GALTONIA, SUMMER HYACINTH (Hyacinthus candicans). 3 ft. A 

 very beautiful bulbous plant bearing racemes of large fragrant droop- 

 ing white flowers. It needs protection in winter. Can be raised from 

 seed, but it is better to propagate by offsets. Requires moist rich leaf 

 mold. Very late in June or early July. 



GARDEN HELIOTROPE (Valeriana officinalis). 5 ft. An attractive 

 herb with large cut pinnate leaves and broad flat heads of small lilac- 

 white flowers that are deliciously fragrant; the root also has a pleasant 

 aromatic odor. It can easily become a pest because of its vigorous

 this account.

 out when once established. Thrives best in rich soil and partial shade.
