The new Rudheckia laciniata "Golden 

 Glow" is a moisture loving plant. It will 

 soon be in bloom. A good watering now 

 and then will help it. 



The common sweet briar grown to a 

 single stem eight to ten feet high, and 

 supported by an iron rod, is very effective 

 when in bloom or in berry. 



The new rose President Carnot is 

 proving to be a splendid summer bloomer. 

 Some of the stock sent out is budded high 

 on Rosa canina, so look out for wild 

 growth. 



Witch-hazel.— Replying to J. R. C the 

 extract of witch-hazel, or hamamelis 

 (often called Pond's extract) is prepared 

 from the bark of Hamamelis virginiana, 

 a native, and probably the one you have 

 on your grounds. 



Clematis Madame Edouard Andre is 

 nearly as free a bloomer as Jackmanni and 

 of which it is a hybrid, and seems as free 

 from disease. It is not, however, as tall 

 a grower. This clematis was introduced 

 to this country at the time of the World's 

 Fair, where a few plants in front of the 

 woman's building attracted considerable 

 attention by the carmine red of its 

 flowers. 



The California crop of sweet pea seed, 

 now being harvested, shows a considera- 

 ble shortage owing to a somewhat un- 

 favorable season for sweet peas. 



Don't forget to start your biennials 

 soon for next year's blooming. Foxgloves, 

 Canterbury bells, mulleins, etc. At the 

 same time start some new perennials. 

 They can be tended to at the same time 

 and you thus add to the list of your gar- 

 den friends at but little cost. 



There is but little difference in the size 

 and appearance of plants of Semple's 

 asters sown underglass and transplanted 

 and those sown out-doors and trans- 

 planted. The former may bloom a few 

 days earlier. Moral, save the hotbed 

 space for other material. 



In 1895 and 1896 some Lilium candidum 

 that were badly diseased were taken up 

 about the middle of July and soaked for 

 six hours in a solution of sulphate of cop- 

 per, one ounce to one gallon of water. 

 They were then most thoroughly washed 

 with the hose and at once planted. All 

 seem free of the disease this year, and 

 over four-fifths bloomed. 



Delphinium chinense is a charming 

 garden companion, greeting us in many 

 colors ranging from the purest clear blue 

 through all its shades to a creamy white. 

 It is not a strong grower, being even 

 under good cultivation but three feet 

 high. It commences bjooming in July 

 and continues some ten or more weeks. 

 It is a good cut flower and when thedeep 

 blue form is used in connection with 

 Coreopsis Drummondii the effect is ele- 

 gant. 



The Nomenclature Committee of the 

 Society of American Florists wishes 

 information of any cases of misnaming, 

 renaming or nomenclature entanglements 

 relating to decorative plants handled by 

 the American trade, that they may be 

 incorporated in its report to the society 

 at the meeting in August. Reportsshould 

 reach the committee by August 1. Prof. 

 Win. Trelease, Director of the Missouri 

 Botanical Garden, St. Louis, is chairman 

 of the committee. 



We have received from H. H. Berger & 

 Co., New York, a copy of their book of 

 colored plates of Japan lilies, thirty sorts, 

 all lite size. It is certainly a work of art 

 and of very great interest. The rare 

 varieties of the auratum are of remarka- 

 ble beauty. Evidently Japan supplies 

 many beauties in plant life with which 

 we are yet to become thoroughly familiar. 

 Messrs. Berger & Co. also send us native 

 Japanese paintings on rice paper of ama- 

 ryllises, all of which are very beautiful 

 and will undoubtedly prove valuable. 

 The price of the book of lilies is $2 50. 



The work of extending and improving 

 the Missouri Botanical Garden, St. Louis, 

 is now actively under way. An addition 

 of one hundred acres has been made and 

 is now being laid out in accordance with 

 plans prepared by Frederick Law Olm- 

 sted. At present the number of specimens 

 in the garden is about 5,000 and the 

 addition will bring the total up to about 

 25,000, the plans contemplating an 

 entire remodeling of the garden. When 

 completed the Missouri Bota ical Garden 

 will rank with the famous botanical gar- 

 dens of the old world. Prof. Wm. Trelease 

 is director. 



Wintzer's new canna "Gloriosa" is an 

 acquis tion. The plant is very dwarf but 

 still a strong grower, thus promising a 



continuity of bloom. The spike is large 

 and full, the flowers a rich crimson 

 strongly bordered with yellow. It is one 

 of the coming cannasforthe outer border. 

 Brilliant, another canna of his 1897 set, 

 is promising well. The three larger petals 

 are a pure yellow in color, very slightly 

 dotted with crimson, the dots so small as 

 not to be noticeable a few feet away. The 

 small drop petal is a crimson at the base, 

 gradually developing into stripes on a 

 yellow ground. The effect at a distance 

 is that of a yellow canna. So far the yel- 

 low stands the sun remarkably well. 

 California is the best pure orange yet 

 produced, and is a free bloomer. 



The blister beetles, both black and 

 striped, are especially fond of Clematis 

 paniculata and C. grareolens. They are 

 early risers and hungry for breakfast. 

 Appearing suddenly in swarms it does 

 not take them long to defoliate large 

 plants. They multiply rapidly and soon 

 after their appearance, therefore it is best 

 to fight them at the start, which is best 

 done by shaking them into a wide pan 

 containing some water and kerosene oil. 

 The oil floats on the top and is death to 

 the bather. The ordinary poisonous 

 insecticides dusted on the leaves have but 

 little effect. A strong spraying with a 

 hose will drive them into your neighbor's 

 garden but the said neighbor soon learns 

 the trick, and after they have increased in 

 numbers, he gets out his hose and returns 

 them to you with compound interest, 

 therefore it is best to kerosene them. 

 They are apt to appearimmediately after 

 a hot spell late in June or early July. 



The Greenhouse. 



ERICA GflVENDISHH. 



Among the erica family proper, are to 

 be found the gems of the floral kingdom. 

 There are probably less insignificant 

 species, especially hybrids, in this genus 

 than in any other genus of the same 

 magnitude, therefore it is no easy task to 

 single out one variety eclipsing all others 

 for its superior majesty and beauty. 



Personally, outside this noble Erica 

 Cavendishii I would be inclined to award 

 the superior beauty to some one of the 

 ventrieosa section of the genus, but the 

 uncommon color obtained in the flowers 

 of Cavendishii commands respect and 

 admiration at once and therefore it can 

 be given without hesitancy the premier 

 position in the heath family for gorgeous- 

 ness, its rich yellow flowers associating 

 well with its light green foliage. Con- 

 trary to what might be supposed from 

 the unusual color already mentioned, itis 

 not difficult to grow, but is among the 

 easiest, and is one of the most robust of 

 the greenhouse varieties. 



A cool temperature ranging from 38° 

 to 45° at night will suit them perftctly. 

 The soil best adapted for ericas is good 

 fibrous loam and peat, not muck from 

 swamps, but upland peat found on the 

 mountain side; they can be successfully 

 grown, however, by the substitution of 

 good leaf soil, which partakes more or 

 less of the nature of peat, and therefore 

 ought to be liberally supplied in the soil. 

 with an addition oi a good quantity of 

 clean sharp sand. 



They must be carefully watered at all 

 times, never allowing them to become 

 dust dry to cause wilting, for they will 

 refuse to recuperate from such treatment.
