Curio

Curio is for sunny windows and shallow pots where sculptural succulents can trail or stack without any tropical fuss. You will find string-of-pearls types, banana-like or bead-like trailers and upright blue-grey forms, all of them at their best with strong light and real dry-downs.

Curio feels playful, graphic and slightly arid without becoming bulky. In bright ledges, hanging spots and small containers, it adds a very particular kind of movement that looks sharper and cleaner than many softer tropical trailers. It suits homes that want something sculptural, light and low-volume.

Substrate help

Choose a faster-drying mineral-leaning setup

Succulents and many cacti need a mix that releases excess water quickly and keeps the root zone open, especially in indoor pots.

Curio

Quick Overview

Curio (string succulents) - high-light trailing care

Look: trailing succulent stems with bead-, banana- or finger-like leaves; well suited to sunny shelves and hanging pots.
Light: wants very bright light and usually several hours of sun to keep strings tight and compact.
Water: water thoroughly, then allow substrate to dry almost completely; roots rot easily in permanently damp, cool mix.
Substrate: best in sharply draining, mineral-heavy succulent mix; avoid water-holding peat-heavy composts.
Climate: tolerates dry air well; cold, wet roots below about 10 °C are far more dangerous than low humidity.
Toxicity: many Curio are considered mildly toxic if eaten; hang out of reach of pets and children.

Botanical Profile

Curio is an accepted genus in Asteraceae native to southern Africa. Many indoor Curio plants were formerly sold under Senecio, so the newer genus name helps distinguish the succulent, high-light species now placed in Curio.

Details & Care

Curio: trailing succulents like String of Pearls with a clean, graphic look

A bright spot and careful watering keep stems full

Curio covers several trailing succulents grown for bead‑like or banana‑shaped leaves and long, cascading stems. They suit hanging pots, shelves and narrow windowsills where light is strong.

Give bright light and allow the pot to dry well between waterings. Roots dislike staying cool and wet, while long dry spells can cause beads to shrink and drop.

Stems root easily at nodes, so a fuller pot is often just a matter of pinning a few strands onto the surface of fresh mix.

Light: Very bright light, with some sun if the plant is acclimated; weak light leads to sparse growth.
Watering: Soak the pot, drain fully, then wait until the mix is dry through most of its depth.
Pot choice: Shallow pots dry more evenly and reduce the risk of wet centres.
Signs: Wrinkled beads mean thirst or damaged roots; translucent, soft beads usually mean excess moisture.
Pests: Mealybugs can hide in leaf joints; inspect stems and treat early.

Frequently Asked Questions About Curio

Is Curio the same as Senecio?

In many shops, yes in practice, but not in current naming. Curio is an accepted genus, while many familiar trailing houseplants in this group are still sold under older Senecio names or under common names only.

Does Curio need direct sun?

Bright light is essential. Many common houseplant Curio cope well with some direct sun, especially string-of-pearls, banana, and tear types, but weak light is one of the fastest ways to get stretched, thin growth.

How often should I water Curio?

Wait until most or nearly all of the potting mix has dried, roughly 70–100%, before watering again. In winter, water very sparingly. These plants store water in their leaves and cope far better with short dry spells than with constantly damp mix.

Why is my Curio getting leggy or thin?

Almost always because the light is too weak. In dimmer conditions the stems stretch, the spaces between leaves get longer, and the plant loses the dense trailing look that makes it attractive in the first place.

Is Curio toxic to cats and dogs?

Treat common houseplant Curio as unsafe around pets. String of pearls, still often sold under an older Senecio name, is flagged as toxic if eaten, and the sap can also irritate.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)
