The best part about these low-maintenance plants? You can never overwater or underwater them — the number one killer of house plants — because they grow in water. As an aside, with each of these plants, they can develop root problems as they mature. Just make sure to keep an eye out for it. If that does happen, shift them from water only to water/gel beads, or use expanding clay as a base layer so they can get oxygen. When root problems occur in plants grown in water only, the cause is mostly a lack of oxygen.
1. The Wandering Jew.
This is a great looking green, purple and silver plant. It has to be something to include as part of any ornamental collection. Let it trail over the end of a bookshelf or make it a centerpiece on a side table or coffee table. All you need to propagate these are as many stems as you want from an already matured Wandering Jew. How many? Depends on how big a plant you want.
2. The Purple Heart Plant.
If you’ve read that this in the same family as the Wandering Jew, you’ve been misled. It’s a different species. The only commonality this has with the aforementioned is they’re both purple, Albeit different shades. That makes it a spectacular plant to have on display near your Wandering Jew. The propagation method is the same too. Take one or more stems, cut from above the highest leaf and snip the leaves at the bottom. The only part to put in water is the nodes.
3. Sweet Potato Vine.
Start with a sweet potato (organic’s best because some spray these with a sprout retardant before selling them). Here’s what you need: One sweet potato – One glass jar big enough to put it in – A few toothpicks. What you do is put the toothpicks into the sweet potato about half way; They’re going to be holding the potato up in the jar (They rest on the rim of the container). Only the bottom half is in the water. Sit the glass jar in a sunny spot, keep the water topped up, and give it a few weeks for leaves to form.
4. The Coleus Plant.
Varieties of coleus are aplenty and all are very distinct. Either one will grow in water alone, provided you use a liquid fertilizer. These aren’t as tough as they look. Rooting a coleus in water is a little different from all the other plants. The reason being, there’s two types of stems on a coleus plant. Your typical stem has a node on the end and an apical stem has a bud. Think of the apical stem as a secondary stem.
5. The Lucky Bamboo Plant.
In Chinese culture, the Bamboo plant is for luck, but you have to know your Feng-Shui numbers. Three is a go-to number: Earth – Water – Wood. Or in the Western culture, it’s become known for: Wealth – Prosperity – Happiness. The great part of growing the lucky bamboo plant is you only need a shallow dish. Just enough water to keep the roots covered. That can be in a small dish lined with pebbles, so long as the roots are in the water.
