They thrive in the worst soil and survive our winters. Virgil [Translator's note: Eclogues, 

 5a 39] mentioned this tree: 



In place of gentle violet, and narcissus now forlorn, 

 The thistle grows, and the sharp Jerusalem thorn, etc. 



CULTIVATION. This shrub is propagated from suckers and from seeds that sprout 

 promptly, provided that their envelopes are stripped off before they're planted. 



KEY TO PLATE. 



54. Jerusalem thorn. 1. Complete flower, enlarged. 2. Fruit.
