Success with Stapeliads (Carrion Flowers)

Stapeliads, succulents from South Africa and Arabia, produce some of the most unusual flowers of any in the plant kingdom. These star-shaped blooms use color, texture, and odor to resemble decomposing meat. Your dogs may find them fascinating (mine do). Fingerlike leaves of stapeliads are generally soft, upright and four-angled, with ridged edges. Points along stems are safe to touch.

"One of the dirty tricks we succulent geeks like to pull is to have someone take a big whiff of the unusual starfish flowers of a stapeliad," Jeff Moore of Solana Succulents nursery says in his book, Soft Succulents. "The plants have opted out of the bee pool and decided to use flies as pollinators, hence the smell of rotting flesh.”

Stapeliads, Jeff adds, “are mostly nice little spineless, often fuzzy collections of small columns, but the attraction is really the diverse array of alien-looking flowers. They even look cool as puffed-up pods a few days before they peel open.”

Stapeliad Care and Cultivation

Considering how fascinating they are, it's a wonder stapeliads aren't more widely cultivated. Jeff speculates that they're too equatorial for most collectors, and need to be greenhouse-grown. Here in Southern CA, a handful of species do well as potted plants, and several (notably Stapelia gigantea) survive in garden beds.

  • Water: As with most succulents, keep soil barely moist. Water once every week or so in summer; less in fall and winter depending on the weather; and minimally in winter. Protect from soaking rainstorms. Stapeliad collector Jen Greene advises in her article for the San Diego Cactus & Succulent Society newsletter: “Water when stems start to wrinkle and shrink or droop. It’s easier to rehydrate the plant than to save it from rot.”
  • Flowers: Jen also applies half-strength fertilizer to encourage prolific blooms. She uses dilute fish emulsion, which she says smells worse than the flowers! The Henry Shaw C&SS advises, “for maximum floral display, repot frequently. Flowers appear only on newer stems, so older stems can be removed without losing flowering potential.”
  • Propagation: Take cuttings in spring as the weather warms. They’ll produce roots when laid flat on succulent soil. Jen keeps soil damp so it doesn’t turn “into dust until the cutting has firmly rooted.” She wiggles it to check; a rooted cutting will feel like it has “grabbed-on.”
  • Soil should drain exceptionally well. Use a 30-30-30 blend of cactus mix, coarse sand (like decomposed granite) and pumice.
  • Pests and problems: Main enemies of stapeliads are mealy bugs and black rot. If you see any patches of the latter, remove them immediately. Drench the plant with fungicide and repot in fresh soil.

Stapeliads to get you started

Most stapeliads have a growth spurt in late fall and early winter, which also is when they bloom---and IMHO, the flowers are the main reason to grow them. Shown here are readily available varieties, some of which I grow in my own garden (Southern CA Zone 9B). These are, however, a mere fraction of the species that exist (and tend to be more finicky).

Many thanks for the use of their photos: collectors Pat Roach and Rich ZehMountain Crest Gardens nursery, and newsletter subscriber Ray Burge. 

Hoodia gordonii (c) Debra Lee Baldwin

Hoodia gordonii

Hoodia gordonii: Native to arid habitats in South Africa and Namibia, this succulent has long been used by indigenous peoples of South Africa to assuage hunger pangs on Kalahari hunting trips. Because of extreme interest in the genus as an appetite suppressant, trade is restricted.

Hoodia parviflora Rich Zeh photo

Hoodia parviflora

Hoodia parviflora: This largest species of Hoodia  can grow to the size of a tree — as tall as 6 or 7 feet. Its small maroon flowers are known for their particularly obnoxious smell.

Huernia kennedyana

Huernia kennedyana

Huernia kennedyana: It's known as the "Humpty Dumpty" huernia for its egg-shaped (globose) stems. Dark red indicates summer stress; stems will revert to green in winter. Tiger-striped flowers are about an inch in diameter.

Huernia longituba (c) Debra Lee Baldwin

Huernia longituba

Huernia longituba: The species name means---no surprise---"long-tubed," and refers to the plants' elongated, bell-shaped blossoms. Native to Botswana. Btw, those dots are bumps (tubercles).

Huernia mccoyi MCG

Huernia mccoyi

Huernia mccoyi: One of the easier stapeliads to grow, it also flowers profusely. Blooms, which form near its base, are five-pointed funnels. Atypical of stapeliads, this one is odorless.

