Opuntia fragilis aka Loose Prickly Pear

Taxonomy

Opuntia fragilis, also known as brittle pricklypear or little prickly pear, is a sun-loving cactus that is native to Western North America and some Midwestern states like Illinois, Iowa, Wisconsin, and Michigan. It can also be found in several Canadian provinces and as far north as 56°N latitude in British Columbia. The cactus has oval or cylindrical flattened joints that are whitish-green and smooth, measuring up to 3 inches in length. These joints have 5 to 8 greyish-brown tipped spines of 1 inch extending from multiple small, white areoles, and they drop off easily. The species bears pale yellow flowers in the summer, which rarely produce dry, spiny fruit. The genus has the largest membership of sun-loving species, and some species have been banned in Australia because of their rapid growth. The brittle prickly pear is a popular houseplant that requires very little water to thrive and does well in long-lasting, direct light. It should be placed less than 1 foot from a window. Additionally, there is an isolated and possibly genetically unique population in Eastern Ontario, known as the "Kaladar population."

How to care for Loose Prickly Pear

Difficulty

Even if you don't have a green thumb, you can successfully care for Loose Prickly Pear due to its easy-going nature.

Water

Loose Prickly Pear does best in dry soil and should only be watered sparingly.

Soil

To ensure the health of your Loose Prickly Pear, it's crucial to use a potting soil that won't hold too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and organic matter for nutrition is ideal. Adding a few handfuls of perlite to store-bought cactus soil is an easy way to create this type of soil mix.

Lighting

Loose Prickly Pear thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Brittle Prickly Pear.

Dormancy

During the wintertime, it's common for Loose Prickly Pear to go dormant and their growth may slow down, so waterings should be spaced out more.

Toxicity

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Humidity

Loose Prickly Pear prefers dry environments, so misting the plant to provide extra humidity and allow water to linger on the leaves can create an ideal environment for fungi that can be harmful.

Fertilizer

The growth rate of Loose Prickly Pear is slow and it doesn't necessitate additional fertilizing. By changing the soil in its pot annually, the plant should be provided with adequate nutrition. It is crucial to keep in mind that plants derive their energy from the sun, not fertilizers.

Growth-pattern

Loose Prickly Pear grows vertically and new growth emerges from the top of the plant.

Region of origin

Loose Prickly Pear’s native range is the Americas.
