DICTA MNUS. Fraxinella, or Dittany. (Dictamnus, 

 a name adopted from Virgil ; Fraxinella, a diminutive of 

 fraxinus, the ash, from the similarity of their leaves. 

 Nat. ord. Rueworts [Rutaceae]. Linn. lo-Decandria, i- 

 Monogynia.) 



This is one of the oldest and best border-plants of our 

 cottage-gardens. Instances are known where the Fraxi- 

 nella has outlived father, son, and grandson in the same 

 spot, without increase, all attempts at multiplying it, to 

 give away a rooted slip to a newly-married member of 

 the family, having failed ; yet the Fraxinella is easily 

 increased from seeds. Sow, as soon as they are ripe, 

 in the common soil of the border, and cover one inch 

 deep ; they will not sprout till the following April. If 

 they are kept over the winter, and sown in the following 

 spring, they will remain twelve months before they 

 sprout ; and not one seed out of a hundred sprouts at 

 all. When the seedlings are two years old, transplant 

 them where they are to remain, and they will flower the 

 third season. They prefer a deep, rich border, on a 

 dry bottom, and all flower in June.
