Wild Heliotropes (Genus Heliotropium) 



Heliotropes are found in Florida, both as homely weeds 

 of waste places, and as attractive wild flowers of the open 

 country. One of the latter, H. polyphyllum, grows in such 

 profusion that prairies in the southwestern part of the 

 peninsula are whitened by its bloom in early spring. The 

 golden yellow flowers of H. Leavenworthii, which grows 

 chiefly in small colonies near the southeastern shores, are 

 seen in winter as well as summer. 



A shrub, Tournefortia, with short flowering spikes simi- 

 larly curved at the tips, and with an abundance of soft 

 gray foliage, grows on sea beaches, and often takes fan- 

 tastic forms.
