This very popular houseplant often goes by the name Corn Plant, or by its official Latin name of Dracaena fragrans (impossible to say without sounding French!), it may also be known as Dracaena massangeana. The genus has several other well-known members that we invite happily into our homes, such as Dracaena marginata and Dracaena sanderiana all of which are reasonably content to share our living or office space without a lot of fuss.
In return for a little bit of care and attention from time to time, the Corn Plant will show off its shiny good looking leaves and removal various indoor air toxins. If you treat it very well, after many years you should get a bold ascent specimen with multiple crowns and the opportunity for it to produce a small spray of fragrant white flowers. Simply beautiful with minimum effort.
It will come either attached and sprouting from a brown textured stem, more correctly known as a Ti Tree, (much like a Yucca does) or the stem will still be "alive" green and resemble that of the Lucky Bamboo. Either type is suitable for the home so pick the style you like best. In shops you will tend to find one of four popular varieties and cultivars for sale. Again just pick your favorite as they all need the same general care requirements and are all quite easy going.
The original, with solid green leaves. The original is the least common and of course, it will have its fans but the variegated versions outsell this one massively.
D. fragrans 'massangeana'
By far this is the most commonly found and bestselling Corn Plant cultivar. Distinctive with its sold corn yellow like stripe that runs through the center of each and every leaf means it's easy to see why it is so sought out and why so many people just call this plant Dracaena massangeana and drop the "fragrans". In comparison to the other variegated ones, it tends to have a thinner yellow line and is less distinctive than D. fragrans 'victoria' (see below). The leaves overall also tend to be narrower and longer.
D. fragrans 'lindenii'
This time, the corn yellow is found on the edges of the leaves rather than through the center, which makes it easy to confuse with another houseplant called Dracaena reflexa 'variegata' or the Song of India. The Song of India however is not overly popular as a houseplant (which is why you won't find a profile for it on Ourhouseplants.com) but if you are a fan of the colorings, do try and seek out D. fragrans 'lindenii' instead.
D. fragrans 'victoria' or 'victoriae'
Very similar to 'massangeana' in that the yellow stripe runs through the middle of the leaf, however it tends to have smaller but wider and almost triangular leaves. The Yellow corn stripe is also bolder and more distinctive. Overall this cultivar is probably the most attractive out of the four mentioned here, not just because of the yellow stripe but also the leaf shape is neater and more compact. However it does not grow quite as fast and commercially it can be a pain to find.
Most of those in the Dracaena genus including the Corn Plant do best in light shade or gentle filtered sunlight. The leaves will scorch if too bright and if it's too dark the new leaves will be quite small and the stripe(s) may look quite different to those found on the older ones.
These plants benefit from a little "drying time" between waterings. So water well and then wait for the top inch of the soil to dry out before watering again. If your Corn Plant is placed in a good spot with reasonable light and warm temperatures, (excluding Winter) you can keep the soil moist at all times. Regardless of your placement, in Winter reduce the watering like you would for almost all houseplants, but the soil shouldn't be allowed to dry out completely.
Reasonable humidity is required to prevent blemishes on the Corn Plant's leaves. Misting is a good way to achieve this as well as helping to keep the leaves dust free.
Regular feeding in Spring and Summer is recommended. You don't need to feed in Winter or feed newly repotted plants.
The Ideal growth range is between 16°C - 24°C / 60°F - 75°F. No lower than 10°C / 50°F and avoid even light frosts at all costs.
You only need to really repot every two or three years. But there is no harm in doing it more frequently if you feel it's needed and of course if you have the space and a big enough pot for it.
There are three main ways to propagate and typically you can do all three methods at once to create multiple plants. In time the canes will become leggy as the leaf area shifts higher and higher up the plant which means you can:
Speed of Growth
It's quite slow growing, but there is enough new growth to notice its "alive" and draw attention to itself (that might sound wacky, but seasoned indoor plant owners will know what we mean).
Height / Spread
This depends on how tall your ceiling is! To be fair, while natively it could reach 15m / 49ft or more, indoors you will probably run out of large enough pots to allow the plant to ever reach such a size, so expect it to only reach 2m / 6ft after many years.
You rarely find flowers on indoor plants from the Dracaena genus, D. fragrans though is the exception. Pay attention when we say the flowers are still not frequent enough to call their appearance "common", but they do occur occasionally if the plant is mature and being treated well. Sprays of small numerous white flowers will come shooting out of the crown and they have a highly fragrant almost sickly sweet scent.
Are Corn Plants Poisonous?
The sap found within the leaves and stems do have small levels of a toxic substance that, while unlikely to be fatal, can cause irritation in people and pets when eaten.
In most cases if you end up with flowers you are very lucky. You'll need a mature, well cared for plant that is basically happy. Even then, the flowering is unpredictable and does not occur every year or with any sort of pattern.
Yellow lower leaves / leaf drop
All Dracaenas including the Corn Plant are False Palms, with a crown of leaves sitting at the top of their stems, new growth forms at the very tips of these stems and the older leaves at the bottom of the crown will gradually yellow and fall. This happens quite often, but providing new leaves are forming as well it's normal.
Leaves with brown spots
Normally this is a sign of underwatering. You must try to keep the soil moist at all times where possible because although the plant will cope with periods of occasional dryness, if it's prolonged then damage will result. If the brown spots are are more "blotches" than dots, it's caused by overwatering. The plant in the photo shows brown spots as well as the next problem:
Bleached dry leaves
Scorched leaves caused by too much sun. Move to a more shadier area.
Leaves have brown tips and yellow edges
This is often caused by dry air or cold draughts. Increase humidity and keep warmer.
Soggy Cane / Stem
Too much water over a long period, usually when it's also cold. If this happens then your Dracaena is probably already on its way out and can't be saved in its present form. Although if any parts of the stem feel firm, or the leaf crown is intact you could try and propagate.
