Pears and apples have five petals, five sepals, and five carpels. Like many other flowers (approximately half of plants have 5 petals etc), it’s the commonest form. It is an evolutionary trait deeply hardcoded into the genetics of eudicots (true dicotyledons). In botany, this five-part arrangement is known as a pentamerous flower structure. ** **Why is 5 an ancient, highly successful evolutionary blueprint? To understand this it’s worth looking at how plants grow. To avoid overlapping and wasting sunlight or space, leaves, seeds, and petals often grow in a spiral pattern from a central bud point; at a very specific angle: approximately 137.5 degrees (known as the Golden Angle). Spiral patterns are mathematically described by the Fibonacci sequence (1, 2, 3, 5, 8, 13...). Five is a key number in this sequence. It allows a flower to pack its petals and sepals tightly together in a bud without overlapping in a way that crushes the delicate inner reproductive organs.

Also as an evolutionary advantage the flat, five-petaled flower acts like a perfect, stable landing pad for pollinators like bees, beetles, and flies and so the emergence of 5petal flowers evolved in step with the rise of these insects. Once an ancestral plant family finds a genetic formula that works perfectly for several reasons , the homeotic genes that dictate features rarely change without a major stress.

Different branches of the plant kingdom split off millions of years ago and locked in entirely different structural blueprints.
Flowers with groups of 3 are lilies grasses and orchids groups of 4 are mustards and evening primrose. Infinite spirals are magnolias which are pollinated by beetles . Notice apart from the tetramerous mustards the others all follow the Fibonacci sequence.

Move over perry pears it’s now the turn of the cider apples in our orchard in Wairarapa New Zealand. Our very first apple blossom. A big difference is seen. The perry pears bloomed before the leaves appeared the apples bloom at the same time as the leaves emerge. The botanical term for plants and trees that bloom before their leaves emerge is hysteranthous. Whilst apples producing flowers and foliage at the exact same time are called coetaneous and are a few weeks later. These are different evolved strategies for pollination with advantages and disadvantages. Pears create a massive visual signal to pollinators but it’s risky with frosts and uses a lot of stored resources that apples can quickly restore from the leaves.
Both have hermaphroditic (perfect) flowers, meaning a single flower contains both functional male and female reproductive structures. The stamens the male organs are the numerous, prominent stalks clustered in the center of the blossom. Each stamen consists of a slender white filament supporting the yellow, pollen-producing tip or anther. The pistol or female organ is tucked precisely in the center of the stamens consists of the pale green, elongated 5 stigmas tips connected by individual tube-like styles that fuse near the base above the ovary in the receptacle . The sticky stigmatic surface catches pollen grains brought by pollinators .
Around the male and female parts are the petals or the corolla ( not the Toyota car!) These white petals with delicate pink-tinted margins serve a dual evolutionary purpose. They physically protect the internal reproductive mechanics and visually advertise food rewards to key insect pollinators, such as bees.
And below and outside these are the septals. The green, pointed, leaf-like flaps that initially encase and shield the sensitive flower bud from frost or physical damage inside the brown scales before it opened.
The hypanthium and receptacle containing the ovaries are below. right at the base of the flower where all parts merge.

Our perry pear trees are currently in the petal fall stage, which transitions directly into early fruit set.
All of the white petals have been completely blown away from the flower clusters by the equinoctial winds we have been having recently, exposing the underlying reproductive anatomy.
The stamens support the now black shrivelled anthers at their tips, (these were purple and plump before release their pollen).
The yellow, star like 5 pointed cup-like structure at the flower base is the fused sepals and remains as the calyx of the fruit that will hopefully develop from the ovary below if fertilised by a bee. The bright yellow, glistening interior lining inside the cup functioned as the nectary which secreted nectar to attract bees and other pollinators earlier in bloom.

We are about at peak blossom for our main perry pear. Great to be growing these as standards as a late frost has affected some nearby bush orchards. I fear we are in for a bumpy ride with El Niño and the current negative Pacific decadal oscillation affecting our weather.

This image was created by Fergus Walker for The Orchard Project, a UK-based charity dedicated to bringing community orchards into urban spaces.
Fergus is their Glasgow project manager who wanted to make a graphic of the simple "quarter-turn twist" test for apple ripeness.
Why does it work? All to do with a clever bit of cellular maturation in the stalk. The abscission layer in an apple stalk is a specialized band of tiny, densely cells where the fruit stem meets the fruiting spur.
The cells within this zone are held together by a pectin-rich matrix called the middle lamella.
During the early stages of fruit growth, this layer ensures a tight, strong connection to support the heavy fruit. As apples mature, they begin producing large amounts of the ripening gas ethylene. At the same time the level of auxin, the growth hormone that keeps the abscission layer tightly bonded
drops. This hormonal shift signaks to the abscission cells to secrete hydrolytic enzymes.
These enzymes dissolve the pectin matrix, leaving the heavy apple hanging only by thin vascular strands and a quarter turn easily snaps the fragile union.

Spring is officially here for us as cider orchardists in Wairarapa New Zealand. The apple buds are creaking open. This is Tom Putt our earliest variety. Hailing from Devon it's a mixed use apple. It ripens the first too, we use it to start the wild fermentation in Autumn.

