I DO not have a green thumb. If there is a plant Heaven I will have contributed many of its occupants.
But I love house plants and was impressed by an argave grown by my cousin in a large glass candle jar full of water. This as rather clever as argaves are desert plants – from southern USA, Mexico and Central America – and not keen on too much water http://www.abc.net.au/gardening/stories/s1866768.htm. I tried about a year ago to grow a jarred argave but instead ended up with a distinctly deceased specimen rotting in the water. Bravely I have tried again under long-distance tutelage from my cousin and, a month on, I have a healthy plant sprouting multiple roots in a tall glass jar. I’m not up to my cousin’s skill level yet but it’s looking promising.
