SEASONABLE ORCHIDS. 



Trichcsma Suavis. 



'rricho^ma svia\is is not much si'cn in 

 cultivation. Iieiny rather rare. Jf is oe 

 casionally yrown as < 'icloyyne coi'onaria 

 and i^ coininonly known as the hair 

 orchid, from the crisjiy crests un the 

 disk. A native ot ihi' Kliassia ]Mo\in- 

 tains, tiicliosmas succeed liest in shal 

 low baskets in an inti'rmediate tempera- 

 ture, ')■'> t\viivi-i-^ at niylit in winter Iteinc; 

 ample. Fern root mixed with a little 

 sphafimnn is :> suitalih' compost, and the 

 plants siionld lie huny well up to the 

 light and g|•o^vn in a north house in sum- 

 niei. The lloweis. v\liich are earrii'd on 

 short racemes, i losely resemhle those of 

 ca-logynes. They are creamy white in 

 color, the tips lia\ing spots and margins 

 of lirownish crimson. The odor is very 

 pleasing. 



Ansellia Afrtcana. 



African orchids in cultivation are not 

 numerous. Ansellia Afrieana is a strong 

 growing variety, introduced in 1844 from 

 Fernando Po. Large jiots are necessary 

 for its culture. They should contain 

 ample drainage. A compost of coarse 



fern liljer and siihagimni is suitable. Lit- 

 tle water is needed in the resting season 

 and an aluindant supply while growth 

 is being made. The growths attain a 

 height of three to live feet and carry 

 light evergreen foliage. The drooping 

 (lower spikes are large, carrying tweuty- 

 ti\ (' to lOi) flowers, ami are greenish- 

 yidlow in color, spotted with Ijrownish- 

 yi'i[. They are borne on the upper part 

 of the bulbs. Ansellias re(piir(.' a warm 

 house, (id tlegrees at night in winter },ie- 

 ing as low as they should be grown. 



ANOTHER [NEW PLUMOSE FERN. 



AVliat is described ;is ''the most b(;auti 

 fill sport that has yet ajipeared in this 

 numerous family'' ot' crested ferns is in 

 the hands of Thomas K'ochford i^ Son. 

 Tuinfoid Hall Nurseries, liroxbourne. 

 Herts, the larjjcst commercial <irepiihoiise 



firm ill England. The variety was ex 

 hibited May 4, before the Koyal llorticul 

 tural Society. London, where the lioral 

 coinmittee iiuaniniously voted it an awaril 

 of merit. Tt was staged under the nann 

 .\eiihi(depis exaltata Lycopodioides. ami i- 

 said by the Horticultural Advertiser to 

 be ''an ex(iuisite iduniose form, so dense 

 and mossy in a]>[ieariince as to amply 

 merit its varietal name.'' The fronds 

 are smaller than in the case of some 

 other varieties now in coinuierce. 



DON'T RUB IT IN. 



Ill all the years that nicidiiie pii'paia 

 tioiis ha\e been used in .\nieiican gr(>en 

 houses but ime accident has been re]iorted 

 as .'I result of carelessness, but from Eng- 

 land there come fre(ju<'nt tales of death 

 and injury through ignorant use of this 

 poison. The latest cast> is from the llaiit- 

 :iiid Sussex ('ouiity I'ress of Mav ]."): 



■'Two little girls liavi' had a very nai 

 row escape from being killeil by nicotine, 

 such as is used for fiimigatino yit'en 

 houses to destroy green lly. A boy, em 

 ]iloyed at b'edlands Nursery. Kniswdrth. 

 took some such preparation home with 

 him, needless to say. witliout permission, 

 which his mother ii^ecj on the heads of 

 the iw(i little girls. liotli the children 

 bei-anie iincoiiscions very (|uickly. and 

 were for some time in a very precarious 

 condition, but thanks to the skill of Dr. 

 (d.anville. of iMiisworth. they have nov\ 

 recovcreil. We would uiLie upon Liarden 

 CIS to kee]i all such pre|ia i;it ion~ care

SEASONABLE 



SUGGESTIONS 



I 



Callas. 



With .Memorial day the calla .season 

 practically ends. 'riie llowers are now 

 only a fraction (d' their normal size, and 

 the yelhiwing of the foliage indicates the 

 ilesire id' the plants for a rest. Take the 

 (lots ((utdo(jrs and lay them on their 

 siiles. Aviiere they can get plenty of sun- 

 shine. If you have a (juantity of young 

 (dfset.-. not yet suni(dently strong to 

 llower. the bi'st 'way to strengthen them 

 is to plant outdoors in j-ich soil. They 

 will not make much growth until late 

 summer, but by the early jiart of Sep 

 leinber they will li;ive increaseil surjiris- 

 inyly in size ami strength, \vlien they 

 can be candiilly lifteil ;iiid potleil. 



Cyclamens. 



\\ ith the iiiiiiieroiis other duties al this 

 iiusy season, it is dilhcult to pidperly at 

 teiiil to the \vants of all our jilants, and 

 some are liable to be a little negl(>cted. 



The little cy(daniens will now be better 

 removed to a coldfranie, where they can 

 be stood on a bed of clean a.slies. Here 

 they will be well u]i to the light, .and can 

 get an !ibundant supply of air. Until 

 we get ■warmer and more settled weather, 

 it is inadvisable to leave the sashes off at 

 night, but on cloudy days we like to re- 

 move them for a few hours. Be sure 

 that the young plants are not allowed 

 to become matted in the ]>ots. Tf they 



I iiavc become root boiiinl. carefully loosen 

 the ball of roots with ;i pointed stick 

 when repotting them. 



Our largest jdants are now in -lij-inch 

 pots, and a smaller .size are in .1 inch. 

 For future shifts we will use a rather 

 heavier soil, one containing no leaf nudd. 

 but a mixture of librous loam, rotteil 

 cow manure and sand. It is better to 

 leave out bone and other fertilizers and 

 ajijily these in the form of toi'dressings 

 later. KCej) the surface soil loosened 

 and fumigate to keep thrijis in check, 

 b'un lath shades o\cr the jilants during 

 bright sunshine. I'ather than shade the 

 glass. 



Nephrolepis. 



\\itli .Memorial day stock out ot' tlie 

 way, many carnations jiractically iloiie 

 and more \acant gieenhoiis(> sjiacr th.'in 

 We have had I'or many months, it is po.-^ 

 sible to gi\e some attention fo increasing 

 the stock ot' nephrolepis. If a small 

 house can be given up to these, all the 

 better. If not. a side bench can be util- 

 ized to good ad\antage. ('heesechdh 

 can be tacked along the front of the 

 bench to keep the air away. Nejihiolepi? 

 do well in a good loam; a little leaf-mold 

 or decayed manure is not objectionable. 

 An aliundant crop of runners will now 

 be found on the old plants, and if these 

 are gotten in at once tliey will make nice 

 stock by fall. Of course, if this work
