First soaked the seed in a glass of room temperature tap water, in total darkness, for 18 hours.
Drained about 75% water from the glass and poured the remaining water + seed onto a paper towel.
Folded the paper towel over the seed, and placed it inside a zip-lock bag.
Left the seed to germinate, in total darkness, for 36 hours.
After 36 hours the seed had sprouted a ~1cm taproot.
Planted the seed in a small cup, filled 2/3 with Plagron Royal Mix, and 1/3 with Canna Terra Seed Mix.
