Can I collect viable seed from Protea?
Yes, however this is difficult and not always successful. Flower heads must be left on the plant for 9-12 months after flowering for seed to develop. Cut and then dry the flower head after this time. Seeds may be found in the base of the flowerhead. Plant out seeds as soon as possible in a coarse propagation mix. Seeds from the Protea genus germinate in 6-10 weeks.
