Q&A: What Causes Variegation?

I’m curious—what makes certain plants have variegated leaves? Is this an adaptation for survival, the way cactus features are or the way flowers are built to appeal to pollinators?

Answer: Variation in leaf color arises because of a lack of the green pigment chlorophyll in some of the plant cells. It isn’t an adaptation to the environment, but instead it is usually the result of a cell mutation, and can be inherited (genetic) or occur randomly (chimeric). If genetic, the color change is stable, which means that if you propagate a green shoot from a plant with colored leaves or sow its seed, the coloring will reappear in the new plant. This applies both to green leaves with irregular markings (variegation), say in white and yellow, and to those of a single solid color such as gold or purple.

A random mutation usually shows up as variegation. If you propagate from a green shoot or sow seed of the plant, the color will not recur. This kind of variegation is the most common, but is often difficult to stabilize. Propagation must be from variegated or colored shoots. In nature these forms usually die out, being weaker growers because of the lack of chlorophyll, which plants use to make the food they need for growth.

Variegation can also be the result of a viral infection, showing as discolored veins or leaf areas. This form of variegation is relatively rare, but it is stable. Lonicera japonica ‘Aureoreticulata’ has this type of variegation, with golden yellow veins netting the leaves.

Pictured: Lungworts (Pulmonaria) are plants more admired for their variegated foliage than for their flowers. This is Pulmonaria ‘Spilled Milk’.

Variegation
From Wikipedia, the free encyclopedia
This article is about variegation in botany. For histology, see Variegation (histology).

Variegation of fruits and wood in Ficus carica Panascè, a bicolor (yellow-green) common fig cultivar. This Italian cultivar is a chimera
Variegation is the appearance of differently coloured zones in the leaves, and sometimes the stems, of plants. This may be due to a number of causes. Some variegation is attractive and ornamental and gardeners tend to preserve these. The term is also sometimes used to refer to colour zonation in flowers, minerals, and the skin, fur, feathers or scales of animals.

Chimeral[edit]
Plants bearing such variegation are chimeras, with more than one type of genetic makeup in their tissues. A lack of chlorophyll producing tissue in some tissues causes variegation with white or yellow coloured zones on the leaf, contrasting with the usual green tissue. It is due to some of the plant’s meristematic tissue losing the ability to produce chloroplasts, so that the tissue it produces is no longer green.

In a common type of such variegation, the part of the meristem that produces epidermal tissue loses the ability to produce chloroplasts. The margins of leaves may be composed only of cells derived from this merismatic tissue. Hence, this marginal tissue is white or yellow, rather than green. There are several other types of such variegation, depending on the tissues that have been affected, and their relationship to each other. Variegation may be consistent and symmetric in appearance throughout the whole plant, or it may be quite random in location. In some plants, entire branches or stems including the leaves may be variegated. The variegation in some forms is unstable. The extent and nature of the variegation can vary, and sometimes the plant will return to the green form. In others it is stable and does not change under normal conditions and temperature.

Because the variegation is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation that preserves both types of tissue in relation to each other. Typically, stem cuttings, bud and stem grafting, and other propagation methods that results in growth from leaf axil buds will preserve variegation. Cuttings with complete variegation may be difficult if not impossible to propagate. Root cuttings will not usually preserve variegation, since the new stem tissue is derived from a particular tissue type within the root.

As these plants have some of their tissue unable to carry out photosynthesis, the plant will be weaker than the plain green plant. They should generally be expected to die out in nature and their only real source of survival is through cultivation.

Reflective[edit]

Variegation in holly leaves

Reflective variegation in Pilea cadierei.
Some variegation is due to visual effects due to reflection of light from the leaf surface. This can happen when an air layer is located just under the epidermis resulting in a white or silvery reflection. It is sometimes called blister variegation.

Pilea (aluminum plant) is an example of a house plant that shows this effect. Leaves of most Cyclamen species show such patterned variegation, varying between plants, but consistent within each plant.

Another type of reflective variegation is caused by hairs on parts of the leaf, which may be coloured differently from the leaf. This is found in various Begonia species and garden hybrids.

Sometimes venal variegation occurs – the veins of the leaf are picked out in white or yellow. This is due to lack of green tissue above the veins. It can be seen in some aroids.

The blessed milk thistle, Silybum marianum, is a plant in which another type of venal variegation occurs, but in this case it is due to a blister variegation occurring along the veins.

Pigmentary[edit]

Leaves of Red Clover (Trifolium pratense) have a typical v-shaped variegation.
A common cause of variegation is the masking of green pigment by other pigments, such as anthocyanins. This often extends to the whole leaf, causing it to be reddish or purplish. On some plants however, consistent zonal markings occur; such as on some clovers, bromeliads, certain Pelargonium and Oxalis species. On others, such as the commonly grown forms of Coleus, the variegation can vary widely within a population.

In Nymphaea lotus, the tiger lotus, leaf variegations appear under intense illumination.

