Future invaders at RHS Chelsea

Posted on February 11, 2019 by Tomos Jones

I’m heading to RHS Chelsea 2019!

I’m delighted to announce that I’ll be at the RHS Chelsea Flower Show 2019, with an exhibit called Ornamental plants: our future invaders? in the Discovery Zone. This is part of my PhD project on identifying ornamental plants with invasive potential. This is an exciting (but equally daunting) opportunity; to be at what is arguably the most famous of flower shows. I remember watching TV coverage of the Show many years ago with my Taid (grandfather), who originally got me interested in gardening. I’ll be writing a few blogs as I prepare for the Show. Firstly, the inspiration for the concept.

The concept

The exhibit will explain the detrimental ecological impacts that invasive ornamental plants can have on the wider environment. The original idea came from wanting to explain the naturalisation-invasion process (Fig.1). That is, how ornamental plants are introduced intentionally for horticulture, and some of these then ‘escape beyond the garden fence’ and might become invasive (represented by the red arrows). The black arrows represent the factors that influence this process.

Fig.1: The naturalisation-invasion process. Adapted from Levine et al. (2004:976) and Milbau and Stout (2008: 309).

The plants for this exhibit have been selected to represent this process; including plants which might become invasive in the future due to climate change. The choice of plants is also a direct result of my current online survey, asking gardeners to help identify the invasive ornamental plants of the future. You can help by joining over 450 gardeners who have already completed the survey. I’ll be sharing more information about my choice of plants – and the challenge of having them looking beautiful for Chelsea – soon!

The role of gardeners

Gardeners have an important role in preventing and managing invasive plants. Not only can they be the first to observe plants showing signs of invasive characteristics, but it is also important that gardeners dispose of their garden waste responsibly. For example, not throwing unwanted plants over the garden fence because these can then flourish. Click here for the RHS advice on responsible disposal of ornamental plants. Not only will the exhibit have this educational purpose, visitors will also have the opportunity to report plants these they are finding to be invasive or problematic in their own gardens and give information on their management – contributing to this important field of research.

#AdventBotany 2018, Day 25: Naughty or Nice?

Posted on December 25, 2018 by Alastair Culham

By Claire Smith

This image is licensed from Wikimedia Commons under CC BY-SA 3.0.

Are you on Santa’s Naughty or Nice list this year? If all you’ve discovered in the toe of your stocking this morning is a lump of coal, it might not be as terrible a present as you think. Look closely, and you might find that Father Christmas has brought you a fossil plant or two!

Coal is formed from dead and only partially decayed plant material.  Essentially it is peat that has been subjected to heat and high pressure changing it from the soft brown material widely used in gardening into the hard black coal. Continue reading →

#AdventBotany 2018, Day 24: The hunt for Disa x brendae

Posted on December 24, 2018 by Alastair Culham

Disa caulescens

Neither my partner Ben nor I actively celebrate Christmas. We prefer to hide away from the crazy world that Christmas has become and endeavour to find ourselves as far away from humanity as we are able. Previous years Christmas avoidance techniques have seen us winter climbing on a mountain in Snowdonia, snowed in in a bothy on an off-grid peninsula in Scotland and searching for Narcissi in the driest parts of the highlands of the Negev desert. Last year we found ourselves, on Christmas day, in a little explored valley on a mountain in South Africa; an adventure that I will tell you about forthwith. Continue reading →

#AdventBotany 2018, Day 23: I met Tunnicliffe in a forest of Conifers

Posted on December 23, 2018 by Alastair Culham

by Claire Smith

As children I’m sure we’ve all sprinkled far too much glitter onto a pine cone and hung it from the Christmas tree… but have you ever wondered where your festive pine cones come from?

Well, you could have a look through this Forestry Commission 1966 “Know Your Conifers” booklet with cover art by Charles Tunnicliffe. If you’d prefer a paper version to the PDF, The MERL have both the 1966 and 1970 editions in their library. You can phone the The MERL on 0118 378 8660 if you’d like to make an appointment to have a look. Their collections also include further examples of Tunnicliffe’s artwork, including the seasonal “What to Look For…” Ladybird books.

