Lithops plants (living stones): Lithops are fascinating little succulents. Sometimes called split rocks or pebble plants, living stone plants are extremely drought-resistant and are widely popular in low-water gardens in desert regions.

They can be grown both indoors and outdoors, but outdoor growers should be careful that they don't get too much water. It's estimated that there are at least 37 species of lithops, and around 145 varieties. More varieties are regularly discovered or bred by hybridization.

Marimo balls from moss: It sucks Up Nitrates and Other Nasties. Like live plants, moss balls absorb nitrates. But—also like plants—it's usually not a large amount. The ball would make a difference only if it were kept in just a few gallons of water. Still, any nitrate absorbent is a benefit to your tank's ecosystem. Moss balls are also like little filters, sucking up debris and small amounts of ammonia and phosphates. Like plants in general, moss balls suck up CO2 and release oxygen in the water. If you don't like noisy air stones, some Marimo moss balls are a great addition to help you oxygenate your tank. While gravel and filter media is the most valuable seeding items for a new tank, the Marimo moss ball, like many plants, has colonized beneficial bacteria on its surfaces, and can make for great seeding material. I wouldn't put one in a filter (in fear of hurting the moss ball) but they can help with the nitrogen cycle. A lot of aquarium plants don't do so well in high pH water, but this doesn't affect moss balls. I have kept moss balls in pH of 8.4, and they remained healthy. Goldfish are known to eat anything in their paths, so don't be surprised if your goldfish tears this ball to shreds.

Black succulents (Sinocrasula yuancensis): Sinocrassula yunnanensis, is native to south western China (Yunnan province), north and south of Burma, north-western India, Sumatra and Bhutan.

Black succulents exist, guys, and they're the perfect home decor addition to match our cold, dark souls. This species of succulent is known as Sinocrassula yunnanensis, a type that features densely packed clumps of rosettes. Its pointed leaves (which somewhat resemble mini pine cones or hedgehogs) are typically a dark green hue, but that color is often so dark that it actually looks more like black than green.

Dolphin Succulents: Remember the bunny succulent plants?

Hoya Kerrii: There are a few Hoya's out there which make ideal houseplants, Hoya kerrii or the Sweetheart Plant is one of them. Hoya kerrii or as it's often called the Sweetheart Plant Its become increasingly popular in recent years but you may still struggle to find information or care tips about it.

Trachyandra: Trachyandra Tortilis is a succulent that has an unusually long life span, making it even better for people who want a plant that lasts longer. It is best grown indoors in a well-lit room with well-draining sandy soil. It grows up to 25 cm tall and has a green basal leave of 10 cm length that can be up to 2 cm width. Unlike other succulents the Trachandra species have leaves that filiform or linear. The plant folds up once it finally flowers it becomes pale pink.

Rose Succulents: Called Greenovia Dodrentalis, these succulents have curved layered petals that make the plants look just like roses. Mostly they're found in the Canary Islands but we would say they belong somewhere in a fairy tale because of how unique and magical they look! Keep on scrolling to check out some pictures of this stunning rose-shaped succulent.

Crassula Umbella: Crassula are easy to grow, but they are susceptible to mealy bugs and fungal diseases. As with all succulents, overwatering is sure to be fatal, so err on the side of too dry rather than too wet. Never let your Crassula sit in water. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes. Crassula are generally started by division, offsets or leaf cuttings. Plants can be easily propagated from a single leaf: sprout leaves by placing them into a succulent or cacti mix, then covering the dish until they sprout.

Euphorbia Obesa: Euphorbia is a large group of succulent and woody plants. Euphorbia obesa, also called baseball plant, forms a ball-like segmented shape that is adapted to hot, arid climates.

Fishbone Cactus: The scientific name for the plant is Cryptocereus anthonyanus (syn. Selenicereus anthonyanus), and is a member of the night blooming cactus family. Best known for its long, arching stems coated with serrated leaf nodes, fishbone cactus is found in its habitat in groups, which hang from trees. The plant originates in Mexico, where tropical rainforests create a moist, humid environment. It is commonly found in garden centers as Ric Rac cactus or sometimes orchid cactus. Rarely the plant will bloom with soft pink flowers that open at night and last only one day. Fishbone cactus houseplant enjoys similar growing conditions as its cousin, the orchid.

Nerve Plants: It's scientific name is Fittonia Verschaffeltii (Fittonia albivenis). The plant needs to be kept constantly moist with a high level of ambient humidity provided by frequent misting or by growing it in a tray filled with pebbles and water. Ideally, most growers find it's easiest to grow these lovely but temperamental plants in terrariums or covered gardens where they can get the high humidity and diffuse light they love so much. Fittonia grows well in standard potting soil with a peat-moss base. The soil should retain some moisture but should also drain well. During its growing season, feed plants weekly with a weak dose of liquid fertilizer formulated for tropical plants. A balanced 5-5-5 fertilizer diluted to half strength is a good formulation.

Red Aglaonema: One of the easiest of all houseplants to grow, red aglaonema is also one of the most stylish.

Its colorful foliage makes red aglaonema a perfect home-decor accent. It's gorgeous on desks or tabletops, as well as coffee tables and side tables in dens, living rooms, and bedrooms.
