Banksia grandis

Banksia grandis, known as Giant Banksia, reaches a height of 5 - 10 m. It is native to Western Australia. The leaves are very large, up to 45 cm long. Large cylindrical flower spikes, 35 cm high, yellow with cream.

Use Jiffy peat soaking pots for sowing, allow to swell in water and place in a plastic pot. Alternatively, commercially available seed substrates can also be used.

Spread a few seeds on the peat soaking pot and cover them thinly with the sowing substrate (about 2 mm).

Then place the plastic pot in a zip lock bag - with a pot size of 6 cm, a zip lock bag measuring 120 x 170 mm is recommended. Put enough tap water with a few drops of universal fertilizer in the zip lock bag so that a few mm of water remain after the substrate has been soaked up. 
Location: on the windowsill or in a mini greenhouse in partial shade, during the day the temperatures should be around 24 - 28 C, at night a little lower at 20 - 24 C. The resulting microclimate creates ideal germination conditions
