PLANTING LIST 341 



spray with Bordeaux or ammoniacal copper carbonate, beginning 

 in May, every two or three weeks until the flowers appear, taking 

 pains to wet the under sides of the leaves as well as the upper. The 

 plants blossom through midsummer. 



Horehound: A hardy perennial herb, its leaves used in cough 

 medicines. Grow from seed, cuttings, or root divisions. Set two 

 feet by one. 



Ipomoea : This includes three different kinds of plants, morning- 

 glory, moonflower, and cypress vine,* all described in the chapter 

 on Vines. - 



Iris : This comprises several kinds of plants, some of which are 

 among the most beautiful and satisfactory perennials in the whole 

 garden, being lovely in form, delicate in color, and very easy to grow. 

 They cannot, however, be grown satisfactorily from seed; root 

 divisions are needed. Among the several kinds the chief two are : 



German Iris : A plant with a gnarled fleshy root, -preferring a 

 fairly dry situation. Its leaves are like stiff sword blades, the 

 flower stems are stout and strong, bearing several buds which open 

 one after another. The flowers are exceedingly delicate, and tear 

 easily; they last, however, well in water. The varieties are ac- 

 cording to the color and marking, which are almost as delicate and 

 numerous as those of the gladiolus. The season lasts over a fort- 

 night, with its middle about June 1st ; and by a careful choice of 

 varieties (consult the seedsman) it may be prolonged. 



Japanese Iris : Follows German Iris in season. The root is more 

 fibrous, and prefers a moist situation; the leaves are not so stiff, 

 being more grass-like ; the flower stems are not so sturdy, and more 

 gracefully bear larger and more lovely blossoms, flatter in shape 

 and deeper and purer in tone, seeming to hover like great butter- 

 flies. Colors, with many markings, range through white, lavender, 

 and blue, to purple. 



These Irises are very hardy, and the clumps increase in size, 

 from year to year, so that every three or four years they should be 

 divided. Give them about two feet of space. 



Kale : A plant of the cabbage family, which bears loose leaves,
