When you take a deep dive into the world of succulents, you shortly uncover how extremely diversified and interesting these vegetation might be.
One explicit curiosity you’ll discover is that some species flower and fruit simply as soon as, after which they die.
When you’ve ever grown a kalanchoe that bloomed superbly after which died, then you definately’ve encountered a monocarpic plant.
It’s value investigating whether or not a succulent is monocarpic earlier than you add it to your assortment, as a result of this information can change your rising plans or methods.
Plus, you received’t be shocked in case your succulent appeared completely wholesome and after blossoming it dropped useless.
On this information, we’ll clarify what monocarpism is and which succulents fall into this class. Right here’s the listing of species we’ll go over:
Earlier than we have a look at the listing, let’s make clear some phrases.
The phrase “monocarpic” might be damaged down into two: mono and carpic. In Greek, mono interprets to 1 or single and karpos means fruit.
That doesn’t imply the plant solely produces one flower, it refers to these species that flower only one time after which the lifecycle ends.
Some gardeners name this the “dying bloom,” which I believe is a time period that needs to be accompanied by a deep voice and scary music.
Monocarpic vegetation are additionally known as suicidally reproductive or, incorrectly, hapaxanthic or semelparous.
These latter two phrases technically discuss with species which have stems that die after flowering, not your complete plant.
A real monocarpic plant comes from a single zygote and your complete plant dies after it blooms. If a species solely dies again partially, or new development emerges from the roots, it’s not monocarpic.
Why does this occur? To grasp it, we have to do a quick lesson in botany. All vegetation have apical meristems, that are specialised teams of cells chargeable for development.
In monocarpic succulents, the apical meristems produce vegetative development all through the plant’s life.
Then, because it reaches maturity, the apical meristems change and begin producing the flower stem, or inflorescence.
This swap from vegetative development to flower manufacturing is irreversible, so the apical meristems can not produce leaves, so when the flower fades and seeds are produced, the succulent dies.
Monocarpic succulents sometimes ship out pups or plantlets, that are genetic clones, earlier than they die. These plantlets develop their very own root system and develop independently of the father or mother.
Some succulents are erroneously regarded as monocarpic. Echeveria, most crassula, peperomia, and sedum are all polycarpic.
Let’s check out 9 monocarpic succulents in additional element:
1. Aeonium
Most tree houseleeks (Aeonium spp.) are monocarpic, however not all. These with a rosette the place a single flower stalk emerges from the middle are possible the sort that flower as soon as and die.
Actually, simply assume that yours is monocarpic until you study in any other case. These with a number of stalks or pinwheel-like development are possible not.
The identify “Aeonium” comes from the traditional Greek phrase aiōnios, which suggests ageless.
This can be a nod to the truth that they don’t appear to die. As an alternative, they ship out plantlet clones that proceed their lifecycle. The unique specimen would possibly die, however the clones carry on going.
Most come from the Canary Islands, however they’ve turn into common backyard vegetation in Zones 9 to 11 and houseplants world wide.
2. Agave
Agave is the genus that provides us tequila, syrup, and maintenance-free ornamentals for USDA Rising Zones 7 to 12, relying on the species.
These succulents are sometimes gradual rising with thick, slender leaves and originated within the Americas, although you’ll discover them throughout the globe.
Not all Agave species are monocarpic. Actually, most are polycarpic, however they’ve sections that flower and die, which may trigger some confusion amongst gardeners.
In fact, the well-known century plant (A. americana) flowers as soon as after many years of development after which dies. If I needed to guess, this might be one of many extra well-known monocarpic agaves.
Palmer’s agave (A. palmeri), Caribbean agave (A. angustifolia), foxtail (A. attenuata), dolphin agave (A. guiengola), and blue (A. tequilana) are all monocarpic.
A straightforward, although not completely foolproof, approach to inform if an agave is monocarpic is to take a look at its development behavior. If the leaves emerge from a central basal rosette, it’s prone to be monocarpic.
Plant taxonomy is continually altering. Simply while you suppose you realize the place a species suits within the classification system it modifications.
Manfreda is one such genus. Some consultants classify the species on this genus as Polianthes, and others stick it in Agave. Proper now, most are categorized within the Agave genus.
No matter you name them, not many Manfreda species are monocarpic, however just a few are. Use the identical pointers in figuring out their development sample as you’ll with agave.
You possibly can study extra about agave in our information.
3. Aichryson
Aichryson is a genus of understory succulents indigenous to the Canary Islands, the Azores, and Morocco.
They aren’t almost as common in cultivation as their Aeoium and Sempervivum cousins.
That’s partially as a result of they’re solely hardy in Zones 9 to 11 and in contrast to many succulents, they like moist soil and funky circumstances.
However Aichryson species make wonderful houseplants and gardeners in areas just like the Pacific Northwest, mid-Atlantic, or Pacific Coast ought to positively give them an opportunity.
This genus includes two sections: Aichryson and Macrobia. Sect. Macrobia solely consists of the species gouty houseleek (A. tortuosum), which is a polycarpic perennial unusual in cultivation.
The entire different species within the genus belong to sect. Aichyrson and these are all monocarpic.
They’ll fill in shaded areas however will adapt to full solar, they usually’ll add brilliant shade with their neon yellow blossoms.
4. False Agave
Species within the Furcraea genus, generally often known as false agave, are all monocarpic they usually’re not afraid to point out it.
