Friday Flower – Pineapple

Yes it is true that the pineapple is a fruit, but did you know that to make a pineapple, this bromeliad must flower. Actually the flower spike it produces is up to 6 inches (15cms) tall, and will contain up to 200 spirally arranged flowers. The fruits (technically they are berries) develop from the ovaries of the individual flowers, which then join together to become the yummy pineapple that we eat. The fruits are arranged into two interlocking helices, one containing 8, and the other direction containing 13. These numbers are both Fibonacci numbers. I don’t want to bore you with too much mathematics, but the sequence goes as follows, 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55…and so on. Each number is the sum of the two preceding numbers. Fibonacci numbers often appear in nature (which is governed by mathematics) such as in the branching of trees, arrangement of leaves along a stem and in succulents, petals on a flower, pine cone bracts, the list is huge. So those of you that love nature, and never thought of yourselves as mathematicians, you are actually math admirers.

Have a great weekend everyone!

Flower Friday – Dragon Fruit

Todays post includes some photos taken by my dad of one of the plants he is currently growing in his garden at home. Pitahaya (more commonly known as dragon fruit) are the edible fruits which grow on several species of cactus. The particular fruit in this photo are from the species Hylocereus undatus which are red fruits with edible white flesh on the inside. The flowers of this cactus (which are in the photo below) are a brilliant white, very large and fragrant. They open mostly in the evening due to their main pollinators such as bats and moths being nocturnal, although my dad said these opened during the day and only lasted a day or so, possibly a difference in climate from their country of origin. If you’d like to see more photos from my dads garden or the gardens he looks after (as he is an amazing and truly talented gardener) you can visit his Instagram page @salvenut.

Happy weekend everyone!
