^ HARDY PERENNIAL PIANTS/ 



Double Hollyhock 



Hybrid Iris Interregna 



An interesting type, the result of crossing /. germanica with 

 I. pumila hybrida. They bloom earlier than the German Iris, 

 and the flowers combine perfection of form with large size and 

 clear and decided colors. The foliage is dwarf, and main- 

 tains freshness throughout the season. The flower stems are 

 almost 18 inches high, holding the flowers well above the 

 foliage. 



Fritjof . Standards lavender, falls satiny violet-blue. 

 Helge. Standards creamy yellow, falls darker, veined yellow. 

 Spectabilis. Rich, free-flowering, violet-purple. 



25 cts. each; $2.50 per doz.; $15.00 per 100. 



Iris Pumila Hybrida 



A cross between /. pumila and /. germanica. Very showy. 

 Early flowering. 10 to 12 inches high. 

 Caerulea. Very early light blue. 

 Cyanea. Rich violet purple. 

 Excelsa. Good pale lemon yellow. 

 Schneekuppe. Pure white. 



25 cts. each; $2.50 per doz.; $15.00 per 100. 



Iris Sibirica 



Orientalis. Rich, violet-blue; very free and one of the best. 

 June, 3 J feet. 



— Perry's Blue. A comparatively new variety with very 

 large, clear blue flowers on stout stiff stems, a vigorous 

 free grower and very free-flowering, one of the best for 

 cutting. 



— Snow Queen. A variety of great merit; forms an at- 

 tractive plant; flowers snow white. 



25 cts. each; $2.50 per doz.; $15.00 per 100. 



Dreer's Superb Hollyhocks 



Stately, majestic, hardy plants, from 6 to 8 feet high, which are a necessary part 

 of every old-fashioned garden, and should also find a place interspersed with shrub- 

 bery, as clumps on the lawn or in the mixed border, where their colossal spikes of 

 bloom produce bold and showy effects, which cannot be secured with any other 

 flowering plant. 



The Hollyhock requires a deeply dug, well-drained soil, enriched with thoroughly 

 decayed manure, and should be liberally supplied with water during dry weather. 

 A slight protection throughout the winter will be beneficial. An occasional spraying 

 with Bordeaux mixture, which should be applied early in the growing season, usually 

 prevents the disease, which is prevalent in some localities. We offer the best 

 Double, Fringed and Single sorts under: 



Double Red Double Rose Double Maroon 

 Double White Double Yellow Double Mixed 

 Allegheny. Mammoth flowers, wonderfully formed of loosely arranged fringed 



petals. The colors vary from the palest shrimp-pink to deep red. Mixed colors 



only. 



Single. Many prefer the single-flowering Hollyhocks. They are usually of freer 

 growth than the doubles, and present a very handsome appearance when covered 

 with their artistic blossoms. We can supply the singles in mixed colors only. 

 Any of the above, 25 cts. each; $2.50 per doz.; $18.00 per 100. 



IberiS (Hardy Candytuft) 



Sempervirens. Most desirable dwarf plants (8 to 10 inches), with evergreen 

 foliage, which is completely hidden by dense heads of pure white flowers early 

 in the spring. 



— Little Gem. A perfect gem of very dwarf habit, not over 6 inches high with 

 masses of white flowers, in May; a most valuable rock plant. 



— Snowflake. A grand variety, 6 to 8 inches high, having exceptionally large 

 and pure white flowers, and borne in great masses during May and June. 



25 cts. each; $2.50 per doz.; $15.00 per 100. 



InCarvillea (Hardy Gloxinia) 



Delavayi. An interesting and showy plant for the hardy border, producing large 

 gloxinia-like, rose-colored flowers on 15 to 18 inch high stems during June and 

 July. Succeeds either in sun or shade, but should be well protected with leaves or 

 litter during the winter. 30 cts. each; $3.00 per doz. 



Iris Tectorum 



This is frequently referred to as the "Roof Iris" of Japan where it is grown on 

 many thatched roofs of the cottages. A beautiful species from Japan and China 

 which, while it has proven hardy as far north as Philadelphia, should be carefully 

 protected with leaves during winter; 12 inches high flowering during June. 



Tectorum. Delicately crested flowers of a beautiful shade of 



blue. 25 cts. each; $2.50 per doz.
