How to Start It
★ Recommended for beginners
Columbine seeds need a cold spell before they sprout, so sow them outdoors in late fall, or in early spring about 4 weeks before your last frost, and winter does the work. Press the seeds onto the soil surface without covering them, since they need light to sprout. They come up slowly, often over several weeks, and the plants usually flower in their second spring.
Each columbine plant only lives about 2 to 3 years, but it drops so much seed that new plants keep coming up around it, so a patch lasts for good. Columbines cross easily with each other, so the seedlings often surprise you with new colours.
When To Start
Columbine likes cool weather. Sow it in early spring, as soon as the ground can be worked.

Sow columbine seeds outdoors now, on top of the soil
30 days before your last frost· every year
Optional: plant a young columbine in sun or part shade
Around your last frost· every year· optional
Snip off faded columbine flowers, leave a few for seed
45 days after your last frost· every year· optional
Cut columbine back to fresh leaves after it flowers
75 days after your last frost· every year· optional
Water your new columbine plants well while they settle in. Deep and slow is best.
About 1 days after you plant it
How is your columbine coming along? Keep the soil lightly moist, as the seeds can be slow to wake up.
About 30 days after you plant it
Columbine check! Pull weeds from around the young plants so they do not get crowded.

Planting & Sprouting
Growing Tips
- 1Grow columbine in sun or part shade, with some afternoon shade where summers are hot.
- 2It is happy in most soils that drain well, with a little compost mixed in.
- 3Water during dry spells so the soil does not bake dry, especially in the first year.
- 4It needs little feeding, and a thin layer of compost in spring is plenty.
- 5Leaf miners (tiny grubs) leave pale, wavy trails in the leaves, so cut off those leaves and fresh ones will grow.
- 6All parts of columbine, especially the seeds and roots, are poisonous if eaten, so keep children and pets from chewing them.

Harvesting
When to Pick
Blooms late spring to early summer; leave some seed heads to self-sow
How to Harvest
- 1Cut columbine for a vase when the flowers have just opened, and put the stems straight into water.
- 2Snip off faded flowers to keep the plant tidy and flowering longer.
- 3Leave a few flower heads to ripen and drop their seeds, so new plants replace the old ones.
- 4Once flowering is over, cut the whole plant down to the fresh leaves at its base, and a neat new clump of leaves soon grows.
- 5Pull out tired old plants after 2 to 3 years and let the young seedlings take their place.
Step 5
Saving Seeds
How to Save Seeds
Columbines cross easily with each other, so seeds from a garden with several colours will give new mixes, and named varieties will not grow true. Leave a few faded flowers on the plant until the pods turn brown and dry and start to open at the top. Snip them into a paper bag and shake out the shiny black seeds. Store them labelled somewhere cool, dark and dry, where they keep about 2 years, and remember they need a cold spell before they sprout.
