Omphalodes. [Boraginaceae.] A germs containing two 

 favorite plants, — the annual Venus's Navel-wort, and the 

 early blooming dwarf O. verna, whose pretty little bright 

 blue flowers are mistaken by persons not skilled in plants 

 for the Forget-me-not, a very different thing. Both are of 

 the easiest culture. The perennial will increase to any ex- 

 tent by division, and, when once planted, need not be dis- 

 turbed for years ; for, within moderate limits, the larger the 

 patch of such diminutive subjects, the better. It is very 

 suitable for rock-work which is not too dry and exposed. The 

 annual may be sown in the borders, towards the end of 

 March, and again in May for a succession, and requires only 

 good garden soil.