After they lastly type, the flower stalks might be 40 toes tall or extra. Mauritius hemp (F. foetida), for instance, grows just some toes tall however the flower stalk is 25 toes tall.
These succulents originated in Mexico, Central America, northern South America, and the Caribbean, however they’ve naturalized in heat areas of North America, Africa, Australia, and India.
They are often cultivated in Zones 8 to 12, relying on the species.
The vegetation on this genus look loads like agave, as you may need guessed. Botanists inform the 2 aside by wanting on the flowers.
Agaves have bell-shaped blooms the place Furcraea flowers are bulbous. To the house gardener, it’s fairly troublesome to inform the 2 aside.
5. Jovibarba
Many botanists contemplate Jovibarba to be a defunct genus, with the three species previously categorized as Jovibarba reclassified as Sempervivum.
I’m mentioning this former genus individually as a result of Job’s beard or Jupiter’s beard, as these vegetation are generally identified, are sometimes nonetheless known as Jovibarba.
All of those are monocarpic, sending out tubular, bell-shaped blooms earlier than they die. However they don’t reproduce like a number of the different species on this listing.
As an alternative, S. hueffelii kinds pups inside the mom plant. They don’t emerge until you chop the plant open with a knife to show them otherwise you let the mom die after flowering.
On S. globifera and S. hirta, little offsets develop that detach from the father or mother and roll away. That’s why these two species are sometimes referred to as “rollers.”
These succulents develop in Zones 5 to 11, and are indigenous to the mountains of southeastern Europe.
6. Kalanchoe
Some, however not all, Kalanchoe species are monocarpic.
The usually confused flapjacks Ok. luciae and Ok. thyrsiflora, together with mom of hundreds (Ok. daigremontiana) flower as soon as and die.
Many hybrids like ‘Pink Butterflies’ and alligator plant (Ok. × houghtonii) are additionally monocarpic.
It may be laborious to inform by taking a look at a specimen if it’s a monocarpic one or not, but when the leaves develop out of a single important stem, the species is probably going monocarpic.
However this doesn’t at all times apply, so that you’ll must analysis the precise species or hybrid if you could know for positive.
Most are indigenous to Madagascar and Africa, however they’ve naturalized in lots of components of the world and are common as houseplants and backyard vegetation.
Our information to rising kalanchoes has extra info.
7. Orostachys
Orostachys is a genus of succulents usually mistaken for echeveria, sedums, or hens and chicks.
These vegetation originated in Asia and Russia, and thrive in comparatively cool climates from Zones 4a to 9a. They’ve small clusters of pink and white flowers that seem in the course of the summer time or fall.
Most species on this genus are polycarpic and the flowers will seem yr after yr, however there are just a few exceptions.
Chinese language dunce caps (O. boehmeri, O. iwarenge, and O. furusei), rock pine (O. japonica), and spiny pennywort (O. spinosa) bloom as soon as after which die.
The unusual O. malacophylla var. malacophylla, O. maximowiczii, and O. gorovoii are monocarpic as properly.
Orostachys species are likely to shortly type dense clumps of rosettes, so when one blooms and dies, it’s hardly noticeable among the many dozens of remaining rosettes.
8. Sempervivum
It ought to come as no shock that Sempervivum species are monocarpic.
“Semper” means “at all times” and “vivus” means “life” in Latin. So these succulents reside ceaselessly. Or, a minimum of, they’ve the power to repeatedly put out new vegetation to switch those that die.
Hens and chicks can have some beautiful blossoms. However once they seem, it implies that the plant is nearing the tip of its life.
That is true of all species on this genus. Thank goodness they ship out so many little “chicks” to switch the dying father or mother.
In fact, these aren’t truly chicks, neither is the principle plant a hen. On the earth of botany, the chicks are often known as offsets. They type on lengthy horizontal stems referred to as stolons.
The newly forming plant finds a spot within the soil, settles in, and develops roots. When it has roots in place, the stolon dies and the offset is now a plant in its personal proper. These offsets are clones of the father or mother.
Because the plant matures, it will definitely develops star-shaped flowers in pink, purple, yellow, or white.
These flowers give approach to fruits with seeds, after which the plant dies. Some species reside just a few years, and a few reside a decade or extra. You could find choices for Zones 3 to 11.

9. Yucca
The overwhelming majority of Yucca and Hesperoyucca species are polycarpic, however just a few aren’t.
Among the many monocarpic species, chaparral yucca (Y. whipplei syn. Hesperoyucca whipplei) grows a beautiful ten-foot-tall flower stalk with a whole bunch of white, pink, or purple bell-shaped flowers.
Adam’s needle yucca (Y. filamentosa) has shorter, much less showy inflorescences.
Newberry’s yucca (H. newberryi) is monocarpic and peninsular candle (H. peninsularis) might be both mono- or polycarpic, relying on the plant and the setting.
What’s with the 2 genera, you is likely to be asking. Hesperoyucca is a genus of simply three species had been previously categorized as Yucca and largely, they’re nonetheless referred to as yuccas.
To the house grower, they’re indistinguishable. In actuality, even botanists don’t agree on how the vegetation in these two genera needs to be categorized.
The classification of chaparral yucca, for instance, remains to be a sizzling matter of debate.

I can’t inform you what number of occasions somebody has complained about dropping a favourite succulent and assumed they’d finished one thing incorrect.
It’s simply the character of some succulents to bloom as soon as after which die.
