4 10 GARDEN PLANTS. PART II. 



TKOPCEOLACE.E. 



Tropceolum. 



None of the perennial species of this genus of beautifully 

 flowering plants will endure the heat of the plains. 



MALVACEAE. 



Althaea. 



A. rosea HOLLYHOCK Gool-Jchaira. It is questionable 

 whether this familiar biennial, except for old association, is 

 worthy of cultivation in this country, as it produces here 

 generally only single flowers, and those mostly of one colour 

 pink and not the splendid double ones which render it so fine 

 an ornament to gardens in England. Dr. Bonavia of Lucknow 

 has, however, lately brought to notice, that by sowing the seed 

 of some semi-double pink ones, in two years he has obtained all 

 the varieties one could desire, from white to prune-colour, and 

 many of them as double as they are in Europe.* The seed 

 should be sown in October, and, as the seedlings suffer severely 

 from being transplanted, in the bed where the plants are 

 intended to remain. The plants will sometimes blossom the 

 same season, or continue on till the following one, and blossom 

 then. In the latter case, however, many will most probably 

 perish in the Eains. 



Urena. 



U. lobata. A small shrub, with roundish leaves, of so harsh 

 and coarse a character, as all but to outweigh the beauty of the 

 little rose-coloured flowers it bears. 



Hibiscus. 



The gardens of India are very rich in the number of hand- 

 some species of this genus that they contain. But although 

 nearly all are very beautiful, there is not sufficient diversity of 

 character in many to make it worth while to cultivate more 

 than a select few. Most of them are very easily propagated by 

 cuttings or by seed.
