The Evening Primrose (^nothera biennis) deserves 

 a place from its fragrance ; and it is as well to 

 sow it in some out-of-the-way spot. It often covers 

 waste building ground in London. 



Next we have the Loosestrife (Lythrum Salicaria), 

 a water-side plant, abundant in many parts of Britain. 

 There is a variety of this plant known in gardens 

 by the name of L. roseum superbum, which should

 (Herniaria glabra) and Scleranthus perennis are two 

 very dwarf green spreading plants, found in some 

 of the southern and central counties of England, 

 and which give a neat Lycopodium-like effect in 

 the rock-garden. 



Then we come to the Roseroot (Sedum Rhodiola) 

 and the tribe of pretty stonecrops (Sedum), every one of

 cottages and abundantly in many parts of Britain, on 

 rocky places, to that httle gem for a wall, Sedum dasy-

 The Orpine or Livelong (Sedum Telephium) is also 

 a fine old plant of this order. If you have any old walls 

 or buildings, try and estabhsh a few of the smaller kinds 

 on these ; it is interesting to have rare plants established 

 in such places, and that the tenderer kinds will always 

 survive on walls ; whereas they may get cut off by the 

 winter on the ground. Fern-growers find it difficult to
