These 4 potted plants are easy to grow and a great deal - one leaf can root into a whole pot

These 4 potted plants are so easy to grow that a single leaf roots every time, and growing one pot is already a win!
1. Peperomia obtusifolia (baby rubber plant)
Peperomia obtusifolia (baby rubber plant) - at flower markets people like to call it "Biyu" because its leaves are as green and lustrous as jade, making it very appealing. Peperomia obtusifolia also likes a warm, humid, semi-shaded environment, and must never be exposed to harsh sun or overwatered; it is very drought-tolerant and is an excellent green plant for homes and offices.
Propagation method: It is actually very simple - you only need one leaf. I have tried using three leaves of different forms: one whole leaf, one half leaf, and one leaf with a bit of stem, and in the end all of them rooted. You just need to insert the leaf of the Peperomia obtusifolia into crushed gravel and mist it regularly. Remember to keep it in a cool, shaded place, and it will basically root in half a month.
2. Pelargonium (geranium)
Pelargonium (geranium) likes a cool environment, with an optimum growing temperature of 5°C to 25°C, and grows best in spring. The leaves of Pelargonium have high ornamental value. Remove withered yellow leaves and spent flowers at any time and apply topdressing in good time, which can promote a second round of blooming and extend the ornamental period.
Propagation method: Both leaf cuttings and stem cuttings work. For leaf cuttings, select a robustly growing Pelargonium leaf, taking care to keep the petiole. The propagation medium can be larger-particle vermiculite or perlite, and of course clean sandy soil also works. Then insert the Pelargonium leaf, with the wound dried, into the growing medium. After that, take care to keep the growing medium at a suitable moisture level.
3. Sansevieria (snake plant)
Sansevieria (snake plant) is very easy to grow. It can purify the air in the home and also absorb harmful substances and harmful gases in a room. In addition, its leaves are thick and attractive, so many people like to grow it.
Propagation method: It is very simple. Pure sand, vermiculite, perlite, or even garden soil can all be used as propagation media. Insert the Sansevieria leaf into the pot (long leaves can be cut into several sections for propagation), water it, place it in a spot with diffused light, and wait patiently; it takes about 20 days or so before you can see sprouts.
4. Kalanchoe blossfeldiana (flaming Katy)
Kalanchoe blossfeldiana (flaming Katy) is also a type of succulent. It has many varieties and rich flower colors, blooms in winter and spring, and is especially appealing. Its care method is also relatively simple - just keep the environment warm and slightly dry and give it sufficient light. It is very drought-tolerant and does not need frequent watering.
Propagation method: The leaves of Kalanchoe blossfeldiana are fleshy and contain a lot of water, so they will not die quickly after being removed from the plant. At this point, if there is moisture in the soil, the leaf will grow new small plants, just like other succulents. Leaves for leaf cuttings should be dried first, and then you have two options. One is to insert the leaf into a growing medium, which can be a mix of vermiculite and perlite at a 4:1 ratio. The other method is water propagation - first let the leaf grow roots, and then insert it for propagation, which can improve the survival rate.