Pathological[edit]
Virus infections may cause patterning to appear on the leaf surface. The patterning is often characteristic of the infection. Examples are the mosaic viruses, which produce a mosaic-type effect on the leaf surface or the citrus variegation virus (CVV). Hosta Virus X (HVX)[1] has caused such dramatic and attractive mosaic-type variegations that, when the disease was new to the United States, affected plants were mistakenly thought to be new mutations and were registered as new cultivars.[2]

While these diseases are usually serious enough that the gardener would not grow affected plants, there are a few affected plants that can survive indefinitely, and are attractive enough to be grown for ornament; e.g. some variegated Abutilon varieties.

Nutrient deficiency symptoms may cause a temporary or variable yellowing in specific zones on the leaf. Iron and magnesium deficiencies are common causes of this.

Nomenclature[edit]
By convention, the italicised term variegata as the second part of the Latin binomial name, indicates a species found in the wild with variegation (Aloe variegata). The much more common, non-italicised, inclusion of 'Variegata' as the third element of a name indicates a variegated cultivar of an unvariegated parent (Aucuba japonica 'Variegata'). However, not all variegated plants have this Latin tag, for instance many cultivars of Pelargonium have some zonal variegation in their leaves. Other types of variegation may be indicated, e.g. Daphne odora 'Aureomarginata' has yellow edging on its leaves.

Garden plants[edit]

Variegated plants have long been valued by gardeners, as the usually lighter-coloured variegation can 'lift' what would otherwise be blocks of solid green foliage. Many gardening societies have specialist variegated plants groups, such as the Hardy Plant Society's Variegated Plant Special Interest Group in the UK. Several gardening books which deal exclusively with variegated plants are available.

We had a White Jones (OJD's strain) that had 'albino' buds.

yes, she was a beauty, did you keep her?

Yep we did ;) When she shows her white stuff again, I'll post it again ;)

Cheers and thanks for liking! We'll do a blog post on the Albino buds in the near futur at our Academy. I'll post a link, no worries.

Cheers!

ive been running 2 strains.. that do this.. mainly like 1 side dark.. 1 side light.. I figure since the light side isn't growing as fast as the dark side.. that's the reason they kinda curve.. or look weird lol.. but I haven't seen any issues budwise.. growth seems normal.. and yield is still VERY NICE.. so I can say that so far.. I haven't really had any issues with this type of thing..

but ive also noticed.. that it varies in severity. with ph fluctuation .. a ph of 5.9-6 seems to keep it more darker green on both sides allowing for the leaves to grow more even...

atleast for my strains the ph is playing a huge role.. and mainly only shows a lot in veg.. once in flower it darkens up. so.. I just play with em till I find there sweet spot .. very weird shit.. but hasn't spread..

The ones that I've grown in the past and now don't show any leaf curving to the side of the variegation...but in the past I've also noticed variegation more so in veg and they seem to lose it in flowering mode, but some, like the ones this year have actually increased variegation in flowering

went and had a look at the variegated plants in the park yesterday.....some prick widened the path and I lost two more. There's just one left and it's the most variegated I've grown...this one should be ok as it is off to side of the (widened) track on the banks of a little stream

I'm not too concerned about that little blondie, but there's a 6 foot bushy plant that is 3 or so weeks away from finishing about 30 paces further on and I'm scared this big beauty will be cut...fingers crossed.

and it's not some local government contractor who is cutting a path through this 2 or 3 acre section of natural bush in this new park, it's some local guy who is doing it for phuck knows reasons. (maybe he likes getting bitten by mosquitoes?)

I've got some Super Silver Haze F3s that 50% of the females also show this veregation trait. The seeds were gifted so I don't have a clue about the parents used to make em.

They're really nice to look at.
 
here is one of the more interesting plants i have found while doing seed runs 501st notice not only the change in color but also the two blades on the left are fused or webbed

I see multiple mentions of SSH having variegation. This is a Super Lemon Haze seedling I popped. It is also growing faster than the other SLH seedlings (for now).

I've got a Blowfish F2 cut (my own selection) that likes to throw the occasional variegated branch.

I have the Chem D cut which shows it. Along with a Stardawg 91' plant that carries the trait. I also have the Sour Dubb cut. Which shows the trait in most people's gardens, but not in mine. Both times I have received the cut(got busted and got her back), she came with variegated leaves. After a month or so, it disappears and rarely shows up.

A lot of debate going on about variegated cannabis and mosaic virus. I have seen mosaic virus in tomato plants and they tend to go downhill rapidly with severely deformed leafs and slow growth. This does not seem to be the case with a lot of the variegated cannabis I've seen. This plant here just keeps going with no ill effects on growth rate or yield. Clones taken from the same mother plant will show different levels of variegation with some showing none at all.

^^^ interesting one there
that's the deepest yellow so far i think
the yellow bud, that's laying a claim for the most golden bud
