Christmas and the Botanic Garden

By

Being out and about in the Garden gives a sense of the changing of the seasons, a sense brought about by the combination of light, temperature, wildlife and, of course, plants. This is felt most keenly at this time when we are the furthest from the sun that we will be, until next year. I find mid-winter an uplifting time; leafless trees show their bones and wildlife is easier to spot. It’s amazing how much life is flitting around in an old oak tree when you take the time to look into its branches. The sky seems bigger in winter and the sunsets more vivid. This might just be that we don’t get to see them so much in midsummer, but at this time of year we see the sun rise in the Garden and set in the Garden.

From this moment the days get a little longer and we begin to see

movement in the soil, small signposts to spring that don’t occur before midwinter. Snowdrops and winter aconite emerge in January; tiny and fragrant flowers emerge on shrubs such as witch-hazel, Daphne, winter flowering honey suckle and Christmas box. These plants need to attract the few pollinators that may be around from long distances, hence using strong scent rather that the colourful showy flowers we see through summer.


In the low sun and with the soundtrack of robins, crows and the odd fidgety group of goldfinches, we spend the winter tidying and weeding the borders knowing that they’ll stay tidy and weed free until spring. Structural work takes place on trees, landscaping of areas that need developing and of course repotting of collections inside. Winter can be hard work, but it keeps us warm and is always good to keep projects moving while we can.

Throughout the Christmas period someone must come into the Garden to water the glasshouses, check the boiler is working and eat the chocolates. So even on Christmas Day there is a member of staff working in the Garden for a few hours. In some ways it’s a nice to escape the Christmas mayhem for a while in the tranquillity of a warm glasshouse, unless of course there’s a small flood, snow or an electrical trip to deal with. Whatever happens on our Christmas duty there are many gifts brought in by our volunteers in the form of chocolate, cake, biscuits and pies, it is difficult not to pop a chocolate in our mouths when passing; sometimes the work means we pass quite a lot…

There is one Christmas tradition that we’ve been interested in for the last few years. Did you know that in the Mexican city of Oaxaca the 23rdDecember is the Noche de Los Rábanos, the Night of the Radishes. Since 1897 displays of ornately carved radishes have been a prominent part of the Oaxaca Christmas market; and here, many miles away, we’ve had a go on the 23rdfor the last four years. Maybe not as extravagant as the Mexican markets, but a good try.

Enjoy this midwinter break whatever you’re doing, and from the Botanic Garden we wish you all much laughter and warmth to take you into 2018.

Winter and the sacred lotus

By Matt Philpott, Botanic Garden

Late summer seems like a lifetime ago now the days are short and we’ve seen the first frosts of the season. But, if I cast my mind back to the first time I stepped into our tropical glasshouse this summer, as a shiny new trainee….I wiped clean my foggy glasses and was immediately blown away by the stunning Sacred Lotus (Nelumbo nucifera), in full flower in the pool. The vibrant colours and sheer height of the flowers looked stunning against the backdrop of green foliage in the glasshouse.


The Sacred Lotus is a fascinating plant that’s been cultivated in China for over 3,000 years. It’s now grown around the world, not just for the gorgeous flowers, but for deep cultural and religious significance to Hindus and Buddhists, as well as a source of medicine and food.

It didn’t occur to me on that first day quite how much work goes on behind the scenes to keep this beautiful plant at its best every year. Over the last few months I’m very privileged to have found out how to grow the lotus first hand.


The Sacred Lotus is an aquatic perennial, which due to the short and cold UK winter days, slows down and enters a dormant period here in Bristol. While our tropical glasshouse is still pretty toasty in the winter, the pool isn’t heated. (A cold pool in a plus 20 degree room never fails to surprise me when I hop in!) During the winter, to ensure the best possible display when the lotus returns to growth in the next spring, we take the plants out of the pool to rest in cooler and drier conditions.


The lotus started to slow down and stopped flowering in our glasshouse in October and over a couple of weeks we gradually pruned back all of the remaining leaves. The lotus are potted up in containers to prevent them from completely taking over the tropical pool. Which means it’s possible to dig about in their muddy home and lift the pots out of the water. Having said that, it was still a three man job to lift the water logged lotus out of the water! They sat on the sides of the pool (releasing a pungent smell of decomposition) before we tidied them up and moved them to a cooler glasshouse where they’ll recuperate over winter, ready for a burst of growth in spring.


Having spent a day pulling the plants out of a muddy pool I can certainly understand why Buddhists see the lotus as a symbol of beauty and purity – when contrasted with the dark mud they grow out of.

The loss of the lotus has left the pool looking just a little bit bare at this time of year. That is apart from the ever-present Duckweed, which never fails to impress me with how quickly it jumps back after a day of netting! The pool might be sparse right now, but it will all be worth it when our visitors enjoy the majesty of the complex and beautiful flowers of the Sacred Lotus next year.


So, here’s looking forward to longer days. I now know what it takes to put on that amazing summer lotus show and feel I’ve earnt the joy of looking at them next year just that little bit more.
