A rose that's been colored green! I believe there are a few bushes that can grow greenish roses, but I definitely know you can get a white rose, stick it in a jar of water with food coloring, and in a while it'll be green!
Green is the colour of esperanto, so it's probably a significant choice of colour rather than a weird choice of flower.
The green rose is exactly that -- a rose varietal that is green in color. There are two kinds: the original without petals, and the more modern mutated forms that have actual flower petals in varying shades of green. Beware of those who offer seeds: the original green rose does not produce pollen and cannot produce "seeds". It can only be reproduced by cloning (cuttings).
I first saw these in a comprehensive rose handbook back when I was researching old roses (ie, non-hybrid types).
Is there a difference in saying 'The beginner has a green rose' and ' The beginner has green roses'?
Yes, 'The beginner has green roses' would be 'La komencanto havas verdajn rozojn'. The 'j' before the accusative 'n' indicates plural - note that the adjectives for the plural word also get a 'j'
There's a problem here... when I do the listening exercise, it only accepts it with a period at the end - I quintuple-checked my spelling. I feel that's a little pedantic, but don't know how to go about reporting it.
