Like all snake plants, the Hahnii is tough and an excellent choice for beginner gardeners. Like all members of this plant family, the leaves are mildly toxic to humans and pets if chewed. The plant juice can also cause a skin reaction, so wear gloves when re-potting or pruning your Hahnii.

It never grows taller than 12 inches, but its densely packed, short leaves make it a solid choice for small pots and feature areas. The greeny-yellow pattern makes Sansevieria Hahnii a manageable yet visually appealing plant.

Interestingly, the Hahnii variety originated in a nursery environment in 1939 from Sansevieria Trifasciata, so it does not occur anywhere naturally. The Trifasciata, or snake plant as it is commonly called, is native to West Africa.

Hahnii is known for its tightly packed, attractive foliage, but it may occasionally also produce flowers. This rare occurrence only happens during the summer months when white flowers tinged with green may be produced. The flowers have a sweet scent.

Like all snake plants, it does well in many settings and has the added benefit of filtering airborne toxins from indoor spaces. It is also tolerant of artificial light, which makes it ideal for office settings.

Keeping your Hahnii plant looking healthy is simple. It is a hardy little plant that requires very little care. However, it is not indestructible, and there are some elements that you should be aware of to keep your Sansevieria Hahnii in perfect condition.

Sansevieria Hahnii Light Requirements

One of the very best things about snake plants is that they are tolerant of most lighting conditions. While it isn’t recommended, they can even adapt to low light or full sun conditions with time.

Hahnii grows best in bright indirect light. Like most succulents, they thrive on light, and for optimal growth or even the occasional bloom, this variety should get at least 6 hours of bright light each day.

Interestingly, unlike many other pot plants, Hahnii is not fussy about the source of the light. This makes these plants ideal for offices where there are fluorescent lights.  They do not do well and may become stunted if they are kept in very low light conditions.

Sansevieria Hahnii Temperature Requirements

Snake plants have their origins in West Africa, so they are not tolerant of extreme cold. The best temperature to keep Hahnii healthy is between 60-85F.

While they can survive short periods slightly below 60F, they are not as cold-hardy as many other house plants. You will see browning on the leaves and general deterioration in their condition if they are exposed to temperatures below 50F.

Sansevieria Hahnii Humidity

The recommended humidity level for Hahnii is between 40-50%. However, it is better to err on the side of drier air than to mist it and allow large water particles to collect on the large, succulent leaves.

The biggest enemy of Hahnii is root rot, so if you suspect that the environment for your plant is too dry, it is better to provide a pebble tray or group it with some other plants rather than misting its leaves.

Sansevieria Hahnii Soil Requirements

Soil mix

The most important thing about Sanserviera Hahnii’s soil is that it must be free draining. Any standard succulent or cactus soil mix will work perfectly. You will also get good results if you mix it in equal parts with regular potting soil, but it must contain some course elements like gravel and sand so that moisture is never trapped around the plant’s roots.   

Re-potting and refreshing the soil is not often required, and many growers leave their Hahnii’s in the same container for up to five years. However, it is good to add soil or loosen the soil in the pot at least every year so that it does not become compacted around the plant’s roots.

The container that you are keeping your Hahnii in is equally, if not more important than the soil mix. The bottom must have holes to allow water to flow through freely. Water must at no time build up around the plant’s roots because overwatering is one of the surest ways to kill a snake plant.

The chance of loving your plant to death by giving it too much water may be somewhat reduced if the soil and the pot allow excess moisture to drain through.

Watering The Sansevieria Hahnii

 Sansevieria Hahnii is so cute that you want it to thrive, but watering it too often will do more harm than good. These plants are drought-tolerant succulents which means that they store water and can survive dry spells.

Before you reach for a watering can stick your index finger into the soil and if you feel any dampness, hold off until the soil is completely dry. Instead, let the plant become too dry than possibly drown its roots.

When you water the Hahnii, use a can that can direct the water onto the soil. Avoid pouring water onto the leaves as it can build up at the spiral base of the plant and cause rot and brown patches.

Ensure that the holes on the base of the plant’s container are fully open to allow excess water to move through the soil quickly. Also, check that the saucer that the plant is standing on is dry. If your Hahnii is in a small container, you can even lift the container so that excess water can completely escape while you are adding water.

The frequency that you need to water a Hahnii depends on the temperature. In general, it shouldn’t need to be watered more than once a week, even in mid-summer. During winter, this can be decreased to once a month.

Occasionally the leaves may become dull or look dusty. Do not be tempted to wash them off using a lot of water. Leaves can be cleaned by wiping them with a damp cloth.

Sansevieria Hahnii Fertilizer Requirements

Fertilizers should be applied sparingly to Hahnii plants. They are low-maintenance succulents, and when fertilizer is provided, it must be diluted to half the recommended strength. A general-purpose fertilizer is fine for Hahnii if given in a very weak concentration once a month.

Propagation Of Sansevieria Hahnii

Once you have your Hahnii growing well, you will be able to propagate plenty more to share with colleagues and friends. The two methods to easily propagate new plants are leaf-cuttings and division of the root ball.

1. Propagation By Root Division

Root division is by far the most successful and easiest method. If your Hahnii begins to form multiple rosettes, you can simply divide off any additional rosettes and plant them directly into another pot. Be sure to divide the pup from the original plant cleanly.

The plant will spread naturally through rhizomes that push up in all directions around the original plant in outside conditions. You can divide the plant’s root ball into sizable chunks and plant each piece into a new pot if you are re-potting.

2. Propagation By Stem Cuttings

If you have a healthy Sansevieria Hahnii plant, you can carefully snip a large leaf at its base. The leaf should then be left to dry out for at least two days before planting it into its own pot. It might take a few months before the cutting develops roots, and during this time, the soil should be kept slightly damper than you would an adult plant, but it must never be soggy.

When you plant the leaf, be sure that it is the right way up! Many frustrated growers have discovered too late that they accidentally planted the leaf tip instead of the base.

Diseases and Pests That Affect Sansevieria Hahnii

Aphids and pests
Insect pests, aphid, on the shoots and fruits of plants, Spider mite on flowers. Pepper attacked by malicious insects.

By far, the deadliest problem that might affect the health of all snake plants is root rot as a result of overwatering. This is easily avoided by letting the soil dry out completely before giving water.

If your Sansevieria Hahnii has developed root rot, you can try to re-pot it. Cut away as much of the damaged, mushy root as possible and plant it in clean soil. It might not be possible to save it, but re-potting it as soon as you notice the condition is the best option to save it.

Plant pests do not often affect Hahnii. However, like all other houseplants, they can occasionally be infested with spider mites, mealybugs, or aphids. Plant insecticides or neem oil work well to treat these common plant pests.

Conclusion

Sansevieria Hahnii is a gorgeous miniature variation of the ever-popular snake plant. This plant offers all the hardiness and patterned beauty of the common lanky variety but grows in a spiral formation from a central point. It is perfect as a pot plant in the home and ideal for office environments where space might be limited.
