THE GARDEN WEEK BY WEEK 



April pergolas, and arbours. The Common, Latifolius, and its 



I~i5 white variety, Albus, are the best known ; but there are 



several others, notably Delicatus, blush-coloured, and 



Coccineus, crimson, which may be grown by those who 



like to specialise in this flower. 



The Magnolias are perhaps used more largely for 

 borders than for walls, but Conspicua is a good wall 

 plant, and its white flowers are fragrant. 



The Victorian Snow-bush, Olearia Stellulata or 

 Gunniana, is a charming shrub for a low wall. It is an 

 evergreen, and flowers freely in summer. 



Both the Passion-flower (Passiflora caerulea) and the 

 white Constance Elliott are beautiful and interesting wall 

 plants, but they cannot be relied upon if the aspect is 

 cold, and ought to have warm, sheltered places. 



The Siik-Vine, Periploca Graeca, is a singular and 

 interesting flower of brownish red. It is hardly worthy 

 of selection as a prominent wall shrub, but may form one 

 of a collection of plants on a pergola. 



Polygonum Baldschuanicum is hampered by a 

 terribly formidable name, but British amateurs must 

 try and master it, for it is a magnificent plant, hardy, 

 climbing very rapidly, and bearing a profusion of 

 drooping white or pink sprays of blossom in summer 

 and autumn. Those who see it in full beauty on a 

 tall framework of poles in September will not readily 

 forget it. 



Roses have been dealt with already. 



The Flame Nasturtium (Tropoeolum Speciosum) has 

 many admirers, many of whom gaze at it despondently, 

 as a plant which has baffled them. It is glorious in 

 August and September where it thrives, being a sheet of 

 vermilion. A hot, dry site is fatal to it, and it is best 

 planted in a place where the roots are in the shade.
