Common Amsonia Varieties – Types Of Amsonia For The Garden
Amsonia Tabernaemontana: The Blue Star Amorphophallus (Amphiphylum)
The blue star amorphophallus (amphibophile) is one of the most common types of amonas in nature. They are found in tropical rainforests, but they have been known to grow as far north as Canada. They feed mainly on small invertebrates such as crustaceans and worms. Their diet consists mostly of these tiny animals, which they then eat with their mouthparts called chelicerae.
In order to get enough food from the prey, they need to move fast because it takes them several hours before they can digest all the food that they catch. They also use their claws to dig into the soil or other hard substrates where they live.
They are not very big, so they do not pose any threat to humans. However, if you happen to come across one in your garden, it would be best if you did nothing at first. Because of their speed and agility, they may easily escape your attention until it’s too late! If you see one in the wild, don’t panic; just leave it alone!
Amsonia Hubrichtii: The Blue Star Amsonia (Amphiphylum)
The blue star amsonia is also commonly known as the blue star in the wild. However, it is much less common compared to other types of amsons. It is native to Texas and other states in the south west of the United States. There are fears that this plant may become extinct in some states due to habitat loss and other issues.
The blue star amsonia can grow up to a size of 3 feet. It is a shade-loving groundcover more than anything else. It has a tendency to flower between the months of April and May, some time after it has finished flowering it grows a woody fruit which then ripens by August.
It flowers with small white petals with a yellow center. The leaves of the plant are heart-shaped and are between 2-6 inches long. The blue star amsonia is very easy to take care of and can thrive in a variety of different conditions. It prefers to live in soil with good drainage, but it will grow in soil that contains clay as well.
Even though it can grow in almost any type of soil, it does not tolerate drought conditions well at all.
Amsonia Blue Ice: The Blue Star Amsonia (Amphiphylum)
The blue ice amsonia is a very rare type of amsonia. The plant is only found in the states of Alabama and Arkansas, and it is considered to be critically endangered in both states. There are threats that this plant may become extinct in the future because it is only found on a few isolated mountains.
The blue ice amsonia gets its name due to the fact that it has a lot of ice-like patterns on the leaves and stems. It flowers during the month of April to May, the flowers are a pale bluish color in appearance. The plant then produces a round almost orange woody fruit after it has finished flowering.
The blue ice amsonia prefers soil that drains very well such as sand and loose rocks. It also prefers soil that contains high levels of organic matter. It does not grow in colder conditions and will begin to lose its leaves during the winter months.
The blue ice amsonia is threatened by recreational activities, such as off-road vehicle usage and hiking. There are also threats such as climate change as the temperature rises, this causes the plant’s preferred habitat to shrink rapidly.
The blue ice amsonia is a low growing plant, it tends to stay between 6 inches and 1 foot in height. It has heart-shaped leaves that grow in clusters, the plant’s blueish coloring makes it quite easy to spot in the wild.
Bidens Tripartita: The Riflebird Flower
The riflebird flower is one of the most commonly seen wildflowers in Australia. However, in terms of distribution it is not all that common. It can only be found in a few select areas along the coast of Australia. The majority of these areas are within the state of Queensland, with smaller populations in the states of New South Wales and Western Australia.
When the riflebird flower is in bloom, it is quite easy to spot as its bright orange flowers contrast very well with the green leaves of the plants. The flowers themselves have five petals and resemble stars in appearance. The riflebird flower tends to grow a few inches above ground level and can get to be up to about a foot in height. The leaves have a jagged appearance and grow in clusters at the base of the plant.
The riflebird flower prefers soil that is rich in nutrients, it also grows in soil with high levels of acid. It does not grow well in compacted soil, if there is no room for its roots to spread out.