Huernia procumbens

Huernia procumbens: Produces large, sea-star-like, pale yellow flowers with a raised burgundy ring at their centers. "Procumbens" refers to the sprawling, trailing habit of the plant's many stems.

Huernia thuretii, photo by roachpk

Huernia thuretii

Huernia thuretii ranges in color from apple green to deep burgundy. It produces pale yellow, multipointed flowers with a recessed center cup.

Huernia thuretii var. primulina: Green stems become tipped with pink and purple when grown in bright sunlight. Yellow flowers sprout from the base to form cupped stars.

Huernia zebrina

Huernia zebrina (Lifesaver plant)

Huernia zebrina has a prominent center ring that resembles a red candy Lifesaver. Surrounding the raised ring, pale yellow petals banded in red form five points---actually ten, if you count the mini-ones midway.

Huernia Zebrina variegata photo by roach-I

Huernia zebrina has a rare variegated form. This one, in the collection of Pat Roach, came from Rojas Succulents in Fallbrook, CA.

 

Orbea sp.(c) Debra Lee Baldwin

Orbea sp.

Orbea sp.: I've included this because it's a charming stapeliad that I'm pretty sure is an orbea. However, its owner (at the C&SS show where I shot it) didn't know the species. It's also found nowhere online. So if you recognize it, would you LMK? Flowers are about an inch across and leaves are stubby.

Orbea variegata, photo by Ray Burge

Orbea variegata

Orbea variegata: Forms a dense cluster of stems. Leathery-petalled flowers up to three inches wide are pale yellow and speckled with burgundy. Note the prominent five-pointed star at center---it's loaded with pollen. Like orchids, stapeliads coat insects with pollen which they transfer as they move on to the next flower.

Pseudolithos cubiformis (c) Debra Lee Baldwin

Pseudolithos cubiformis

Pseudolithos cubiformis: This is one of the craziest-looking plants. Its name means "false stone" and I see why, but it reminds me of Turkish delight candy. Or perhaps a petit-four. It's native to Somalia, and it was only while researching this article I discovered that Pseudolithos is a stapeliad. Those flowers! Btw, I shot this at Petra Crist's Rare Succulents nursery.

Stapelia gigantea (carrion flower) (c) Debra Lee Baldwin

Stapelia gigantea 

Stapelia gigantea, with flowers up to 10 inches across, has some of the largest blooms of any succulent. Leaves grow to about 8 inches tall, and are colony-forming. One of the few stapeliads that will grow in the ground in Southwest gardens.

Stapelia grandiflora in the ground

Stapelia grandiflora has meat-colored petals and fur, the better to persuade flies that it's a putrescent animal.

Stapelia grandiflora flower, after flies laid eggs (some of which have hatched) at its center.

 

Stapelia hirsuta (c) Debra Lee Baldwin

Stapelia hirsuta

Stapelia hirsuta: I love when a species name is helpfully descriptive. "Hirsute" means "hairy." Only thing is, we've seen hairier stapeliads. However, this one does a superb job resembling carrion. It's native to the far west of South Africa, where it receives winter rainfall similar to Southern California's.

Stapelia leendertziae (Black bells) photo by roachpk

Stapelia leendertziae (black bells)

Stapelia leendertziae's dark maroon, bell-shaped blooms give the plant the common name "black bells." The flower is an impressive 4 inches in length.

Stapelia paniculata ssp. scitula

Stapelia paniculata ssp. scitula, despite looking like furry beef jerky, doesn't smell like other stapeliad flowers---a good thing.

      Thank you for a lovely comment, Celest! Which reminds me, I need to move my collection to a warmer spot. They’re going to the east deck against a wall that’ll retain warmth and keep them cozy all winter, where they may get a little rain but not much.

      • sandra ann bedard on November 7, 2022 at 11:10 am

        Thanks for sharing. I think I actually have one of them growing in a pot. It sort of droops over the side and trails, but then the flowers bloom at the ends.

      Jim, this makes my day—thank you for a terrific accolade. Makes it all worthwhile!

