Skill Level: Intermediate
Semiaquilegia ecalcarata, commonly known as Spurless Columbine and sometimes affectionately called “Fairy Bells,” is one of those woodland perennials that puts a smile on my face. Instead of the long, dramatic spurs of true columbines, it offers small, nodding bells held above finely cut foliage—graceful, understated, and capable of sparking a child’s imagination.
This species is native to the mountainous regions of China, where it grows 8-12 tall and 6-10 inches wide along forest margins and lightly shaded slopes. In cultivation, it thrives in partial shade and humus rich, evenly moist soil with good drainage. As with most things in life, what it wants and what it gets might differ, but it doesn’t seem to mind. It is reliably hardy to Zones 5–8, and blooms in late spring, often overlapping with early columbines and woodland ephemerals.
Our Seed Germination Experience
We classify S. ecalcarata as intermediate, owing to its need for a defined cold period to break dormancy. The seeds require two months of cold stratification, after which germination is pleasingly quick—typically within two weeks once exposed to room temperatures.
At Spirithouse Gardens, we sow our seed outdoors or in an unheated Zone 8 greenhouse, waiting for spring germination. This method has been consistently reliable, but the refrigerator method can be used for cold stratification.
Seed viability is the one caveat. Although technically orthodox, S. ecalcarata seed loses viability rapidly, dropping to roughly half after 12 months. Our strongest germination has always come from seed sown within six months of harvest, and we recommend using the freshest seed available.
Plants typically flower in their second year, though we have occasionally seen first year blooms from autumn sown seed that received its cold period in the fridge.
