Gree.nhouse and Stnvp Plants. 



ami interfere with the next season's growth. 

 They must be wintei-ed at the warmest end 

 of the hardwooded house, if there is not 

 other accommodation for them ; but they 

 will do much better if they can be placed 

 where they can receive from 40° to 45° in 

 the night, until the temperature is brought 

 up to that by solar heat, as this Roella 

 cannot bear without injury so low a tem- 

 perature as many plants indigenous to the 

 same country. Tie out nicely, so as to 

 keep their branches in the required posi- 

 tion, for it is naturally procumbent in 

 growth, and if not tied up it will lie over 

 the pot so as to receive injury and have an 

 unsightly appearance. Again, about the 

 beginning of March, repot ; the strongest 

 will bear moving into pots 3 inches larger ; 

 to such as ai'e weaker do not give more 

 than a couple of inches more room. Now, 

 as the plants get stronger, use the soil a 

 little more lumpy — it will do broken about 

 the size of walnuts. As before, tie the 

 branches out to the rim of the pot ; after 

 potting treat as in the preceding season as 

 to water, keeping the house for a few weeks 

 ,a little closer, until the roots have begun 

 to take to the soil, and closing with sun- 

 heat and moisture. 



It is now time to decide what is to be 

 ■done with the plants in regard to allowing 

 all or a portion to flower. If the whole are 

 grown simply for decorative purposes, then 

 it is best to allow them to bloom, which 

 they will do freely from the points of 

 •every shoot. If some are required to be 

 grown on larger, these should again have 

 their flowers removed as soon as they are 

 formed. Those that are allowed to flower 

 may, when in bloom, be removed to tlie 

 conservatory, and placeil where they will 

 receive plenty of light and not be over- 

 crowded ; as soon as they have done flower- 

 ing move them back to the hardwooded 

 house, and pick all the old flowers off. 

 This is a matter of the greatest importance 

 with this plant at all times, but more es- 

 pecially if they are allowed to open any 

 during the autumn or winter ; for if no^t 

 ■immediately removed after they have de- 

 cayed, they begin to mould, and will kill 

 almost every shoot right back as far as the 

 season's growth, and very often destroy the 

 plant. This is a singular peculiarity to 

 which this Roella is subject under cultiva- 

 tion ; no doubt owing to the natural con- 

 dition of the wood not being calculated to 

 resist the effects produced by the confined 

 atmosphere of a plant-house, which causes 

 the flowers after they have closed to be- 

 come mouldy. 



After blooming, grow them on with the 

 .others that have not been allowed to 



flower, treating them as in the preceding 

 season in every way, except that none will 

 this season require another pot. As 

 autumn approaches, again give more air, 

 day and night, so as to mature the wood ; 

 but not even when they get large must 

 they be fully exposed to the open air, as 

 the plant does not well bear such treat- 

 ment, exposure only aggravating the rusty 

 appearance of the leaves, without being of 

 any benefit. 



A full crop of flowers will no doubt be 

 again formed this autumn, and should be 

 removed ; winter the plants in a tempera- 

 ture similar to such as recommended the 

 previous season, near the glass in a light 

 house. In the spring, about the same time 

 as heretofore, move again, giving them 

 pots, as before, 3 inches larger, which is as 

 large a shift as this plant ever requires. 

 After they are potted, give the same treat- 

 ment as advised for the preceding seasons ; 

 they will this year make nice young 

 flowering specimens, and may be allowed 

 to bloom either for conservatory decoration 

 or for exhibition if required, where the 

 plants, from their uncommon colour, are 

 always eftective. If wanted for showing 

 later in the season, say about August, they 

 will, if all the flowers are taken off in the 

 spring, set a second crop later on, which 

 will come in about the time indicated. 

 Through the autumn and winter keep as 

 in the past years, tying them nicely into 

 shape ; pot as before, and at a similar time 

 in the spring. This season, if all has gone 

 well with them, they will be large enough 

 to exhibit in any collection of plants, if 

 they are required for such purpose ; and 

 for the time to come let the general routine 

 of their culture be similar to that which 

 has been advised through the early stages 

 of their existence. 



Insects. — In the cultivation of this 

 plant one of the principal things to be 

 guarded again.st is mildew. Whenever 

 this makes its appearance sulphur should 

 at once be applied. The plant is little 

 subject to the attacks of insects. If it 

 stands so as to touch others that are 

 affected with brown scale, or under a plant 

 upon which this insect exists, it will get 

 upon it, but does not increase fast, ancl it 

 can be easily kept down by going over the 

 plant with a small brush at times. This is 

 the only insect we have ever seen it troubled 

 with.

These handsome cool stove plants have 

 never been so much grown as the beauty 

 of their flowers warrants, and where their
