Corn Cockle (Agrostemma githago)
Seed grown by us here in the Hunter Valley, NSW.
Description:
An elegant, airy cut flower for early-season production.
Fantastic for wedding/event floristry.
3-5cm blooms grow in sprays on willowy grey stems.
Cold hardy annual so prefers cool growing conditions.
Seed count: 50+
Site: full sun
Height: 80-100cm
Sowing method: Sow in Autumn, Winter (only in temperate/sub-tropical areas) and early-Spring. Frost hardy. Prefers to be direct sown but transplanting also works - try to avoid too much root disturbance.
Sowing depth: 3-5mm
Spacing: 10-20cm for cut flower production, 30cm if ornamental.
(NOTE: if sowing in Autumn and you have poor drainage or experience particularly wet Winters, space 20-30cm to allow extra airflow and help reduce rot. They do not like to be wet for long periods, especially in cool weather. Seedlings and smaller plants handle the wet better than more mature plants so you can adjust your spacing depending on the time of year EG. my May & April successions will be 20cm apart but after that I will go to 10cm apart).
Days to germination: 7-14 days at 16-21 degrees (longer if cooler temps).
Days to maturity: 90-100 days if late Winter/Spring sown, approx. 140 days if Autumn sown.
Support: Corral with twine (stems can tangle so netting isn’t ideal)
Yield/stems per plant: Approx. 5 branching stems
Successions: At least 3 successions for ongoing blooms through Spring.
Example from my temperate climate: Succession 1 sown mid-April bloomed early-Sept, succession 2 sown late-May bloomed early-Oct, succession 3 sown early-August bloomed mid-Nov. I had a gap late-Oct so will be doing 4-5 successions next season. The bloom window for each succession is approx. 2-4 weeks depending on temperatures and weather.
Vase life: Individual blooms last approx. 5-6 days, but each stem is loaded with multiple blooms that open over the period of 10 days. For event work, they will hold up out of water for a few hours but you’ll notice the petals will start to reflex back after a while.
Harvest stage: Ideally when one flower on the stem is open and the rest are just starting to unfurl.
Harvesting tip: To speed up the process you can use a scythe or use your snips to cut a handful all at once.
CAUTION: All parts of the plant including seeds is harmful if eaten.
