PLANTS GROWN FOR THEIR SCENT 83 



house, and the soil is kept drenched with warm water, flowers 

 can be obtained in a few weeks. Of course in a lower 

 temperature the process is slower, but even then plenty of 

 moisture is essential. Fresh crowns should be potted every 

 year. 



Freesia. — See p. 138. 



Geranium (Scented-Leaved). — See Pelargonium, p. 62. 



Heliotrope.— See Heliotropium, p. 57. 



Hyacinth. — See p. 139. 



Lavandula vera (Lavender). — Though common enough 

 in gardens, lavender is not often grown in pots, but there is 

 no reason why it should not be. Apart from its pleasant 

 fragrance, it is supposed to keep away flies, and should, 

 therefore, be useful in a room. It needs a sunny position, 

 but in other respects its cultivation presents no difficulties. 

 It can be propagated by cuttings in autumn, or by seed. 



Lilac— See Syringa, p. 65. 



Lonicera fragrantissima — See p. 76. 



Mathiola (Stock). — For cultivation of M. hicornis (night- 

 scented stock), see Annuals in Pots, p. 27. Ten-week 

 stocks (hybrids of M. a?mua) can be grown in the same way. 

 The biennial kinds, such as the Brompton stocks (hybrids of 

 M. incn?ia\ are generally sown in August and September, 

 wintered in a cold frame or greenhouse, and kept fairly dry 

 until growth commences in spring, when they need plenty of 

 water and weak liquid manure. 



Mignonette. — As the botanical name. Reseda odoi'ata^ is 

 rarely used by gardeners, this deliciously scented annual 

 is placed here under its popular name. As a rule, the 

 object in growing it in pots is to make it flower in winter or 

 in early spring, and for this purpose warmth is necessary. 

 The soil should be firm and porous, and either bone meal or 

 basic slag should be mixed with it, or else, as some form of 

 lime is important, old mortar should be used as drainage 

 instead of the usual broken crocks. Five or six seeds should 

 be sown in pots of 3^ in., and the pots should be placed in 

 a cold frame, which should be kept shaded and close. When 

 the seedlings appear, both air and light must be admitted.