  3. Nancy L Lindsay on November 5, 2022 at 3:58 pm

    Thank you for the article on stapelias. I have a stapelia gigantea growing in the ground that had its best year ever – lots of flowers and lots of growth. Flies love it! However, huernia zebrina is not doing so well. Sun exposure seems to affect the color of the stems and I can’t tell if that’s a good thing or not. In the sun they’re orangey; in the shade they’re green and it hasn’t bloomed in several years. How much sun do you give yours? After reading your article I’m going to repot and try again.

    • Debra Lee Baldwin on November 5, 2022 at 6:38 pm

      Hi Nancy — I lost my Stapelia gigantea two years after I got it, which was really discouraging, but I’m ready to try again. My Huernia zebrina, on the other hand, is happy, although one stem has what might be the dreaded black rot. Hard to tell…it’s floppy and discolored. (Better get rid of it, I suppose.) As for where I keep the plant, it’s in bright shade most of the day with an hour or two of full sun. It’s crowded in its pot, and stems want to hang over the side and fall off, as though trying to escape. Those stems, which are new growth, are where flowers form, but tend to hide—they’re more in the shade than in the sun. I occasionally find fallen stems withered and beyond hope below the plant, which sits on a ledge.

  4. Karoline Brown on November 5, 2022 at 4:13 pm

    I have 3 of these stapeliads, all are in pots and kept inside. One has just finished 2 blooms and there is another stem with a bloom starting to show. The second one, blooms about 3 times a year and the last one does nothing bloom wise. Perhaps it is an older one and needs to be retired! I live in Henderson, NV in zone 9a…They did not do well outside, but enjoy the indoors.
    I follow your website and totally enjoy your videos, interviews and helpful hints.

    Thank you.
    Karoline

    • Debra Lee Baldwin on November 5, 2022 at 6:31 pm

      Hi Karoline — Good to know that you have stapeliads that bloom indoors. I got the impression from my research that they were too fiddly to grow in an indoor environment except a greenhouse.

  5. Horticat on November 5, 2022 at 4:43 pm

    Thanks for the article, Debra! I have a couple of these, but your photos of the more unusual varieties make me think I should get a few more to add to my collection. They are weird and wonderful!

    • Debra Lee Baldwin on November 5, 2022 at 6:28 pm

      Purr. I agree! I’m hoping to add a few more to my collection, too. The flowers are SO worth it!

  6. Nancy Mumpton on November 5, 2022 at 8:15 pm

    Our Central Arizona Cactus and Succulent Society PEG group met today and the topic was Stapeliads. Your post reinforces what the experts today told us even down to the best plants to try first! Thank you Debra for all you excellent information written with pictures of the plants. Fantastic!

    • Debra Lee Baldwin on November 7, 2022 at 11:37 am

      Nancy, wow, what a terrific comment and compliment! This makes me happy — thank you!

  7. Deva Brown on November 5, 2022 at 8:51 pm

    I have had stapeliads for many years and I love them, smell and all ! Here in S. Texas mine stay outside most of the year, just coming indoors for colder weather. I have 5 of the ones you mentioned in your article and would like to have more. Nice to see so many in one article. Thanks for the information.

    • Debra Lee Baldwin on November 7, 2022 at 11:36 am

      Hi Deva — Hopefully they’ll become more available. I’d love to have a larger collection, too.

  8. Alice Valentine on November 5, 2022 at 10:43 pm

    I really enjoy all of your articles. My mother-in-law gave me her large Stapelia gigantea (I think) and I keep it indoors – upstairs in a sunny NW facing window in the SF Bay Area. It gets a couple of blooms once a year. She recently died after 91 great years and I feel fortunate to have this succulent and a pencil cactus that she gave me years ago. I am going to try repotting it and fertilizing it to see if I can get it to bloom more often. Thanks for the tips!

    • Debra Lee Baldwin on November 7, 2022 at 11:36 am

      Hi Alice — What a wonderful reminder of your mother! May her plants continue to bring you joy.

  9. Kal Kaminer on November 18, 2022 at 11:00 am

    Stapeliads are my favorite succulent family! I grow well over 100 varieties. Most are easy to care for, and thrive in cultivation in a well draining soil. Thanks for posting this article!

    • Debra Lee Baldwin on November 19, 2022 at 11:44 am

      Thanks, Kal. You’re welcome! Wow, over 100 varieties? That’s amazing. You must have a greenhouse or live in an ideal climate.
