Colocasia gigantea inflorescence

Day 1 Day 2 Day 3 Day 4

I've been growing Colocasia in my garden since the 1990s. It's a quick and easy way for a northern gardener to make one's yard look slightly tropical. I realize it's unlikely that that this is the first time a Colocasia has bloomed - but I never saw one until this past summer - the summer of 2020.

Here is a Colocasia gigantea grown from the one and only tuber I managed to get out of the ground and save despite a work marathon at the end of summer, 2019. The plant is growing in a 24-inch pot on my driveway, a driveway which gets bright sun most of the day. Besides the warm daily temperatures, the plant receives reflected heat from the asphault. I've kept the soil soaking wet and have fertilized at least once a week with liquid fertilizer (20-10-20) via a Dosatron. I was picking up lawn debris that that had moved to the driveway when I noticed the bloom. Notice how quickly it progresses. There were no other blooms at the time and so no chance for pollination.
