Boobie Cactus Care Guide: Grow Your Own Spiky Beauties (Myrtillocactus Geometrizans)

If you’re a serious fan of succulents, you may have heard of the intriguing Boobie Cactus. This unusual and eccentric cactus has become more well-known due to its hardiness and ease of maintenance, in addition to its unusual appearance. We’ll go over all you need to know about the boobie cactus in this blog, including care instructions, propagation methods, and its official and scientific names.

Real name and Scientific name

The scientific and common names for the “boobie cactus” vary according to the type.  There are two primary competitors:

1. Myrtillocactus geometrizans:

  • Real name: Fukurokuryuzinboku (Japanese), Nipple Cactus, Breast Cactus, Titty Cactus, Blue Myrtle Cactus
  • Scientific name: Myrtillocactus geometrizans

2. Myrtillocactus coahuilensis:

Both kinds are known as “boobie cactus” because of their distinctive “bumpy bits.”  That being said, Myrtillocactus geometrizans is the more popular and well-known kind.

You can search for a few crucial differences to be positive of the species you have:

  • Stem shape: M. geometrizans has more rounded, pronounced bumps, while M. coahuilensis has flatter, elongated bumps.
  • Bloom colour: M. geometrizans have yellow flowers, while M. coahuilensis has reddish-orange flowers.

Its scientific name is ultimately either Myrtillocactus geometrizans or Myrtillocactus coahuilensis, depending on which species you have. Depending on the situation, you can refer to it by its scientific name or by its more popular moniker, “boobie cactus”.

Height and Structure

Boobie cactus (Myrtillocactus geometrizans) height can vary significantly, resulting in a variety of possible heights:

Average: Most mature boobie cacti grow to a height of 12 to 24 inches (30 to 60 cm). After receiving appropriate care for several years, you can see them contentedly settling somewhere in this range.

Factors influencing height:

  • Genetics: Certain plants have an innate tendency to grow taller or shorter.
  • Sunshine: Boobie cacti can grow to their maximum height when exposed to plenty of bright indirect sunshine.
  • Water and nutrients: Appropriate fertilisation and regular irrigation supply the vital resources needed for growth.
  • Pot size: While plenty of room permits stronger root development and maybe greater height, cramped pots can restrict upward growth.


  • Maximum height: Although uncommon, many well-established boobie cacti have been known to reach remarkable heights of up to 60 cm (24 inches) or even a little bit higher.
  • Dwarf cultivars: Rare cultivars like “Fukurokuryuzinboku” have a tendency to remain rather short, reaching a maximum height of approximately 8-10 inches (20-25 cm).

Recall that, depending on the maximum height that your particular boobie cactus may reach, regular care and patience are essential. Savour the trip and recognize each person’s distinct development!

How to propagate boobie cactus?

How to propagate boobie cactus?

Adding more of this oddball cuteness to your life through propagation can be a satisfying experience with your boobie cactus (Myrtillocactus geometrizans). Although propagating succulents isn’t the simplest task, it is achievable with the correct techniques and a little perseverance. Here are the two primary methods for growing more boobie cacti:

1. Stem cuttings:

  • This is the most popular and effective way to propagate boobie cacti.
  • Pick a mature, healthy boobie cactus with thick stalks.
  • Using a sharp, sanitised knife, make a 4- to 6-inch-long slice. Verify that there is at least one bump (areole) and that the cut is clean.
  • Give the cutting a few days in a dry, well-ventilated area to callus over. This lessens the chance of decay.
  • Plant the cutting, burying the end with the areole approximately 1-2 inches deep, in a succulent mix or well-draining cactus.
  • Use water sparingly, making sure the soil dries out fully in between applications.
  • Make sure the cutting is exposed to warm temperatures (preferably between 70 and 80°F) and bright, indirect sunlight.
  • In a few weeks, roots should appear with good care, and fresh growth will follow.

2. Seeds (less common but possible):

  • It can be difficult to find real boobie cactus seeds, so be cautious of false information you see online.
  • You should anticipate that only some of the seeds will germinate because germination rates are usually low.
  • Keep the surface of a well-draining cactus mix slightly damp but not soggy after you sow the seeds on it.
  • Provide warm weather and bright, indirect sunshine.
  • Patience is essential because germination can take several weeks or more.
  • After seedlings appear, treat them with the same attention as stem cuttings, making sure they have enough heat, light, and moisture.

Boobie Cactus Care Tips

Boobie Cactus Care

To maintain the happiness and health of your boobie cactus, follow these tips:

Light: Indirect, bright sunshine is ideal for boobie cactus. Try to get four or more hours of sunlight each day. While a plant that receives too little light may experience etiolation (stretched growth), too much direct sun can scorch the plant. You might need to add a grow light as a supplement throughout the winter in places with lower temperatures.

