A Wild Artichoke
It will be seen that this wild artichoke, in full bloom, is hardly three inches across. The flowerhead as a whole is strikingly suggestive of that of the thistle. This specimen gives a very good idea of the manner of flower from which the modern improved artichoke has been developed. Contrast this little flower with the giant in the next picture.
