Special Care: 
plant in deep pot or in situ to avoid damaging long taproot; warm cycle should be hot 30-37°C/ Pat Windat saya: " They should be planted in moist soil mix and put in the refrigerator for at least 4 weeks, or what I do is mix them with a little moist Promix and put them in a pill container and refrigerate them for the same length of time; the seeds are big enough to be easily seen when planting. With this method I almost always have very good germination and it can be done a few months ahead and then planted at the right time. 20 degrees C. is fine after the cold period. I’ve been growing this plant for over 30 years, and this method works well."