Soil: Use succulent or well-draining cactus soil when planting your boobie cactus. It takes proper drainage to stop root rot. For added drainage, you can also incorporate additional sand or perlite into the mixture.

Watering: Because Boobie cacti can withstand droughts, they don’t require regular watering. In actuality, the most frequent error individuals make with these plants is overwatering. In between waterings, allow the soil to dry fully. You might need to water your lawn just once a month throughout the winter.

Fertilising: If you fertilise at all, do it sparingly for your boobie cactus. It is adequate to use a small amount of cactus fertiliser in the spring once a year. Fertiliser overuse can scorch the roots.

Temperature: Boobie cacti are best grown in warm climates, namely in the range of 65 to 80°F (18 to 27°C). They can withstand lower temperatures as low as 50°F (10°C), but keep them out of the frost.

Repotting: When your boobie cactus outgrows its pot, or every two to three years, repot it. Select a pot with drainage holes that is just a little bit bigger than the root ball.

Diseases and pests: Boobie cactus are comparatively resistant to both. Nevertheless, sometimes scales or mealybugs can trouble them. Use neem oil or insecticidal soap to treat any bugs you find.

Propagation: Stem cuttings can be used for the propagation of boobie cacti. Before planting a cutting, about 4-6 inches long, let it callus over for a few days in well-draining soil. Till the cutting roots appear, keep the soil damp but not waterlogged.

Your boobie cactus should live for many years if given the right care. Savour its distinct beauty and infuse your house with something surprising!

Boobie Cactus Flower

Boobie Cactus Flower

Though its odd appearance is what makes the boobie cactus, also called Myrtillocactus geometrizans, so beloved, its blossoms can be equally lovely, despite their rarity. The following is what to anticipate from a flowering boobie cactus:


  • Size: The flowers typically have a diameter of 1-2 inches (2.5–5 cm), making them comparatively tiny.
  • Form: They feature five outward-facing petals and a bell- or trumpet-like shape.
  • Colour: The flowers are usually a vivid yellow, although some varieties may include hints of orange or red.

Bloom Time:

  • Frequency: The unfortunate truth is that boobie cactus blossoms don’t happen very often. They seldom bloom for a long time—typically only once per few years or longer. Age, stress levels, and growth circumstances are only a few of the variables that may affect this.
  • Season: Spring or summer are the best times to see blooming on cacti because they get enough heat and sunlight.


  • Fragrance: The blooms of boobie cacti are not very fragrant, in contrast to many other cacti flowers.
  • Attracting Pollinators: The blooms’ open shape and vivid yellow color draw pollinators like butterflies and bees, which promotes the growth of seeds.
  • Fruiting: The boobie cactus may produce tiny, green fruits near the base of the flower following flowering. Although these fruits are theoretically edible, people rarely use them in cooking due to their bland or even somewhat unpleasant taste.

Boobie Cactus Seeds

The boobie cactus (Myrtillocactus geometrizans) has a striking appearance due to its characteristic “boob-like” stalks, however cultivating them from seeds can be more difficult than with other succulents. The following details concern the seeds of the boobie cactus:


  • It can be difficult to find real boobie cactus seeds. Online vendors are offering to sell them, but be wary of false advertising and growth claims that are too good to be true. For added assurance, look for trustworthy suppliers who specialise in uncommon succulents.
  • Seeds labelled “live” or “fast-growing” should be avoided because boobie cacti may not respond well to these claims.


  • When compared to other succulents, the germination rate of boobie cactus seeds is rather low. Even under ideal circumstances, just some of the seeds should sprout.
  • Sometimes germination takes up to a month, or even longer. The secret is to be patient!

Growing Conditions:

  • Ideally, the temperature should be between 70 and 80°F (21-27°C) in a warm, sunny area.
  • To prevent rot, use a succulent soil mix or well-draining cacti.
  • Retain a slightly damp but not drenched soil. Over-watering seeds is bad for them.
  • Give the seedlings enough light, but keep them out of the direct midday sun, which might scorch them.

Care for Seedlings:

  • The seedlings won’t immediately resemble the mature boobie cactus. They will have less noticeable bumps and longer stems at first, giving them a very different appearance.
  • The seedlings are delicate, so handle them with care.
  • Ensure that they get the right amount of light, water, and temperature as they grow.
  • The requirement for repotting will vary according to how quickly they develop, but in general, don’t repot until the pot gets too tiny.
