Richardia. The Arum Lily (Richardia 

 aethiopica) is a universal favourite, the large 

 white trumpet-shaped flowers with yellow 

 spadix being much appreciated, either in 

 a cut state or on the plant. There are 

 some distinct varieties, notably The Godfrey, 

 unusuallv free-flowering, and Little Gem. 

 quite a miniature kind, the flowering stem 

 being little more than a foot in height. 

 There are two quite distinct ways of growing 

 Richardias in order to have them in flower 

 during the winter months: The first is to 

 plant them out in rich, well-prepared ground 

 in summer, and carefully lift and repot them 

 in the autumn ; afterwards they must be 

 kept close and shaded until the roots 

 recover from the check of removal. The 

 other method is. after the plants have gone 

 to rest late in spring, to lay the pots on their 

 sides and allow the soil to become quite dry ; 

 then towards the latter part of July shake 

 the dormant roots clear of the old soil, and 

 repot in some good turfy compost. Little 

 water is given at first, but the supply is in- 

 creased as the plants grow. They may be 

 kept out-of-doors until autumn. As the pots 

 get full of roots fertilisers will be beneficial. 

 Much interest has of late been taken in the 

 yellow- flowered Richardias, the best of which 

 are Elliottiaiia and Pentlandii, rich vellow,

and Mrs. Roosevelt, sulphur. These have 

 flattened tubers, which pass the winter in a 

 dormant state. They must be potted in 

 spring and placed in the warmest part of the 

 greenhouse. As the spathes develop they 

 need a liberal amount of water. The flowers 

 are borne in summer. After they are over 

 the plants should be watered as before until 

 the leaves turn yellow, when they must be 

 allowed to get quite dry, in which condition 

 they will remain until spring.

Salvia. Several members of the Sage 

 family are of considerable value for green- 

 house decoration, especially those which 

 flower during the autumn months. Among 

 them are S. splendens and its varieties, with 

 scarlet flowers ; S. azurea grandiflora, also 

 known as S. Pitcherii, blue ; S. Bethelii, pink, 

 and S. rutilans (the apple-scented Salvia), 

 scarlet. Cuttings of the young shoots form 

 roots readily in spring, and the plants grow 

 freely if given the same treatment as 

 Chrysanthemums,
