The genus Geum is a member of the massive rose family (Rosaceae), which …

Good Foliage Amongst a Richness of Flower

Foliage First.

Philesia Navidad!

During my first tour of S. Chile in 1998, there was a single shrub I wished to see more than any other. Related to the national flower of Chile, Lapageria rosea, Philesia magellanica is less a climber and …
