Habit is more open and lax when the species gets much beyond that height. Flower color is pink with yellow tips and by far the most attractive of the two so far described. C. lutea , the European yellow corydalis, is probably the most popular and well known. Corydalis lutea is very close to evergreen in this area. Reaching about a foot in height, it is bushy and dense with small leaves.
Foliage is green on the upper surface, bluish-green underneath.
Flowers are held in small dense clusters of golden yellow. It begins blooming early in the season and continues blooming until around October. I consider it a workhorse for the garden. Corydalis solida C. bulbosa is really C. solida , bulbosa being a rejected synonym for solida . Most catalogs list this plant as solida .
