LEUCADENDRON macowanii

An attractive fast growing single-stemmed shrub with dark green Acacia-like leaves. Both male and female plants produce bright yellow flowers in spring with the male flowers the most attractive. The female plants produce attractive reddish-brown cones in late summer. An attractive plant that is excellent for group planting in landscaping.
Both male and female plants produce flowers during spring and early summer. The female plants' flower-heads develop into attractive cones containing the seed. The flowers, cones, and foliage are widely used in flower arrangements. Extremely rare and endangered in the wild.

Leucadendrons are dioecious, separate male and female plants. Both the male and female flowers occur in dense heads at the branch tips with the male flowers the most attractive, only the female flower will produce cones and seed.

Prefers a well-drained soil with regular watering in a sunny position. Wind resistant, frost tolerant when established.

Grow notes:

The best time to sow is usually autumn or spring when the temperature range is between 16-22°C and there is a difference of day and night temperatures of around 12°C.
If your summer is hot and dry and your winter is moderate and wet the best time to sow is in autumn.
In colder climates with less harsh summers, it is usually better to sow in spring.

1. The growing medium should be well-draining but should remain damp between watering.
2. Sow seed 6mm deep. Vermiculite is a good medium to use to cover the surface as it helps retain moisture and controls the temperature. 
3. Keep moist but not too wet as the seed may rot. Do not let the growing mix completely dry out. 
4. Germination should occur in 21-60 days depending on the temperature and conditions. 

Pre-treatment of smoke is recommended:
Members of the Proteaceae are responsive to pre-treatment of smoke. Although germination will often occur without smoke treatment it has proved to be beneficial in reducing the number of days to germination and increasing germination rates in many species of the Proteaceae family 
Smoke treatments are simple and can be undertaken either by soaking the seed overnight or by applying it to the surface after sowing, both provide good results. Smoke treatments are available by clicking here.
