BEDDING PLANTS. 



Notes on propagatiug and culture ffi)ni 



paper read before Detroit Florist Club, 



ty R. W. Unger. 



Phlox, verbena, zinnia, antirrhinum, 

 delphinium, pentstemon, nicotiana, 

 etc., should be shown about the last 

 week in March, in cold frame, with 

 just enough manure to keep frost out. 

 Sow them in a good rich soil, with. a 

 top mixture of sand, as this will keep 

 the soil sweet and prevent the seed- 

 ling from damping off during moist 

 and cloudy weather. In this way the 

 seedling, with a cool bottom, sown 

 rather thin, can stay until time for 

 planting arrives, without extra trans- 

 planting; that is, if the seed is sown 

 too thick, it is well, or rather neces- 

 sary to transplant into another bed 

 in order to keep, them dwarf and 

 healthy. 



Ricinus can be sown singly in small 

 pots and transplanted as desired. 

 Oxalis should be sown in flats, about 

 the end of March or beginning of 

 April, and transplanted as need be. 

 Centaurea gymnocarpa and candidls- 

 sima and Cineraria maritima, should 

 be sown as early as December, on ac- 

 count of their slow growth. As soon 

 as they are up, transplant and keep 

 In a cool house if possible, on a shelf 

 near the glass. About February, 

 plant into small pots, and as soon as 

 possible transfer to the hot-bed. 



Begonia Vernon is also best grown 

 from seed. Sow in flats about Febru- 

 ary, and transplant as soon as pos- 

 sible and keep in warm house. It is 

 rather tedious to first transplant be- 

 gonias on account o£ their smallness, 

 but the sooner this is done, the better 

 is is for the seedling. When large 

 enough, plant in small pots. 



Alternanthera it Is best to overwin- 

 ter in old plants; about March, pull 

 them apart and plant on warm bot- 

 tom in hot-bed, and as soon as the 

 young growth starts, cutting can be 

 had in abundance. These can be 

 stuck in a sandy hot-bed where they 

 will grow freely and also can be 

 easily used for bedding right out of 

 the frame. 



Geraniums are best propagated in 

 fall or during winter, so as to get 

 plants of proper size. Coleus should 

 "be kept in a rather warm house dur- 

 ing winter; about the beginning of 

 April, cuttings can be made. With a 

 nittle bottom heat, they will root 

 freely and will make about the right 

 sized plants for bedding. 



Sedum and mesembyanthemum can 

 le made at any time during winter. 

 Echeveria should be taken up in fall 

 and whatever young plants there are, 

 •should be taken off and planted in 

 flats. Keep them in a dry, cool place 

 during winter and increase watering 

 as the season advances. Stevia, Ian- 

 tana, gnaphalium, cuphea, ageratum, 

 salvia, heliotrope, etc., can be propa- 

 gated at any time after February. 

 Canna bulbs should be kept in a dry, 

 cool place. About March the bulbs 

 can be divided and laid in sand; when 

 rooted, plant in pots ready for plant- 

 ing. Dahlias are treated about alike, 

 only need not be started as early. 

 Caladium esculentum bulbs are kept 

 best in sand in a warm house and 

 started about April. 



HERACLEUM MANTEGAZZIANUM. 



(Translated from JloUer's Deutschi^ Gart- 

 ner Zeitung, by G. Bleiolien.) 



In Heracleura Mantegazzianum we 

 possess a biennial foliage plant, which 

 is perhaps the best and the largest 

 of its kind. It comes from the Cau- 

 casus and is best used as a solitary 

 plant upon a lawn in a half-shady 

 place in which location it will also 

 thrive best. 



If heracleum is planted as a one- 

 year-old seedling it attains a height 

 of fully two feet, its foliage appearing 

 nicely serrated and with a dark metal- 

 lic gloss. In ornamental effect the 

 plant may be compared to a large 

 acanthus. 



In the second year this plant will 

 reach maturity and attain a height 

 of about ten feet, measuring in cir- 

 cumference about eight feet. It should 

 bear a flower stalk with twenty or 

 more cream-colored flower clusters. 



(The original of the photograph 

 shown in Moller's D. 9t. Ztg, had, it 

 is stated, twenty-four such clusters, 

 each a foot in diameter.) 



Heracleum Mantegazzianum, like all 

 of its class, dies down slowly after 

 flowering at the end of August; this 

 may be one objection to its general 

 culture, but may be a little averted, 

 if the flower stalk after the wilting of 

 the clusters is cut off. 



PITTSBURG NOTES. 



The display of spring flowering 

 plants at the Phipps Conservatories 

 continues to attract large crowds daily. 

 On Sunday, April 21, 25,000 people vis- 

 ited the greenhouses. The cool weath- 

 er since Easter has been favorable to 

 the flowering plants. Many plants 

 have been kept in reserve, and 

 although the display is not quite so 

 good as on Easter Sunday, the green- 

 houses are well worth a visit. 



At the Lauchlan place many altera- 

 tions and improvements are being 

 carried out. A large cave for winter- 

 ing bay trees, hydrangeas, etc., is be- 

 ing built. Some fine specimens of 

 dwarfed Japanese evergreen trees sup- 

 posed to be 150 years old have just 

 been received. The palm house, be- 

 sides some fine specimens of palms, 

 contains a choice assortment of trop- 

 ical plants. There is also a large 

 plant of Philodendron pertusum (bread 

 fruit tree) in fruit. Mr. Price, the 

 head gardener, is an orchid enthusiast, 

 and has some good things in the or- 

 chid line. The greatest treasure is a 

 plant of Laelia lobata in a 30-inch pan. 

 This plant, which is probably the 

 largest Laelia lobata in this country, 

 has about fifty leads, each of 

 which is showin.g a flowering 

 sheath. Last year the plant had 

 over eighty flowers. At the Barns- 

 dale place, one of the finest places 

 in the npighbf)rhood tor shrubs 

 and hardy plants, Mr. Lily is making 

 extensive alterations and planting 

 hardy flowering shrubs. Large groups 

 of hybrid rhododendrons have win- 

 tered well. J. H.
