80 ON THE TREATMENT OF TROPjEOI.UM TRICOLORUM. 



treme sweetness of its flowers. Like the Hyacinth, it will bloom in 

 glasses within doors, but much stronger in a small pot of sandy loam. 

 A few of its flowers will scent a whole apartment. 



The Chalcedonian Iris (Iris Susiana) was brought from Constanti- 

 nople to Vienna and Holland in 1573. It takes its name from Susa, 

 in Persia. This species thrives under the same treatment as the 

 others; but moisture, which favours the growth of them, is injurious, 

 and sometimes fatal to this. It is the largest and most showy of the 

 three.

ON THE TREATMENT OF TROP^OLUM TRICOLORUM. 



BY W. M. N., WORKSOP. 



Having long cultivated the Tropseolum tricolorum with great success, 

 as well as T. Jarratti, T. brachycerus, and T. pentaphylla ; and as 

 I have never seen, even at the Chiswick exhibition, better plants than 

 my own, the following remarks on my mode of treatment may be 

 serviceable to a young gardener, who asks for information in the 

 Cabinet, in No. 108. 



By Seed. — In February, steep the seeds twelve hours in tepid 

 water, then carefully denude them of the outer coat or skin, plant 

 them separately in thumb-pots, in a light sandy soil, and plunge in a 

 box of sand in bottom heat. In a month or six weeks the plants will 

 be up ; then remove them to the greenhouse, plunging each pot nearly 

 to the rim in a number 30-sized one, filled with good rich loam 

 and sand, well drained. When the foliage exhibits symptoms of 

 decay, withhold water. 



Treatment of full-grown Bulbs. — In the beginning of Fe- 

 bruary shake the bulbs out of the old soil, and plant in 36-sized pots, 

 in which small pieces of sandy turf are first placed for a free drain- 

 age, and then filled up with light sandy soil ; after which, place them 

 in a light and airy part of a greenhouse, giving a little water occa- 

 sionally. Prepare some good rich loam, mixing a little sand with it 

 to make it open, so that water may pass quickly away. Fill some 

 number 8-sized pots with this soil, having previously placed a good
