Today’s Flowers #93 May in the garden

Suddenly the garden is full of flowers and bees and insects - and life! We saw our first damselfly yesterday hovering over the pond and a small newt today near the surface.
All photos should enlarge when clicked - but there again, they may not . . .

Exochorda x macrantha 'The bride'

Sometimes known as 'Pearl Bush'

Syringa -commonly known as Lilac

A lilac Lilac

Choisya ternata - Mexican Orange Blossom

Physocarpus opulifolius - Common Ninebark with visitor. The buds are tightly shut at present but will open to white flowers that are very popular with bees

Syringa, Lunaria and Rosmarinus officinalis - Lilac, Honesty and Rosemary

Lavandula stoechas 'Papillon' - usually simply called Lavender

Ilex Altaclerensis Golden King - variegated holly

Despite its name this is a female self-fertile shrub. I am delighted to see flowers this year - there were none last year. The white flowers attract flying pollinators though this cluster of flowers and buds has been visited by an ant. In case the picture cannot be enlarged, the cropped shot below shows it more clearly.

Spring 2010

Has Spring sprung or merely gently yawned and stretched?
Last night, for the first time this year, I heard a frog calling with that distinctive rolling chirp. In 2009 the frogs started singing a full month earlier than this. There are a few individuals in our pond and the fish are swimming about in the expectation of tasty frogs' eggs though I think they may be disappointed for a while yet (not French, our fish, nor gastronomes – no taste for grenouilles). I'll feed them anyway so that some spawn may survive – if eventually it is deposited.
Spring is certainly taking its time to wake up. The Spring flowers are late. Usually the tête-à-tête daffodils are in full bloom by St David's Day on 1^st March but they've only opened in the past week. Other daffodils in the garden and in pots are still in bud, their glories yet to be revealed. Tree buds are beginning to ripen but everything seems reluctant to show itself.

Common Ninebark  (Physocarpus Opulifolius) 'Dart's Gold'

I suppose Spring always enters shyly, disclosing her beauty gradually so that we may appreciate it the more. Our Common Ninebark (Physocarpus Opulifolius) is almost in leaf – I love the bright yellow-green of its foliage and of course the hazel catkins are shaking their tails in the breeze.

 Corkscrew hazel (Corylus avellana contorta)

I discovered some hellebores bravely blooming, their heads barely raised above the ground. The crocuses were late, too, and the lone snowdrop I've seen stands tall and proud – and late - in the shelter of the ninebark.

Perhaps Spring is performing the dance of the seven veils. Maybe she always does but as I look out on this dank March day I feel that this year she is being unnecessarily coy. If the sun shines later – or ever – I will definitely feel more hopeful but for now the wind is sharpening and the drizzle is determined to grow up into rain.

Flower Crampons for Busy Bees

Many plants rely on insects for pollination. The insect that probably comes to mind most readily as a pollinator is the bee.

Some flowers have petals covered in tiny cells like pyramids and scientists have discovered that the purpose of these conical structures is to help bees get a good foothold. In order to discover this the researchers created very convincing artificial flowers from epoxy resin, making some with cones and some without. A sugar solution was placed inside and bumble bees were set free in the laboratory to ascertain their preference.

When the flowers were horizontal the bees showed no particular inclination, treating coned and coneless flowers impartially. However, when the flowers were angled the bees preferred the rough surfaces to the smooth and more so as the angles grew steeper. High-speed film showed that on the smooth petals the bees’ feet were unable to gain a good purchase and they were having to beat their wings fast to maintain their position, using a great deal of energy in the process.

In a separate study the pyramidal cells were found to act like solar panels, warming the petals and the nectar which benefitted the bees, allowing them to use their energy for their prime purpose of collecting nectar and pollen.

In the following photographs there are different species of bees. Bee identification is not one of my skills so I am unsure of naming them correctly!
