ON THE CULTIVATION OF THE TROP^OLUM TRICOLORUM.

( Translated from the Garten Zeitung for November \6th, 1839 .) 
Although the propagation of this very delicate twining plant is pretty 
generally known, I do not remember ever having read anything on raising 
it from seed. Allow me, therefore, to give you some account of my ex¬ 
periments on the subject. 
In the month of May, this year, I was fortunate enough to ripen a 
great quantity of the seed of this Tropseolum on very fine flowering spe¬ 
cimens in the garden of Mr. Decker, of this place. I immediately freed 
them from their outward covering, and sowed them in very sandy heath- 
mould. I first set the pot containing the seed in a pine-stove close under 
the window, but as I found they did not germinate there, I plunged the 
pot in a very warm hotbed, and here again I was unsuccessful, and not¬ 
withstanding the most attentive care for six months, I could not succeed 
in getting the seeds to germinate. As, however, I found them all in a 
good state, I tried the following experiment:— 
I took them all out of the pot, and put them in one filled with pure 
white sand; I set it on the warm flue of the pine stove, and kept the 
sand continually moist. In the course of two or three days I was greatly 
delighted to see that several seeds had germinated. As the plants began 
to develop themselves, I planted them singly in small pots, containing a 
mixture of heath-mould, with a great proportion of sand, and then set 
them to continue growing in a stove. It appears to me probable that 
plants of this Tropmolum raised from seed will produce larger tubers the 
first year than those usually do which are raised from cuttings.

Having already given an account of my experiments with the Tropceo- 
lum tricolorum raised from seed, I cannot refrain from communicating to 
the friends of gardening further observations on these beautiful twining 
plants. 
Those I raised from seed were very strong, and flowered abundantly 
last June. The stalk soon withered off after flowering, and on examination
