All About Growing Fenestraria Baby Toes

Fenestraria, also known as baby toes, are among the cutest succulents known. And they are super easy to grow — unless! Do not let the adorable appearance and common name deceive you into pampering this plant, or you’re sure to kill it quickly. By all means, tickle your baby toes, just don’t baby this tough little succulent, or you’ll be sorry! Read on to learn all the mysteries of growing Fenestraria.

Fenestraria

Fenestraria (Fenn-ess-TRAIR-ee-yah) is a monotypic genus — meaning it has just a single species. Fenestraria rhopalophylla, also known as baby toes or the baby toe succulent, is as tough as it is adorable. The name comes from the Latin word fenestra, meaning window. The name refers to the leaf windows at the tip of each leaf. In their native habitat of southeastern Namibia and South Africa, Fenestraria grow in full sun, buried deep in the desert sands with nothing but these translucent leaf window tips exposed. They look like a series of scattered glass marbles, don’t they? This remarkable adaptation enables the succulent to protect it’s leaves and stored water from the drying sun. Special cells allow sunlight to penetrate deep inside the plant where photosynthesis takes place. All lithops living stones and some varieties of Haworthia have leaf windows and similar growth strategies.

Growing buried deep like this is the plants’ response to the extreme conditions in their native climate. You should not plant your Fenestraria this deep. But do keep in mind how tough these baby toes are, so their cute appearance and tender name doesn’t lead you to kill them with kindness.


Fenestraria form clusters of pudgy, peg-shaped leaves, tipped by leaf windows. Essentially stemless, baby toes grow just 2.5″ (6.4 cm) tall in proper lighting. The roots are thick and fleshy, forming an extensive network to capture and make the most of any stray moisture in the soil.

Which is the ‘Real’ Baby Toes?

But which is the real baby toes?

Before we continue, let’s be sure we’re talking about the same baby toes succulent. Frithia is a different genus that looks remarkable like Fenestraria. So what’s the difference — and do you care? Both are evergreen, and just a couple inches tall. They look so much alike, but you’d better know the difference. Fenestraria are dormant in summer and actively growing and utilizing water in the winter. Frithia, commonly known as baby toes or fairy elephant feet (cute!), is dormant in the winter and actively growing in the summer. Each needs dry soil during their dormancy.

The easiest way to distinguish between Fenestratia and Frithia is their bloom color. Fenestraria have large, daisy-like blooms with long, slim petals in white or yellow. Frithia blooms are a bright, hot pink, though there are white blooming species. Frithia blooms are also shaped like a daisy, though the petals are shorter and wider. If your plant is not in bloom, take a good look at the leaf windows. Fenestraria leaf windows are far smoother, more round than those of Frithia, which are more ragged in their outline. Though Fenestraria are more popular, you can find Frithia available for sale.


Baby Toes Care

Water and Sunlight

Fenestraria baby toes are so easy to care for! Plant baby toes in fast-draining succulent soil. Give them a ton of sunshine and water rarely — only when the plant needs it. That’s it! 🙂 For the many (many) of you who have killed your baby toes with kindness — let’s go a little deeper.

Like all succulents, Fenestraria baby toes are well adapted to drought conditions. They store water for the plant’s later use. While they do need occasional watering, they are well-equipped to survive an absent gardener. It is too much water in the soil that is a threat to the plant’s survival. Because Fenestraria are more sensitive to over-watering than most succulents, let the plant demonstrate its need for water before you give it more. The leaves will become a bit wrinkled and slightly shrunken when the internal stores of water have been used. A good watering gives the plant what it needs and refills these stores. The “toes” swell and fill up plump again.


Over-watered Fenestraria split their leaves as they try to store more water than they can hold. This is a common cause of baby toes succulents dying. Fenestraria are dormant in the summer and should not be watered until they awake in the fall. If you follow the instructions above, you won’t have to watch the calendar to know when to withhold water and then when to resume. Jen White-Matthews’ healthy baby toes, above, display stress coloring — flushing light pink — due to growing in full sun. Thanks for the use of the photo, Jen!

Give Baby Toes Plenty of Light

Fenestraria baby toes are supposed to be short and pudgy — no more than 2.5 inches tall (6.4 cm). Likely, most you’ve seen were growing a god bit taller than that. When succulents don’t get as much sunlight as they need, they stretch, reaching for more light. This is called etiolation, and it can be deadly, especially for Fenestraria. Baby toes do not have a stem that can grow longer, bringing the leaves closer to the light source. Instead, the leaves themselves must stretch. When they stretch too far, they collapse — there is no longer a functioning path for water and nutrients to flow, and that part of the plant dies.

