The 3Growbags Great Christmas Quiz 2025

Christmas is coming and it’s more than just the geese getting fat unfortunately. Too many mince pies and not enough gardening going on in The3Growbags lives, but we can still try to keep our brains in trim.

Get your glasses and the kettle on in that order and settle down to this year’s The3Growbags Great Christmas Quiz.

SECTION 1 🎄

Laura

Luckily you’ve got the most sensible sister first with the properly educational activity of Plant Identification. Can you give the common and scientific names of the following 10 plants? One mark for each part. And you get an extra pat on the back (and an extra mark) if you can also add a cultivar name for plants 1, 4, 5, 6, and 10. . I’ve had to throw in a couple of easy ones first to give Caroline a chance …

1.

I told you some of them would be easy, but can you give the scientific name and cultivar name of this very common annual?

2.

Another very recognisable character, but do you know which one it is?

3.

An impressive annual, but one that comes with a bit of a health warning as its seeds can be processed to make a deadly poison.

4.

A statuesque prairie plant and an absolute magnet for bees.

5.

Elaine and Caroline refuse to grow this tall beauty because of its wandering rootstock, but I forgive everything just to see its beautiful palmate leaves and soft apricot flower plumes.

6.

A glorious scent is the clue to this evergreen climber. Usually with white flowers, this is a cream coloured cultivar, and there’s another clue!

7.

A herbaceous spring flowering relative from a genus better known for annual scented climbers.

8.

This robust herbaceous plant pops up all over my garden, and the spikes of black berries make a great architectural contribution to the late summer garden. As happy in shade as it is in sun.

9.

This South American shrub revelled in the heat of the past summer, and gave us a harvest of unusual sweet-tasting fruit in late autumn.

10.

My final plant is one which, rather infuriatingly, Caroline can grow better than either Elaine or I, but only because of her acid soil and damp climate in the Highlands.

SECTION 2 🎅🏼

Elaine

Me now, and I’m a bit of a glutton for word puzzles. So I’m going to inflict some on you!

Have you noticed how things keep moving around the garden without any intervention from you at all?! The bugs jumped into the pear-tree, the doves flew into the lime tree, the toad leapt into the pond, and the bears lumbered into the woods (and we all know what they are going to do there 🤣) …..I know what! Let’s turn it into a word-game.  You must ‘move’ the first word in each line forwards by changing one letter at a time, until it has changed into the last word in each line:

  1. BUGS, ——, ——, ——-, PEAR

2. DOVE, ——, ——-, LIME

3. TOAD, ——, ——–, ——, POND

4. BEAR, ——-, ——–, ——-, ——-, WOOD

(2 points each)

Pond
Even small ponds bring loads of water loving wildlife into your garden – but are there any toads in there?!

Oooh, I love a cottage garden, with its glorious jumble of colourful, fragrant old-fashioned plants! Did someone say ‘jumble’? No surprise to my sisters, my cottage garden favourites have got themselves in a right old tangle.  Can you unscramble them by using the capitalised words in each line (nice easy one to start with..) :

Cottage garden
Just love a jumbled- up cottage garden full of old-fashioned flowers!
  1.  no SHOCK that the HOLLY can’t disguise these tall beauties.
  2. have LOADS of these bright flowers and your garden won’t be GRIM.
  3.  The garden HAS LAID mulch on these Mexican lovelies to help them through the winter.
  4. MERE GUITARS are not enough to serenade the prettiness of these daisies.
  5.  Does that border need some AID? I’LL GO for these flowers with their sword-like leaves.
  6. SO BRUSHERS past these bushes may catch a waft of sweet perfume (this answer is two words) 
  7. lovers of this early summer flower usually have a RABID DESIRE for more of them (another answer which is two words)

(2 points each)

Could be the answer to one of the questions………..?

Got all those word puzzles done and dusted? Let’s finish off this section with some horticulture-related trivia.  Do you know the answers to these :

  1. What is the surname of the sophisticated gentleman thief created by Maurice Leblanc for a Netflix series (a werewolf professor in Harry Potter books has the same surname)?
  2.  R. ‘Alnwick’ is a lovely shrub rose, but in which county are the famous gardens that gave this rose its name?
  3. Who wrote “A Garden is a Lovesome Thing. God wot” in the 19th century?
  4.  In what book of the bible do the lines “Consider the lilies of the field” occur? 
  5.  What is the surname of the man who has scored the most Test runs for England?
  6. ‘Silas Marner’ is a glorious David Austin rose, but who wrote the book?
  7.  What is the common name of Urtica dioica?
Rosa “Alnwick’ is a beauty, but in what county are the Alnwick Gardens?

(2 marks each)

Total for Section 2 – 36 marks

This upright, compact shrub has huge appeal at this time of the year with gorgeous red/purple berries. Louise recommends planting it at the end of the bed – find out more about her Great Plant this Month…


The great Growbags’ amaryllis humiliation!

In October we challenged everyone to see if they could get their amaryllis bulbs to flower during Christmas week. At least ALL of us Growbags utterly failed at this – which is better than one of us succeeding and being smug . How about you? Please email us your images to thegirls@the3growbags.com
