trees or shrubs. They will be in full flower while quite 

 leafless in January or February. Mollis is one of the best 

 species, and its yellow flowers with twisted petals are 

 deliciously perfumed ; its foliage is hairy. A variety of 

 H. Japonica called Zuccariniana is becoming popular ; 

 it has lemon-coloured flowers. The Witch Hazels will 

 thrive in suburban gardens. 



Notes on the best Sun Roses (Helianthemums) will be 

 found in chapter vi. These beautiful little shrubs are 

 splendid for dry spots in the rock garden. 



Hibiscus Syriacus, the Rose Mallow, is referred to 

 under Althaea frutex. 



The Sea Buckthorn, Hippophas rhamnoides, may be 

 noted for planting close to the sea. 



A splendid Hydrangea for sheltered places is paniculata 

 grandiflora, which in moist, peaty soil makes a large bush 

 that is covered with white flowers in spring. The old 

 species hortensis is not perfectly hardy, although it is 

 used out of doors in some districts, and in an ironstone 

 soil gives blue flowers. Mariesii and Veitchii are two good 

 varieties of it. 



The St. John's Worts (Hypericum) are mostly in 

 demand for covering large areas on shallow soils, where 

 better plants will not thrive. For this purpose calycinum 

 is one of the best, and its yellow flowers are large and 

 bright. Moserianum, a hybrid, is a better garden plant. 



The Kalmias may be mentioned as shrubs which 

 thrive under the same conditions as Rhododendrons, 

 liking peaty and disliking limestone soils. Glauca, a 

 small deciduous shrub, is the best known, but latifolia is 

 a much finer plant, and is evergreen. 



The Kerrias should be remembered, particularly the 

 double form of Japonica, which produces its yellow 

 flowers in abundance. There is a variegated-leaved
