BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Erigeron lanatus | Wooly Daisy 



GENERAL BOTANICAL CHARACTERISTICS : 
Wooly daisy is a native perennial autotrophic forb which grows up to 2
inches (5 cm) high.  It has loosely, long-wooly, villous leaves up to
1.2 inches (3 cm) long.  The solitary heads are densely white wooly, and
the rays are pale purplish [2,11].


RAUNKIAER LIFE FORM : 
   Hemicryptophyte


REGENERATION PROCESSES : 
Wooly daisy reproduces sexually by pollination and fertilization and
dispersal of the resulting seed [3].


SITE CHARACTERISTICS : 
Wooly daisy is found in the high mountains on open, rocky, alpine
slopes, often on limestone talus.  It is common above timberline at
7,500 to 9,000 feet (2,420-2,900 m).  It grows with Siberian aster
(Aster sibiricus) and starwort (Stellaria americana) [2,6,9,11].  In the
Yukon, wooly daisy was found on a steep, scree, alpine slope at 4,200
feet (1,355 m) [9].  It occurs in Colorado at 12,800 to 13,00 feet
(3,900-3,960 m) [3].


SUCCESSIONAL STATUS : 
NO-ENTRY


SEASONAL DEVELOPMENT : 
Wooly daisy flowers in July and early August [6].
