After a short-notice teaching cancellation and sight of the forecast for glorious sunny weather, we marked the spring equinox with a leisurely train ride to Cambridge, a day in the Botanic Garden, topped off with a lovely meal in the Station Tavern. What a great way to celebrate the season!

As always we were on the look out for wildlife other than the plants, and as the warmest day of spring so far, it was not surprising there were quite a few sparkling Brimstones in action, along with singing Goldcrests in several places. A few things stood still long enough for photos including the planthopper Eupteryx decemnotata, a species first recorded in this country as recently as 2002 and the rarer of two similar bugs found on sages and their relatives, and an early-season, free-range micromoth Diurnea fagella.

Other good finds included a Tree Bumblebee seeking a nest hole; indeed queen bumbles, primarily Buff-tailed, were everywhere, albeit concentrated on certain forage plants, most notably Nonea lutea and the winter-flowering heathers. Honeybees too were widespread and active, on heathers and Scilla especially, and drinking water from the ponds.

Otherwise, there were ladybirds making more ladybirds, Moorhens stalking the reedy patches, and the obvious galls of the fly Taxomyia taxi on Yew.

Being so early in the year, many of the wonderful array of trees in the garden were devoid of leaf, but all the better to show off their often distinctive shapes and bark. This was apparent even at our traditional first stop, outside the tea room, where the sunlit awning projected the tracery of branches, not fully formed leaves.

And then the other natural art in the garden: the lichens on the branches, the sun splashing everything with rich colours. Who needs flowers?

But of course there were signs of many of the trees and shrubs springing into life, producing flowers (some even in fruit), whether wind-pollinated danglers …

… or more showy insect-pollinated blooms.

Mistletoe was also really obvious on the bare trees and shrubs, very golden-green in colour, especially male plants. The two sexes have rather different flowers, the females small with a rounded ovary, males larger with more splayed, fleshy petals on which the pollen is borne directly.

And although many of the beds were still quite bare, having had their spring-clean, there were still plenty of exciting perennials in flower….

… but particularly interesting to me were the flowering Mandrake (an old friend, and a plant rich in folklore that I used to know from my spring trips to parts of the Mediterranean), Yellow Star-of Bethlehem (a scarce native that I have never yet tracked down in the wild) and the beautiful wild form of Wild Daffodil, lemony tepals contrasting with the deeper yellow trumpets.

And all that was left were the glorious glasshouses, where an even more diverse array of flowers, fruits, foliage and forms can be found, where you can visit almost every continent without burning up carbon, and immerse oneself in the fragile beauty of the botanical world around us.