Most sites tell you Fenestraria can be grown indoors. While this is technically true, it assumes you have large windows with an unobstructed southern exposure that delivers a minimum of 6 hours of direct light each day. If you don’t, plan to grow your baby toes outdoors in direct sun for at least 5-6 hours a day or they will stretch. While they can tolerate a light touch of frost, plan to overwinter your baby toes indoors with a grow light for succulents  — unless you’re in a frost-free climate.

Propagating Fenestraria

Like lithops living stones, Fenestraria are members of the Aizoacaea family. Succulent members of this family that resemble stones were formerly classified members of the Mesembryanthemaceae family, and are still called mesembs. Because baby toes, like other mesembs, have no true stems, the only way to propagate these little charmers is via succulent division or by sowing seeds. Fenestraria form offsets that can be divided from the main plant to be potted separately. In the photo above, can you see that the baby toes near the front right can likely be divided from those front left and both sets from those in the back? Because they are slow to grow from seed, division is the best way to propagate baby toes — at least for those impatient sorts like me! 🙂 However, the seeds are tough and long-lived, so you can readily find viable Fenestraria seeds from reputable sellers.


The photo above, by Dr. Megan Yap, shows off the Fenestraria well, making great use of a soil top dressing. Dr. Yap is a noted paediatrician and writes Kids Health Guru. How fitting that her baby toes are thriving!

Shopping for Fenestraria Baby Toes

I’m not sure why, but I seldom find Fenestraria plants at my local nursery or box store. But they’re easy to find online — just be sure to select a reputable succulent vendor. Mountain Crest Gardens, Leaf & Clay and The Succulent Source all offer baby toes as potted plants. Each of these companies consistently delivers top quality plants. You’ll also find both Fenestraria seeds and growing plants available from good vendors on Amazon. I hope you’ll choose to grow this charming little plant!

Just be sure never to baby your baby toes!

    Thank you. Would love to have some but I don’t get good sunlight. I would grow them indoors.

      Hi Joan,
      Then I would recommend you check out Lithops – another mesemb, but one that is happy indoors! 🙂

    Hi Kat
    I have a small Fenestraria Baby Toes that I have had for several months now. When I bought it it had about 5 ‘leaves’ a couple of which were split.
    I repotted it into a terracotta pot with very well draining mix and it appears to be happy over winter (I am in South Australia) giving me lots of new little ‘toes’.
    It is outdoors in a very protected position under the eaves facing North where it gets any available sun (which is very little lately) but no rain. I have not watered it for months but on close inspection it does look a bit shrivelled ….. how can I tell when to actually water it?
    We still have the potential for some cold days ( max low teens centigrade) but never freezing or frost, for the next couple of months.
    I have photos but couldn’t figure out how to attach them to this comment.
    Always enjoy your blogs ????
    Best wishes

      Hi Lea,
      Please feel free to email me your photos – I will be happy to take a look! 🙂 Kat@TheSucculentEclectic.com
      The first thing to look for when deciding when/of to water the fenestraria is for a bit of wrinkling in the leaves which demonstrates that the water storage cells are no longer full. You have that. But then look to be sure the plant is actively awake and utilizing its resources. Fenestraria baby toes are dormant in summer, and it sounds like you are in your winter season, yes? So they are actively using water and the wrinkling says they could take more. Water well, until the water comes out the drainage holes. The toes will plump up and the plant will be happy for weeks at the temps you descrobe. When the plant next needs water, you’ll see the toes start to wrinkle again! 🙂
      Thanks SO much for reading!

    Hi Kat, I have a question about the blooms. Are we supposed to prune them or do they shrink away on their own when done blooming? I’ve been looking for the answer, but no one seems to talk about it. Thanks Karla

    1. Kat McCarthy

      Hi Karla,
      If your Fenestraria plant is really small, and you are eager for it to grow more quickly, snip off the bloom stem while it is still in bud. That way, the plant focuses it’s energies into more plant growth. If you are happy to see the bloom, allow it to flower and enjoy! 🙂 Once the flower is spent, snip off the stem to keep the plant looking tody. Take care not to cut into the leaves when you cut the stem.
      Enjoy your baby toes!

    Hi Kat,
    Thank you. I hadn’t tried the baby toes plant & just received them a couple weeks ago. The buds didn’t make it through the shipping, but didn’t know what to do & didn’t want to kill the plant by cutting something I shouldn’t. Glad I found your place as I’m enjoying reading all the Q&A. Karla

      Hi Karla,
      So glad you’re finding it helpful!
      Any time I can answer a question for you – just let me know! 🙂