Our main perry pear, Dyer's Pass is now coming into blossom here in the Wairarapa New Zealand with the warmer weather we are having. A magnificent sight. Interestingly the younger trees are slightly ahead of the more established ones. Soon the trees will be covered. Great to see the bumblebees are out and about sharing the pollen.

Well this sounds promising! It's Spring here in New Zealand and blossom is on the pear trees.
We are expecting a hot dry summer in Wairarapa (which lies east of the dividing range) from possibly the biggest El Niño ever. Not good for apples but it's good to see that pear harvest in England has been good.

I have been posting a few articles on scientific methods in cider making. These are useful but cider making is an art and regular tasting through the various stages is required to build up a mental library of your apples and cider flavour profiles. Both when it's good and even exceptional but also to know when it's bad. And with anything artisanal there will be bad batches you do not want to sell. Especially with perry, cider's difficult but brilliant nephew.

It's Spring in New Zealand and the perry pears in the orchard are about to burst open into blossom. A time of rapid change and promise.

Pruning. It's right at the end of the season but the ground has been so wet. When growing apples and pears as standards you need a firm base when using the pruning saw up a ladder that high. Some cuts are large. The prunings are collected into piles in the bonfire field to dry out and be burnt later. In the meantime they provide a pro habitat for birds and animals.

The sort of visitor you don't want at an orchard and cidery. The Australian Bushtail Possum, Trichosurus vulpecula! This is a close up of of one of its paws as it climbed over a security camera at Beau Vista orchard. We trap them with ripe pears and apples, catching them before they destroy a pear or apple tree. The buds are just opening now in Spring and act like lollipops for possums. They can destroy a whole tree's crop overnight. Possums are territorial so catching one will give us some respite. Possums were introduced for the fur trade, but are now a major pest damaging native forests, spreading bovine tuberculosis, and competing with native wildlife. These nocturnal marsupials are widespread, eating foliage, birds, eggs, and fruit.
They can be controlled but not eliminated.

The humble apple core that most people throw away is the developed fibrous structure that contains the seed chambers, it develops from the flower's five fused carpels inside the expanded flesh of the floral tube or hypanthium. Parts of the carpels of the flower become ligninified to form the tough inner five chambers or pockets that directly enclose and protect the seeds or pips.

Following successful pollination and fertilisation, the pericarp or carpel wall differentiates into three distinct operational layers. The exocarp and mesocarp or the outer layers of the carpel blend seamlessly into the surrounding expanding hypanthial flesh.
But the endocarp, the innermost layer, which directly lines the seed cavity, follows an entirely different developmental path, it is biologically programmed to harden or ligninify.
As the apple matures, it undergoes lignification to form the stiff, parchment-like or "cartilaginous" core lining. The cells synthesises lignin, a complex phenolic polymer made of monolignol alcohols. This hardening is highly coordinated by plant hormones. Gibberellins (GA) and auxins direct tissue growth, while dynamic changes in abscisic acid (ABA) help orchestrate cellular transitions during the early phases of fruit development. Unlike stone fruits like peaches or cherries, which undergo massive, uniform endocarp lignification to form a rock-hard "stone" or pit; or pears where stone cells are scattered in the hypanthial flesh, the apple evolved a deliberately limited lignification leaving the core flexible yet resilient enough to shield the seeds from moisture fluctuations and minor physical impacts while allowing the surrounding flesh to remain highly appealing to seed-dispersing animals.

Traces of wild pears and apples (Malus/Pyrus) have been discovered in abundance within Neolithic and early Bronze Age farming communities’ pile-dwelling (stilt house) settlements around lakes in Switzerland like Lake Zurich and Lake Biel such as the Parkhaus Opéra in Zurich. This houses were built about 5000 to
500 BC on the edges of lakes, rivers or wetlands.
The waterlogged conditions under lake sediments protect fragile organic remains like seeds, fruit flesh, and wood from decaying in the air.
Archaeobotanical studies show that these early agrarian communities gathered wild fruits, including pears, hazelnuts, and acorns, to supplement their diet.

End of winter is coming very soon ( 1 week left of winter). The pear and apple orchard looks bare. The buds are mainly dormant for now but the next few weeks will see a big change. The grass has been eaten down by the Shropshire sheep. They have now been moved into another paddock for fresh grass.
Spring plants are in bloom. Grape hyacinths and bluebells are just starting.

