A jasmine is not always a jasmine...

Jasmine (Jasminum) is a wonderfully and strongly scented flowering plant in the olive family (Oleaceae) and its essential oil has been used for millenia as a perfume.  Jasmine flowers are usually white, have five to ten petals and always two stamens in each flower, and they are often hidden in a narrow corolla tube. The plants grow as viny shrubs.  Having only two stamens is a character that is consistent for all olive family members, like olive (of course), lilacs, fringe trees, and goldenbells - and jasmine.  A few jasmine mutant cultivars have filled flowers, so they have more petals of course.

The problem is that there is a similar genus, mock orange (Philadelphus), which also have white, 4-petaled flowers, and is gorgeously scented.  This commonly cultivated garden shrub is not in the olive family, but in the hydrangea family (Hydrangeaceae), and have lots and lots of stamens inside each flower. The stamens are the yellow 'fluff' in the center of each flower in the photo below.   In Swedish, the common name for mock orange is 'schersmin', and in English it is called 'false jasmine' obviously influenced by the true jasmine and similar scent and flower color.

So jasmine and mock orange are really easy to tell apart, and they are not closely related plants, but they still get mixed up over and over on food, cosmetics and other product labels.  True jasmine is commonly used in cosmetics and should be listed as various Jasminum extracts and oils on the ingredient label according to the INCI database. Philadelphus flower extract is also approved as an INCI-listed ingredient and used as skin conditioning agent, but it is not listed as 'jasmine' or similar in INCI. So generally speaking, if something smells nice and is called jasmine-something, then it should include Jasminum and have a picture of Jasminum on it, not Philadelphus.  Unfortunately, this is not always the case.

What really is scary is when the producers and sellers of the raw extracts and compounds don't know how to identify the images they use to promote their raw materials sold wholesale to other companies.  M K Exports India sells 'jasmine oil', and illustrates it with this inaccurate figure:

Here are some more examples of inaccuracies on labels and in advertising:

I also think the Rock Art Brewery's Jasmine Pale Ale Beer from Vermont has Jasminum in it, and not Philadelphus, but it is hard to know for sure. On the outside label is a Philadelphus flower.

Livestrong.com has a web page on the health benefits of jasmine tea, with a stock photo showing a tea cup with, you guessed it, Philadelphus flowers.

Some companies get it right, of course:

So, the two genera Philadelphus and Jasminus are really easy to tell apart even from small photos, but it is obvious that companies and photographers mixed them up.  Both are gorgeous garden or house plants, so it is well-worth to learn the difference between the two.

Canola oil flowers - four or five petals? Ask Trader Joe...

Canola oil is made from the rape seed plant's (several Brassica species) oil rich seeds, a member of the mustard family, the Brassicaceae.  Members of this family can easily be identified by their very typical flowers.  They have 4 petals, often white, yellow, or pink, situated in a cross-wise fashion, which gave them the old family name Cruciferae.  Yes, that is the same word beginning as in crucifix, a cross.

Brassicaceae flowers also have 6 stamens, and a central pistil that will develop into a fruit when/if pollinated.  All mustard plants have the same types of flowers, be it broccoli, garlic mustard, cabbage, arugula, or kohlrabi.  But there is one place, where the rule doesn't hold up...

On the Trader Joe's Canola Oil Spray bottle, sold only at the Trader Joe's supermarket, they have nicely added some flowers from the canola oil plant to the label. Only the flowers look like this:

So, what do we have here?  One flower with four petals (good!), and one flower with five petals (oops!).  And inside each flower, there are three 'things'.   I assume these might be stamens or pistils, but neither makes sense based on the numbers or shapes. The flowers are also never arranged in this particular fashion, but that is a minor point.

So, who cares? Well, if you make a piece of art you certainly can and should have artistic freedom. But, if you illustrate a product, the illustration should provide some knowledge (or excitement) or identification value about the product. It should be the real thing and not introduce errors or misunderstandings into the public's knowledge of plants and the product source.

The number of petals on mustard flowers are strictly determined by that group's bauplan, just like the 4 legs of a dog is based on a strict bauplan among allmammals. You don't go around and see a 5-legged dogs, do you? (5-legged dogs do exist, but are mutants, and they are even rarer in art.)

Here is the real canola:

So, in this case, the flowers on the label are used to illustrated the origin of a product, canola oil from the canola plant. There are no canola oil flowers with 5 petals. There are no canola oil flowers with 3 non-descript things in the center of the flowers.  If this drawing had been made with 4 petals it would have been equally pretty, and also accurate. So you start to wonder where things went wrong, with the illustrator, with the description to the illustrator, or to the designer of the label?
