Is This Houseplant a Cactus or a Succulent?

I bought this from a shop last year, I don’t know whether its a cactus or a succulentLearn the definition of a succulent plant and why they are called a "fat plant." or some hybrid? Please can you help identify what it is so I can read up on it?

Thank you in advance 🙂



Hi Leem,

How to grow, identify, and care for Eve's needleCactus

Your plant is called a Austrocylindropuntia subulata. The simple common names are:

Eve’s Needle Cactus, Eve’s Pin Cactus, Long Spine Cactus.

Austrocylindropuntia is in the cactus family. They have tuberous roots, cylindrical stems, and round cylindrical leaves about 5″ in length.

Light: Eve’s Needle Cactus needs very bright lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light. but no direct sun. The heat from direct sun with soften the leaves.

Water: During spring and summer, allow the soil to dry out before watering. Over watering is the main reason this plant dies. During the winter, decrease your water even more. Water monthly when the soil is very dry.

Soil: Use a Cactus soil that is sandy and drains quickly.

Temperature: Cool temperatures during the winter when the plant is resting (50°F/10°C)

fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small.: Feed every 2 weeks when the plant is actively growing with a cactus plant food
