Hearts in Nature

January 28, 2019 By Lisa

How to find Hearts in Nature

Being able to improve observation skills begins with actually taking the time to look. We all love the Heart emoji, but lets free it from its smartphone home and see where it appears in natural form.

Ten places to find Hearts in Nature

  • Celandine

The humble Celandine has always been my favourite. The simple yellow 8 petalled flowers that spring up from a cluster of vivid green heart shaped foliage.

  • Cyclamen

The Cyclamen is similar with vein patterns against against the dark heart shape leaves.

  • Oxalis

Oxalis (you might think of it as a type of clover) comes in many forms, some are also known as false shamrock or wood sorrel. Many sport a triplet of hearts from the leaf stem. Displaying a pure love of rotational symmetry these triads of hearts are a close to perfect example of hearts in nature. Oxalis Triangularis displays the delicate indent at its peak. (If you’re thinking ‘Thats not a heart shape!’ read on to Cardiods)

  • Flamingo Lily

With heart shapes in both its flowers and leaves the Flamingo Lily is a brash statement of hearts in nature. The characteristic heart shape boasts the popular red colour too, but don’t be fooled, despite its emoji like appearance it can be poisonous.

  • Bleeding Hearts

Its name always puts me off slightly (elsewhere known as ‘Lady in a bath’ ) Bleeding Hearts are popular in cottage gardens where a row of heart shape flower buds hang from long flower stalk like bells.

  • Cockle shell

If you ever dig for cockles at the tide line, check out the heart outline created by its bilateral symmetry. We don’t often look at shells from this angle but here you can clearly see the heart shape outline and also the curves of the spiral forms that mirror each other.

  • Hosta

There are many varieties of Hosta which display heart shape leaves. Hosta are prized for the foliage as the flower spikes seem a little underwhelming. It’s the foliage everyone wants in their gardens and so many small and large types available, who wouldn’t want smoky blue hearts in your border?

  • Hoya

If you asked a child to draw a heart shape plant, the Hoya is what it might look like. Large heart shape succulent leaves and as an added bonus the flowers of the Hoya are perfect pentagonal star like blooms

  • Viola

Some see it as an invasive plant, but what is not to like about a profusion of hearts? Wild violet or Viola displays plain green small heart shaped foliage.

  • Helioptrope

Heliotrope, often seen on waste ground at roadsides clearly displays the cardioid shape.

Work your Cardio for Hearts in Nature

I know what you’re thinking: “Some are not really heart shaped, you can’t even see it clearly!”.

Well, it’s about form in movement and how you look at it. According to the Wolfram Maths Project there are ‘a number of mathematical curves that produced heart  shapes’ and we can see many of these as Hearts in Nature

Organic forms are forever growing and changing during their lifetime and this observation is about seeing the qualities of what makes a heart shape. Often they will change and morph to become more pointed or more ‘Cardiod’ during their lifetime.

Cardioid comes from the greek word for ‘heart’.

‘A heart shape curve, being the path of a point on the circle that rolls externally on another equal circle’.

See a cardioid being created as in the above definition in this animation from Wolfram Maths Project ( I love them!)

You can see in the illustrations above the variations of the cardioid heart curve.

Some of those plants above don’t look so strange now. Can you see any near you?
