It is considered a "remarkable plant," and a very valua- 

 ble acquisition for gardens. 



" A few years ago," says Dr. Lindley, " a blue nastur- 

 tium was classed in the same class of impossibilities as a 

 Hippogriff or a Unicorn, for men's minds were warped, and 

 their vision distorted by the theory of cyanic and zanthic 

 series in flowers, which could not, as it was said, interfere 

 with each other. It was asserted that, in those cases where 

 a pure yellow is observable in a particular genus, no blue 

 could possibly be produced, and that, on the contrary, Avhere 

 a blue color exists in a genus, yellow was expelled. Here, 

 however, is a genus, in which all the species previously dis- 

 covered were either yellow, or some color in which yellow 

 occurs in manifest combination : but the T. azdreum has 

 no yellow at all, the blue being as perfect as that of the 

 Siberian larkspur. 



" It is then no longer safe to assert that a blue dahlia, or a 

 yellow pelargonium, or a yellow pgeony are impossibilities. 

 There is no telling how soon art or accident may produce 

 every one of them." 



The roots should be potted in August or September, in 

 rich sandy loam and leaf mould, with a good portion of 

 sand : place the pots in a sheltered situation in the open 

 air, where they may remain till taken into the green-house 

 with the other plants. Place them in an airy situation, 

 where there is plenty of light, and they will tlower freely 

 from April to June. Gradually withhold water from the 

 roots when done flowering, and allow the bulbs to remain 

 in the pots till the season arrives for potting again. The 

 cuttings root readily. The plants are splendid objects 

 when trained to a fancy trellis of wire- work. We hope to 

 see it speedily introduced. {Bot. Reg., Dec.)
