I live in subtropical Hong Kong. Is this some kind of tiny flower dandelion? Is has floating seeds, which grow in very small clusters about the same size as the flowers or smaller.
I can't be sure about the growing times. I threw so many random seeds in the ground and ignored everything and just moved everything around and am starting to get organized and serious about gardening.
I took a whole bunch of seeds and potted them hoping to grow a dozen or more. Would be great if it was not poisonous like my other purple weed I asked about.
