Other Plants That Grow From Rhizomes

feature image

A rhizome is the main stem of a plant that grows horizontally underground. They also have the ability to grow their roots down into the earth and shoots up above the surface.

Rhizomes are annoying pests because even if a tiny piece gets separated from the original stem, they grow into a brand new plant.

This property means that they are extremely difficult to remove and if not taken care of properly, the situation can become even worse.

Japanese Knotweed is a known rhizome plant, but you may not be aware of others. Here is a list of some other plants that grow from rhizomes.

Creeping Charlie

creeping charlieAlso known as ‘ground ivy’, Creeping Charlie is a perennial weed that can be tricky to control and kill.

It has a square-shaped stem that grows up to two feet tall can it can be identified relatively easily. This is because the leaves come in a variety of colours; they can range from purple to dark green and will spread across the lawn.

Creeping Charlie spreads from seeding and rooting at the nodes and rhizomes.

If the pest is not removed from the lawn and you end up mowing over it, there is a good chance it will spread over a wider area than before.

Once this happens, the only option may be to kill everything in and around the infected area.

This becomes problematic if it surrounds an area close to a patch of flowers or shrubbery you may have planted for decoration.

Horsetail

horsetailAnother common weed found in UK countryside and gardens, horsetail is a pest that flourishes in damp soil conditions.

During the early stages of growth, horsetail spores become rhizomatous and rapidly develop long layers of horizontal rhizomes while the roots grow deep into the ground.

Once it has established itself on the landscape, it becomes resistant to dry conditions.

Horsetail is difficult to control by cultivation because new stems regenerate from rhizome fragments and from tubers.

Furthermore, there are no known biological control agents that have proved effective.

Stinging Nettles

stinging nettleAnother common garden pest, stinging nettles take up a lot of garden space and can cause rashes when coming into contact with it.

Stinging nettles usually grow to about three to four feet tall. They often grow into one large group with bristles extending from the stems and leaves. The leaves themselves tend to look quite sharp with their arrow-shaped figure.

Their favourite habitat is garden borders. In fact, just as the presence of moss plants is an indicator of compacted soil, the presence of stinging nettles signifies that the soil is fertile and provides a great living environment.

They need to be removed from the garden to prevent being stung. However, if a rash does develop, there will usually be yellow dock plants nearby. Rub the leaves on the stung area to act against the toxins released by the nettles.

Poison Ivy

Poison Ivy

One of the most important plant to identify on this list is poison ivy to prevent from getting into contact with it. While the leaves are the most toxic part of the plant, any part of it can cause an allergic reaction.

Young poison ivy plants often start out in spring with orange-red leaves. As the plant matures, the leaves turn green and the plant itself will grow to about two meters tall. Poison ivy plants also flower with buds that form clusters and look like tiny specks of green.

Poison Ivy plants also grow berries, which are just as toxic as the rest of the plant. An identifying feature of poison ivy is the colour of its mature berries. When they ripen, they turn from a pale green to an off-white colour.

In the winter, it’s common to see hairy poison vines climbing up tree trucks. The hairs cling to the surface, allowing the plant to climb its way up.

Ginger

Ginger is a flowering plant whose rhizome or root is used as a spice or as an ingredient in medicine. It is a perennial plant that grow to around a meter in height with long, narrow leaves.

The flowers are in dense cone-like spikes about 1 inch thick and 2 to 3 inches long that are composed of overlapping green bracts, which may be edged with yellow. Each bract encloses a single, small, yellow-green and purple flower.

The rhizomes themselves vary in colour, ranging from a dark yellow and orange to light brown.

To harvest the plant, the ginger rhizome is gathered where the stalk begins to wither. It is then scaled in boiling water and washed to kill it and stop it from sprouting.

Turmeric

Turmeric is a member of the ginger family. It is harvested for its rhizome and used as a flavouring agent in many Asian dishes.

At the top of the inflorescence, stem bracts are present on which no flowers occur; these are white to green and sometimes, tinged reddish-purple, and the upper ends are tapered.

Turmeric plants can reach up to a meter tall and its rhizomes are often branched out in a number of different directions. Similar to ginger, the turmeric rhizome varies in colours yellow to orange.

These colours have also made it popular in Eastern culture to be used as a fabric dye.

In recent times, turmeric has been studied in a number of clinical trials, in particular for treating a number of human diseases.
