Name: Corydalis lutea – aka Yellow Corydalis
Type of Plant: A short-lived perennial with soft, ferny foliage and bright yellow flowers that bloom for most of the summer. Hardy in Zone 5 to 7.
Why I Love/Hate this plant: Yes, it’s short lived, but it’s worth growing! This plant self-seeds and will grow in gravel, cracks in rock walls, or in ordinary garden soil. It thrives in part-sun to full shade where the summers aren’t too hot.
Since the foliage is fine in texture, Corydalis lutea is a perfect contrast to large-leaf Hosta or even Epimedium.
A Word to the Wise: If you like plants that self-sow and travel around a garden, this plant is for you. Get seeds and start a few plants in pots this spring. Once you plant these out, they will gently spread on their own.
