XVI. Some Observations on Celeriac, with Directions for its 

 Cultivation. Bij Joseph Sabine, Esq. F. R. S. #c.

1 he Celeriac, though noticed in most of our Gardening 

 Books, is very seldom to be found in cultivation ; and even 

 where attempts have been made to grow it, they have gene- 

 rally failed. The French, who describe it under the name 

 of Celeri-Rave, seem to be also without a proper knowledge 

 of its management : for their accounts of it, as a vegetable, 

 are equally defective with our own. It is amongst the 

 German gardeners, who call it Knoll- Seller ie, that this plant 

 is brought to a great size. By means of an importation 

 from Hamburg into our market, we have, this winter, had 

 an opportunity of seeing how different it is, when properly 

 treated. Some of the roots, which were lately exhibited to 

 the Society, and which were a part of those imported, weighed 

 two pounds each, and were, on an average, fifteen inches in 

 circumference ; but I have reason to believe, that this was 

 the effect of extraordinary rich soil, and that the usual size 

 is about half of what is above stated, and then the roots are 

 always quite solid, not hollow as some of these large ones 

 proved. 



The Celeriac, like the common white and red Celery, is 

 derived, by cultivation, from the Apium graveolens, which 

 grows in different parts of Europe, and in England also, in
