 a magnificent inflorescence at the Royal Horti- 

 cultural Society's meeting on February 6 last. 

 As to the derivation of the hybrid there is some 

 doubt. The record on one side is said to be 0. 

 amabile, and on the other a fine hybrid raised 

 by Messrs. Sander & Sons and named 0. Royal 

 Sovereign, but the record was somewhat in

 Good mulchings on the border, kept in place by 

 a few boards, so pitched as to throw off super- 

 fluous moisture, are a great htlp. as are 

 also mats, or straw hurdles placed against the 

 wall. The young growths are often close to the 

 roof-glass, and a mat placed over the glass in 

 severe weather is very beneficial. There should 

 not be much humidity in the atmosphere of the 



doubt and therefore perhaps it is better to con- house for the prpsentj and any drips from con . 



elude that the parentage is unknown. As will 

 be seen, it is a very good hybrid, with the 

 flowers of fine shape and segments w T ell dis- 

 played. The colour is deep claret-purple with 

 a few lines of the -jvhite ground showing through, 

 the tips being white tinged with rose. The lip 

 has a yellow crest and white front lobe with 

 rich claret-coloured markings.

THE ROSARY.

CULTURAL HINTS FOR FEBRUARY. 



It is the practice of many to apply heavy 

 mulchings of manure to Roses in winter, but I do 

 not recommend it. In such a wet season as this 

 the manure becomes a wet mass around the base 

 of the plant, which is the most vital part. It is 

 my experience that the plants are much safer 

 when kept dry. The fertilising properties of the 

 mulch are of little, if any, value to the plants in 

 winter, seeing that the roots are not active. 



Instead of these moisture-conserving mulches, 

 I recommend drawing up some of the soil to- 

 wards the stems to throw off the rains. This is a 

 certain protection against injury by frost to the 

 base of the stems of dwarf Roses, and it is 

 useless to protect the upper wood and leave the 

 base exposed to both frost and wet; for this is 

 the part that is soonest injured. 



If, instead of manures, strawy litter is applied, 

 the latter is either blown to some corner, where 

 it is not wanted, or else battered down by snow 

 or rain. Nurserymen, with their many thou- 

 sands of plants, seldom protect Roses, but they 

 endeavour to keep the plants as dry at the bot- 

 tom as possible. This season being so wet, we 

 have drained the rows on Rose quarters by 

 making small gullies with a spade or hoe. 



Perhaps the best protective materials for 

 Roses are branches of Fir, Beech or Laurel. 

 These can be applied quickly and they posses 

 the great advantage of staying where they are 

 placed. They do not harbour wet, but form a 

 protection from cold winds and frosts. Tender 

 varieties should not be grown as standards, for 

 in this type of plant the most vital part is where 

 scion and stock unite. This part of the plant 

 will naturally be dry, and it may be protected 

 from frost by tying a small tuft of hay, straw 

 or bracken about it. I have seen cases where the 

 tops of the plants were trussed up with straw 

 much after the manner of bottle protectors. Al- 

 though this undoubtedly protects them, it also 

 has the effect of making the plants tender and it 

 induces a premature growth. Very tender varie- 

 ties I would protect, but these should not be 

 planted, except in warm, sheltered positions. 

 1 would warn cultivators against early pruning, 

 formerly some of the hardy Damask and Gallica 

 Roses, also a few of the Hybrid Perpetuals, were 

 pruned in the last week of February. I do not 

 agree with this early pruning, especially now 

 that we have a large number of varieties half- 

 way between the old ones and those that are 

 sometimes stvled twirW

densed moisture should be prevented, as these 

 are frequently the cause of the leaves and young 

 flower-buds dropping. As growth progresses 

 afford the roots weak liquid manure freelv. 



stronger compost than before. See that the ball 

 of soil is neither too wet nor dry before turning 

 the plants out of their pots, and if the junction 

 of scion and stock has not been covered with 

 the soil, take this opportunity of covering it. 

 Newly-potted Roses should be shaded lightly 

 for a few days unless the weather is dull.

NEW ROSES OP THE N.R.S. " CATALOGUE/' 



(Continued from p. 68.) 



ROSES INTRODUCED IN 1909. 



The new edition of the N.R.S. Catalogue for 

 1912 contains 32 Roses brought out in the year 

 1909. Of these, there are 10 which were men-

Two or three slight fumigations in succession are

 small buds may fall prematurely. I have found

 Catalogue, while the remaining 22 now make their

the variety Niphetos very sensitive to injury by 

 fumigations ; not so much with respect to its 

 foliage as the flower-buds. 



Mildew is the most troublesome disease of 

 Roses, and, in spite of every care in ventilating, 

 seems to put in an appearance after any sudden 

 change of weather. Several specifics are recom- 

 mended for this disease, but although we have 

 given most a fair trial and found them more or 

 less effective, we still use the following prepara- 

 tion : — Soft soap and extract of quassia, mixed 

 with black sulphur and a little soluble paraffin. 

 This is deadly to almost all insects, as well as 

 to mildew; and it leaves the foliage clean. 

 MoEffie, used from the first and continued ac- 

 cording to directions, is one of the best of the 

 many proprietary articles used for mildew. Any 

 check to growth, such as is caused by careless 

 watering, either in extremes or by using too 

 powerful liquid stimulants, has much to do with 

 the outbreak of this disease. 



Roses enjoy plenty of light, but sometimes an 

 excess of sunshine with clear glass may cause 

 injury, and some plan should be adopted of 



appearance here for the first time, and take their 

 place in the list of new varieties. I have alreadv 

 dealt in previous articles with the new Roses of 

 1911 and 1910, mentioned in this list, and the 

 observations I have there made with regard to 

 our knowledge of these new Roses apply, with 

 some slight modifications, to the Roses I propose 

 now to discuss. 



Andre Gamon, H.T., is a good Rose, likely to 

 be useful, both for garden and exhibition. The 

 flower is rose colour with a slight shade of car- 

 mine, but not an objectionable one, and there 

 is often a slight yellow colour at the base of the 

 petals, which helps to light them up, the result 

 being a bright and pleasing flower. If not, per- 

 haps, a great Rose, it is quite likely to become a 

 popular one. It seems also to do well under 

 glass, and was well shown at the Temple Show 

 iast May. 



Beatrice, H.T., is a Tich pink. The flower 

 is well formed, and I have often expected it to 

 give me exhibition flowers, which it will do 

 occasionally, but it cannot be relied on to do so,
