PcBonta Moutan, we all remember to I May ; the soil should be poor, dry, and 

 have passed from our stoves to the i thoroughly drained; if against a wall, 

 green-house, and now they are in our I the border should be protected through 

 open gardens. Every year renders us the entire winter by a roof of hurdles 

 acquainted with instances of plants thatched with straw, and projecting 

 being acclimatized : and, in addition to . about three feet." 



' ACHILLEA. Milfoil. Sixty-four spe- 



cies, all, except A. AUgyptica, herba- 

 ceous perennials. Common garden soil. 

 Divisio-n of roots. A. JEgyptica is a 

 green-house evergreen. Cuttings. Peat 

 and loam. 



ACHIMENES. Six species. Stove 

 bulbs. "After the plants have done 

 flowering, and the to()s die down, in 

 November, allow the bulbs to remain 

 undisturbed in the pots, laid on their 

 sides beneath the green-house st:ige, or 

 some other place where frost and wet 

 cannot reach them, where they may re- 

 main until the latter part of January, 

 then to be placed in a gentler heat, and 

 watered until the soil becomes suffi- 

 ciently moist to encourage vegetation. 

 When the small scaly bulhs have made 

 shoots about two inches in length, plant 

 them singly in small sixties, in a mixture 

 of leaf mould and a small portion of sil- 

 ver sand. At the subsequent sliifling, 

 until the plants are finally placed in six- 

 teens in June, the compost consists of 

 light rich turf loam and peat, or leaf 

 mould, when peat cannot be i)rocured 

 in equal proportions, and on no account 

 sifted. The pots are thoroughly drained, 

 a point which forms the basis of all 

 good culture, both in pots and in the 

 open ground. For growing several 

 plants in one pot, take No. 12 size, into 

 which turn five of the plants jjreviously 

 kept in sixties, placing one in the cen- 

 tre, and four round the edges. These 

 forma noble mass when in bloom ; but 

 never assume the unilbrm conical shape 



those already noticed, we find that Mr, 

 Buchan, Lord Bagot's gardener, at 

 Blithficld House, in Staflbrdshire, has an 

 old cinnamon tree (Tyiurus Cinnamo- 

 mum) under his care, which ripens seed: 

 from these many plants have been raised 

 that endure the winters of England in a 

 conservatory without any artificial lieat. 

 Then, again, there is no doubt that all 

 the conifera; of Mexico, which flourish 

 there at an elevation of more than SOOO 

 feet above the sea's level, will survive 

 our winters in the open air. Among 

 these are Pinus Llaveana, P. Teocate, P. 

 patula, P. Hartwegii, Cupressus thuri- 

 fera, Juiiiperus flacc Ida, Ahics religiosa, 

 and some others. Many natives of the 

 southern states have been gradually ac- 

 climated in Pennsylvania; experience 

 has, however, demonstrated that the na- 

 ture of the soil is all-important. On 

 sandy or light loamy land with gravelly 

 subsoil, many plants are found to witli- 

 stand the winter, which would surely 

 perish on heavy or wet land. So also 

 the aspect as regards exposure to the 

 sun, it having been found from repeated 

 observation that tender plants, espe- 

 cially if evergreen, suffer less from cold 

 when screened from the sun's rays. The 

 cause is obvious. An extensive impor- 

 tation of European Holly received at 

 the Landreth Nurseries, were, as a pro- 

 tection from the summer sun, planted 

 on the north side of a high board fence, 

 where they safely resisted the severity 

 of winter : subsequently they were 

 placed in open positions, and all were 



killed by the combined action of heat j of a single s;)ecimen. The main stem 



and cold. The following general rules 

 are the results of experiments in the 

 London Horticultural Society's Garden, 

 conducted by Mr. Gordon. 1. " Plants 

 intended to be acclimatized, should 

 never be subjected to artificial heat dur^ 



and side branches are to be neatly 

 sticked and tied out as they advance in 

 growth. The temperature of an early 

 vinery is well adapted for these plants 

 until the end of May, at which period 

 they should be taken to a cool pit, where 



ing the winter that precedes their being ! a steady moist heat can be maintained, 

 planted out; if obtained from seeds, as 1 They should be shaded in hot days be- 

 little heat as possible should be em- tween 11 A.M. ami 2 P. M., to prevent 

 ployed in raising them ; and starved or 1 the sun from scorching the foliage, and 

 stunted plants are more likely to sue- ' they should never be watered over- 

 ceed than such as have been forced into '. head. The pots should be placed upon 

 a rapid and luxuriant growth. 2. The I others, inverted, and the bottom of the 

 plants should not be committed to the 1 pit should be kept moist, closing up 

 open ground earlier than the end of early in the afternoon, and giving air in
