About The Genus Alternanthera

This is a genus of flowering plants that are mostly herbs or subshrubs. It is a widespread genus that is commonly found in the tropical parts of America, mostly North America. However, some of its species are also found in Australia, Asia, and Africa.

These plants are notorious weeds; that is why these are also known as joyweeds. The species of this tropical genus are mostly terrestrial, but some species have aquatic plants too. These plants are known to produce allelopathic components that are harmful to other plants, such as crops.

Some of these species are edible, some are highly toxic, while some others are used as ornamental houseplants.

Origin and Distribution

These adorable compact plants are cultivars of Alternanthera ficoidea. These were first cultivated for their dense and bright colored foliage and exquisitely shaped leaves that make these shrubs a perfect ornamental plant for mass plantings.

Alternanthera True yellow, unlike its fellow species, is not originally from North America. It is a tropical plant that is mostly found in the wide tropical belt, mostly in South America, Asia, and Africa. These plants can also be grown in the tropical and warmer parts of Australia.

Alternanthera True Yellow Features

Foliage and Stem

These herbaceous plants have dense foliage that adds texture to the home gardens and works as a perfect backdrop for bold-colored flowering plants. These adorable plants grow new buds in early spring. These compact shrubs have chartreuse colored leaves. The bright yellow color gradually turns to greenish-yellow as the leaves grow older.

The small height makes this plant easy to handle and easy to place; you can place it anywhere inside your home, on your bedside table, or your kitchen table; you can also place it in hanging baskets.

Temperature Tolerance

This adorable Alternanthera True Yellow is a temperature tolerant plant that survives extreme heat provided that it is placed in well-drained and moist soil. It is a tropical plant, so it prefers warmer temperatures. But protect your Alternanthera from chilling temperatures and frost.

Humidity

Pressure

The small and compact size of Alternanthera True Yellow cannot bear external pressure from other big plants. If you are planning to place your True Yellows with your collection of large-sized, sturdy plants, make sure you give your Alternanthera enough space to grow, away from external pressure.

Disease and Pest Tolerance

This miniature species of the Amaranthaceae family is prone to slugs. The slugs are harmful to the dense True Yellow foliage. Slugs eat their leaves and stem, causing holes in them.
