Greenheaded Coneflower - resolved


Golly gee!  I had the grower's phone number fall into my life with
yesterday's mail.  Called, and the mystery plant is 'Ratibida pinnata' !
Related to Prairie Coneflower, 'Ratibida columnifera'.

'R. columnifera' :
Alternate leaves to 5" long, pinnately lobed into lanceolate, coarsely
toothed segments.   Bright yellow flower heads with drooping ray flowers on
long stems.  Disk is 1/2 to 1" cone.  Errect finely branched, 2-3' tall and
18" wide.  Blooms in summer.  Native to dry NA praries.  Grow in full sun,
in very well drainned soil.  Hardy zones 4-9.  Use in sunny border or
meadow.

'Ratibida pinnata' :
Taller, 3-5' with larger leaves and flowers.

Have it in full sun, but right next to the drip irrigation.  So far, so
good.
