The name, Mathiola, was adopted after that of 
Peter Mathiola, an Italian physician. Annua, from 
the Latin, denoting its duration as annual only. 
Very few plants have been so diversified in their 
varieties, as the Ten-week Stock. Every gradation 
of colour, through all the shades of pink and purple, 
to a white, have been produced ; and even imper- 
fect tints of brown have appeared, mingled with 
its more legitimate hues. 
Seeds of the most beautiful varieties of Stocks are 
imported from Germany ; where, it is said, by con- 
sent, or some municipal regulation, only one variety 
or colour is allowed to be grown in each village, 
and thus their shades are kept distinct. They are 
mostly packed in sets or collections, each consisting 
of about forty sorts, labelled according to colour. 
In raising Ten- week Stocks, more care is required 
than is always practised ; and there are but few per- 
sons who have regularly cultivated this flower, par- 
ticularly by the aid of artificial heat, but have expe- 
rienced disappointment, by seeing their young seed- 
lings, when two or three weeks old, die away, plant 
by plant, till a very slender crop has remained.
