Aspidistra elatior is such a well-liked houseplant that songs have been written about it, and in Victorian occasions anybody who was anybody had a minimum of one of their parlor.
However cast-iron crops are each bit as powerful, adaptable, and engaging when they’re grown open air within the backyard.
This species earned its widespread title as a result of they’re just about as powerful as forged iron. Tolerant and in a position to thrive in shade, drought, and depleted soil, there’s just about nothing that may destroy these strong specimens.
We hyperlink to distributors that will help you discover related merchandise. In case you purchase from one in every of our hyperlinks, we might earn a fee.
Hardy to USDA Zones 7 to 11, cast-iron crops carry life and coloration to boring, shady areas within the panorama.
They can be grown in containers in colder zones and introduced indoors for the winter.
In case you’re on the lookout for info about rising cast-iron crops indoors, learn our information.
In any other case, buckle in. Right here’s what we’re going to debate that will help you make your outside aspidistras thrive.
Indoors or out, rising cast-iron crops is a chunk of cake. However earlier than we wax poetic about how simple they’re to develop, you could be all for their origin story.
Let’s speak about that, first.
Cultivation and Historical past
Aspidistra eliator is indigenous to the southern islands of Japan and Taiwan. An herbaceous evergreen, it grows as much as three toes tall and vast within the understory of heat, tropical forests.
The lengthy, strappy leaves emerge from underground rhizomes and could also be stable inexperienced or or have quite a lot of patterns that includes stripes, spots, or each.
This species was first described by botanist John Bellenden Ker Gawler in 1822. It quickly gained not simply reputation however a real following, it was a bit just like the Pokemon of the late 1800s.
Victorians are well-known for his or her ardour for houseplants, and cast-iron crops had been probably the most sought-after within the mid-1800s.
Within the late nineteenth century, gasoline lighting was launched into Victorian houses and A. elatior had been among the many few houseplants that might survive the ethylene-heavy air that resulted from burning the gasoline.
Having an Aspidistra in these days symbolized a snug, middle-class life. However over time, it grew to become a logo of the pursuit of cash and standing, as George Orwell critiqued in his novel “Hold the Aspidistra Flying.”
As a backyard specimen, it’s by no means been fairly as widespread, however if you would like a plant that may enliven shady areas and gained’t be turned to lace by snails and slugs ( you, hostas), there’s no higher possibility.
In case your cast-iron plant is basically completely happy in its location, it should ship out funky purple flowers on the base.
The blooms have a perfume that’s earthy, type of like a mushroom, which is meant to draw fungus gnats (Cordyla sixi and Bradysia spp.) and slugs as pollinators.
Solid-Iron Plant Propagation
That aforementioned unusual methodology of pollination additionally implies that seeds aren’t available, so don’t fall for anybody promoting seeds on the market.
As an alternative, you’ll be able to both buy a plant or divide an present one.
By Division
If you have already got cast-iron crops in your panorama, propagation by division is simple.
Discover a healthy-looking clump of leaves with a pure division between them and observe them right down to the soil.
You’re going to want to dig this part out with a little bit of margin round it to make sure that you get chunk of the rhizome.
A. elatior has shallow roots, so that you don’t must dig very deep, however you need to dig good and vast. Use a trowel or spade and dig down a minimum of six inches.
All it takes is a little bit of roots and rhizome for the plant to outlive, however the extra you dig up, the higher. You possibly can both dig up the complete clump and separate it into a number of sections or just take away just a few stems with the rhizome and roots connected.
Upon getting your divisions you’ll be able to replant them as described beneath.
Transplanting
It is a plant that doesn’t endure a lot from transplant shock. As such, you don’t want any particular care to get your potted specimen or division into the bottom.
Dig a gap that’s twice as vast and simply as deep because the container the cast-iron plant is at present rising in, or within the case of divisions, a bit bigger than the foundation system. You need it to be on the identical degree it was within the container as soon as it’s within the floor.
Then, gently take away the plant from the container and loosen up the roots. Decrease it into the outlet, spreading out the roots. Fill in round with soil.
Add some water to the outlet and let the soil settle a bit. Add a bit extra soil if mandatory.
The right way to Develop Solid-Iron Vegetation
Solid-iron crops are so troublesome to kill that they’re featured in a brief horror story referred to as “The Man Who Hated Aspidistras” by William Fryer Harvey, a few man who was haunted by a cast-iron plant he couldn’t do away with.
The character in George Orwell’s novel, “Hold the Aspidistra Flying” tries to kill his specimen by burning it with cigarette butts, but it surely nonetheless gained’t die.
These crops have earned fairly a popularity for being indestructible. They aren’t fairly that powerful, but it surely’s not an exaggeration to say that they’re fairly resilient.
Something from partial solar to full shade is ok for aspidistras. Dappled shade or partial shade is right, however they may adapt.
Your cast-iron plant will in all probability even survive in full solar, however the leaves will seemingly find yourself burned, and so they gained’t develop as lush and delightful as they might in a extra hospitable location.
Solid-iron crops want persistently moist soil, although you’ll be able to let the floor of the soil dry out between waterings.
In case you water your backyard utilizing municipal water, remember that they’re a bit delicate to fluoride, so in case your municipality provides fluoride, contemplate amassing rainwater as an alternative.
They’ll tolerate excessive warmth, some drought, and depleted soil. They are going to even survive temperatures dipping right down to 18°F.
Ideally, give them unfastened, loamy soil, with a pH of 6.5 to 7.5, although the crops will tolerate some clay or sand. The one arduous and quick requirement is that the soil have to be well-draining.
Extremely variegated varieties with a lot of white or yellow on the foliage could be a little much less forgiving, nonetheless.
You possibly can preserve the plant in a gallon-sized or bigger container, although you’ll ultimately must improve to a three-gallon measurement. When you attain three gallons, preserve it in that measurement for the remainder of its life.
Use any clear, new potting soil that you simply want. Don’t reuse potting soil as a result of it could possibly turn into depleted or harbor pathogens. The one requirement is that the container has satisfactory drainage.

Scale
Fern scale (Pinnaspis aspidistrae) is probably the most typical pest to infest cast-iron crops. The grownup males are small and white, whereas the females are brown.
Each appear to be little bumps on the stems and undersides of the leaves, and so they typically seem on the highest floor of the foliage.
Scale bugs have a tough shell and use their sucking mouthparts to devour the sap from the plant.
This feeding causes yellowing and stippling of the foliage, and stunted progress.
They are often eliminated by gently scraping them off with a fingernail or butterknife and drowning them in soapy water.
You possibly can learn extra about scale bugs and how you can handle them in our information.
Spider Mites
Two-spotted spider mites (Tetranychus spp.) aren’t extraordinarily widespread, however they may feed on crops which can be dry or in scorching areas.

Get Cooking With Solid Iron… Vegetation
Even when they had been type of ugly, I’d in all probability nonetheless develop A. elatior.
They’re so easygoing and supply coloration and texture in areas that the majority different crops refuse to even contemplate rising.
They’re much more adaptable than hostas, and definitely harder, if you happen to can consider it!
