Phytolacca dioica aka Omb
Taxonomy
Phytolacca dioica, also known as ombú, is a large evergreen tree native to the Pampas of South America. It has a unique umbrella-like canopy that can spread up to 15 meters in diameter and a height of 18 meters. The trunk of the ombú is derived from herbaceous ancestors, resulting in anomalous secondary thickening instead of true wood, making it soft and spongy enough to be cut with a knife. Despite its fast growth, its wood is not durable, but it is easily manipulated in bonsai art. The tree is dioecious, with male and female flowers on separate plants and is pollinated by the butterfly Doxocopa laurentia. Its leaves have laxative or purgative properties and are not grazed by cattle due to its poisonous sap. The ombú is a symbol of Uruguay and Argentina and is a minor invasive species in South Africa.
Bella sombra, on the other hand, is a long-lived evergreen tree that can grow up to 25 meters tall, with a unique swollen base that can grow up to 4 meters in diameter. The tree contains up to 80% water in its trunk and branches and is sometimes harvested for food, medicine, and ornamental purposes.
Finally, the North American pokeweed is a super rare houseplant that requires regular watering and direct light to thrive. It prefers soil that retains moisture and can benefit from organic fertilizer during peak growing season.

Omb, Umbratree, BelhambraHow to care for Omb
Difficulty
With a bit of knowledge and dedication, you can successfully care for Omb, making it a rewarding choice for those seeking a moderate challenge.
Water
Omb should be watered regularly, allowing the soil to dry out between waterings.
Soil
When growing Omb, it is important to pay attention to the soil type you are using. This plant is very sensitive to dry soil and needs a potting soil that retains moisture. A good soil should still be well-draining and contain lots of organic matter. Coco coir or sphagnum moss are great options to provide the Umbratree with the nutrients and moisture it needs. The added organic matter will also help the soil retain water and prevent the Omb from drying out too quickly. Before planting, make sure to mix compost or manure into the soil for extra nutrients. Also, make sure to water the Omb regularly, making sure to keep the soil evenly moist but never soggy. With the correct soil and watering regimen, the Omb will thrive and bring lots of beauty to your home.
Lighting
To ensure optimal growth, the Omb prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