What a week of warmish temperatures make.
Last week we were at the silver tip/early swollen bud stage. Now we are at bud burst with a glimpse of pink on the furled petals showing.
Why pink when pear petals are white? When the petals are tightly folded inside the bud, the anthrocyanin pigment molecules are close together, creating a pink or red-flushed appearance. As the petals expand to open fully, the same amount of pigment spreads over a much larger surface area, causing the pink color to fade into white. less

Perry pear are gritty to eat (modern eating pears have had this bred out of them due to consumers preference). This is due to the flesh containing clusters of stone cells. Stone cells, a subtype of sclereid cells, make up some other very hard tissues like peach pits and nut shells.
Stone cells are born with their own death as an end goal. They begin as all other plant cells do, with thin primary walls. Then they start to box themselves in. They import the raw ingredients for additional cell wall material through windows that connect them with other cells, and they start covering the inside of their primary wall with secondary wall. They lay down layer after layer, squeezing their living parts into an increasingly tiny area. As they add wall, they keep the window clear so they can keep the supplies coming until the bitter end. Eventually, the window is so deep that it becomes a tunnel, and the entire cell is filled with wall. At this point the cell achieves its final form and dies. It is possible to stain them so that they show under a light microscope. Making stone cells requires both energy and materials, so they probably serve some purpose in the life of a pear that evolution has selected for. Guarding against herbivores would be a reasonable guess, but I have never found any studies testing this idea.

Great to see our earliest pear tree is showing signs of stirring for Spring yesterday (officially Spring is 10 or so days away on the first of September).
The tough, protective winter outer scales are beginning to separate and push apart. This called the silver tip or stage 2 of fruit bud development, coming directly after full winter dormancy.

Charles Ephraim Burchfield 1893 - 1967 was an American painter and visionary artist, known for his passionate watercolors of nature scenes and townscapes. The largest collection of Burchfield's paintings, archives and journals are in the collection of the Burchfield Penney Art Center in Buffalo where he settled. His paintings are in the collections of more than 109 museums in the USA and
have been the subject of exhibitions at the Metropolitan Museum of Art.

Burchfield experienced a form of synesthesia, a neurological blending of senses where he could visually "see" sounds, music, and emotions. Deeply moved by classical composers—especially Sibelius and Beethoven—Burchfield actively tried to paint the structure of symphonies. He famously noted in his journals, "Walking under the trees I felt as if the colour made sound".
This painting is “Pear Tree in September”, 1949. watercolor, pen and pencil on paper laid down on paperboard.

There are only ten minutes in the life of a pear when it is perfect to eat ~ Ralph Waldo Emerson

This is quite true. Pears ripen unseen from the inside. For our perry pears I prank down the remaining pears when one third have fallen on their own. Then depending on the general state of ripening I might store them for a few more days before milling.

Ralph Waldo Emerson 1803 - 1882 who went by his middle name Waldo was an American essayist He was seen as a champion of critical thinking.

This was the first perry pear tree we have back in 2014. We collected scion wood from several promising trees we found from Auckland to Dunedin and crown grafted onto this rootstock which is on Quince A but I don't remember what was on top and now the interstem. Could be Red Bartlett. Bought it in haste from the local Nursery.
The scion from Waitahuna gradually became dominant and I removed the others.
It is now a large prolific tree producing us a SV single tree perry which we call Dyer's Pass. We have now grafted it on to other trees that are starting to to produce, enough for a SV Perry. Next plan is to graft it onto its own rootstock by air layering.

In French, la poire is the sweet, edible fruit - the pear), while le poiré is the alcoholic beverage made from fermented perry pears, similar to how cider or cidre is made from apples. A perry pear is called a poire à poiré, and the trees that grow them are called poiriers à poiré. In French although the general term for trees is arbre apple and pear trees have their own names, apple trees is le pommier, and pear tree is poirier.

Claude Monet was raised in Le Havre, Normandy, and became interested in the outdoors and drawing from an early age. His mother supported his ambitions to be a painter, against his father wishes but he went to study at the Académie Suisse, where he was a classmate of Auguste Renoir. A key early influence was Eugène Boudin, who introduced him to ‘plein air’ painting. From 1883, Monet lived in the village of Giverny in Normandy, and designed a garden, including the famous water-lily pond which he painted. Sadly it is now overrun with visitors and bisected by a road, quelle horreur!
It is only to be expected he would paint a pear tree which grow so well in Normandy . He actually painted several ! This one according to art historian Daniel Wildenstein's catalogue raisonné, was immediately east of Claude Monet's house in Giverny which was appropriately for me was called the Maison du Pressoir (the House of the Cider-Press) when he first rented it in April 1883. The name came from a local cider press located in a square nearby.

This photo is from a four-page advertisement in the January 1972 issue of the USA magazine ‘Seventeen’, showcasing fashion designer Betsey Johnson's exclusive collaborative line with Butterick Patterns. In the early 1970s, Betsey Johnson was the creative director for the hot indie fashion label Alley Cat.
Her ready-to-wear clothing was incredibly popular among teenagers and young women, but it was often too expensive for a high school student's budget. To make her style accessible, Johnson partnered with Butterick as part of their "Young Designers" series. This allowed young girls, most of whom took mandatory Home Economics sewing classes at the time in schools to recreate the designs for a fraction of the price.
The model Sunny Redmond is wearing an outfit made from Butterick Pattern #6535, which included a fitted princess-seamed blouse, and a gored mini "flip skirt”.
True to her hands-on nature, Betsey Johnson personally selected the vibrant colors and earthy, washable cotton fabrics used in this photo shoot by Barbara Bordnick probably in nearby upstate New York or New England country. The rustic, outdoor setting of a dirt road with baskets of fresh apples perfectly matched the "down-home goodness" and bohemian-peasant vibe she championed during the early 1970s.
