I have a few cut roots of an aloe plant floating in water.
A few years ago, I met someone who had a whole bunch of aloe plants in his front yard.
He trimmed a plant and gave me a few stems.
I don't like to fuss with dirt and pots, so I have kept them floating in water for about three years.
I also have an Aerogarden.
I buy seed pods in February and if all goes well, the plants grow for 6 months.
I buy again in September.
I have salad greens, cherry tomatoes, herbs......