#AdventBotany 2018, Day 22: Thyme for a good stuffing

Posted on December 22, 2018 by Alastair Culham

By Fi Young

Thymus in flower

Sage and onion stuffing seems to be the norm for stuffing a Christmas turkey, but what about using thyme?  A Google search produced 9 million results!  A quick look through the first five pages of the search shows that thyme can be mixed with a variety of plants.  The most common are : onions, parsley, apple, lemon, orange and chestnuts.

But what exactly is thyme?

Thyme or to provide its correct botanical Latin genus name: Thymus vulgaris L. [1] is a member of the Lamiaceae (mint family) and according to Mabberley [2] thyme is distributed from the West Mediterranean to South East Italy. Continue reading →

#AdventBotany 2018, Day 21: A botanical pick-me up for the bleak midwinter

Posted on December 21, 2018 by Alastair Culham

By Rachel Webster

Rachel’s Coffee

With four previous years of Advent Botany I was surprised that none of us have so far covered coffee. OK, it’s not a Christmassy spice, or a festive decoration, but by this time in the year I’m sure I’m not the only one feeling more than my usual need for this botanical pick-me-up. As we reach the shortest day of the year a good cup (or several) of coffee is pretty much all that’s keeping me from attempting to hibernate. Continue reading →

#AdventBotany 2018, Day 20: Once upon a time: A tale of fairies from the RHS herbarium

Posted on December 20, 2018 by Alastair Culham

By Yvette Harvey

I am still pondering why a pagan spirit of the dead, or, more recently a demoted angel, should play such a big part in Christmas – for Christmas certainly wouldn’t be the same without a fairy at the top of the tree or strings of fairy lights illuminating more than you thought humanly possible.

#AdventBotany 2018, Day 19: Sir Gawain and the Green Knight; a spot of medieval Advent Botany

Posted on December 19, 2018 by Alastair Culham

By Alex Mills

So, it’s Christmas time. You’re having a bit of food with your friends and family. Well, a lot of food. It’s Christmas, isn’t it? It’s all very convivial and jolly and all that.

Suddenly, there’s a commotion at the door. A big chap has come in. He’s on a horse. He’s a really big chap. He challenges the room for one to come forward for a game. A Christmas game. It seems to involve a big axe. A really big axe. What do you do? Do you accept the challenge? This guy looks like he can handle himself in a fight. This guy and his horse are, incidentally, both, completely, from top to toe (hair, mane, beard, tail, clothes, and skin), completely ‘enker grene.’[1] Yup: enker grene. Bright green.

#AdventBotany 2018, Day 18: Advent VLOG

Posted on December 18, 2018 by Alastair Culham

By Dawn Bazely

Dawn is one of our long-standing contributors and has contributed: poinsettias, cranberries, red-osier dogwood, amaryllis, white cedar, balsam fir, paperwhites, ivy, candy cane chrysanthemums, and less traditional plant species associated with the British festive season, such as arctic cotton grass and willow, and gourds.  This year, to celebrate the 5th Anniversary of #AdventBotany, she has branched out into the tecnology of the VLOG!  I’m impressed to see the qualtity of local produce she has access to in local stores.

Editor’s note

Dawn mentions Pine cones in her Vlog and we have an advent blog coming later that features the various types of pine cones.  For tree species used as Christmas trees see The Christmas Tree.

Here are some links to further information kindly provided by Dawn.

#AdventBotany 2018 Day 17: The Chestnut Song

Posted on December 17, 2018 by Alastair Culham

By Katherine Preston

Today’s blog is the second by a Botanist in the Kitchen, this time Katherine.  It is a revisit of the sweet chestnut, last featured in 2015 when we heard about the devastating chestnut blight.  In today’s blog we hear tell of the rather grown up flavour of the chestnut and a need for lowered expectations.

The sweet chestnut of Europe is a true chestnut (Castanea sativa), not the beautiful but toxic horse chestnut (Aesculus hippocastanum), which so famously covers Paris with its pink-eyed blossoms in April. They are not very close relatives, as the last common ancestor of sweet Castanea (Fagaceae) and showy Aesculus (Sapindaceae) is estimated to have lived about 100 million years ago. I have happily returned to Paris many times in the summer and fallen in love with its horse chestnut trees. In that frozen moment in December, however, the spell of Christmastime in the City of Lights was broken for me when I realized that I could live happily without any more true Castanea chestnuts.
