Corydalis ophiocarpa IVORY LARK –
Architectural plant for Deep Shade
Ivory Lark is a vigorous, architectural plant for Shade and Deep Shade. It has a dense filigree of fine fern like, blue-grey-green-bronze foliage, that is really pretty in its own right. In fact this plant is often appreciated more for its wonderful foliage than for its flowers. Long blooming with creamy-lemon flowers.
The creamy-lemon flowers are lovely but are not particularly showy. Though they are long blooming from mid spring to mid summer, with some autumn repeats too, so they decorate the fern like foliage clump for a long time. The creamy lemon blooms with their wine noses certainly look quietly lovely against the unusual shades in the ferny foliage. The whole clump is a neat 45cm. high x 45cm. wide approx. Corydalis ophiocarpa IVORY LARK may be small, but it contributes far above its weight with unusual, evergreen beauty.
Perfect choice for under trees and shrubs.
Corydalis like soils with humus, but well drained, in Full Shade to Part Shade location, as befits their love of growing in woodland locations. They are also perfectly serene in Morning Sun, unless you are in a very hot district. Sadly it is not recommended for districts with high summer air humidity. Will gently self seed where happy, but is not invasive, and is easily pulled out if it puts itself where you don’t want it.
Corydalis ophiocarpa is not a thirsty plant. It is a robust grower with just average, normal garden watering. It can withstand some periods of dry as long as it gets a good water when really needed.
There is little or no ongoing maintenance or work after it is established, and is not known for attacks by any particular pests or diseases.
Robustly frost hardy, even in severe frosts below -10C.
In fact frosts will just bring out foliage colours even more strongly.
Lovely cut for the vase.
Unexpectedly, it is the ferny fronds that make very long lasting indoor vase decorations.
