second flowering around September time. They look great in modern pots and planters yet blend effortlessly into mixed perennial borders and more traditional plantings.

The neat and compact form makes it perfect for growing at the front of beds and borders, as naturally neat edging or covering the empty spaces underneath other plants. Originally a woodland plant, it looks gorgeous dotted through a group of trees too. Very hardy and robust, it will re-appear the following spring bigger and better.

Supplied as a set of three established plants in 9cm pots, ready to pot on or plant out.

Top Tips

Corydalis may go dormant in very dry summers, so keep it well watered.

Care Information

Best grown in humus-rich, moist but well-drained soil in a semi-shaded position, avoiding exposed locations. Will grow well in a sunny border if kept regularly watered to stop it becoming dormant in the summer.
As the plant dies back the leaves will yellow and the stems wither - at this point you can cut them down to ground level, and you may get a second flush.
When new growth emerges in spring, add a slow-release fertiliser to the soil to encourage longer blooming, and continue to feed and wather throught the growing season.
Look out for slugs and snails eating young leaves.
Propagate by division in autumn.
