Wanting to have more houseplants in my flat and knowing that Spider plants (Chlorophytum comosum) are very easy to grow, I … ahem … pinched a couple of spiderlings from a much neglected plant in the office toilet and popped them into some water to get them started. I knew they would quickly develop roots but their speed amazed me. The photos below show their development after 2 days, 4 days, 6 days, and 16 days. Time to buy some potting mix, me thinks!
