Comments

'Red Rothomagensis' is still in the greenhouse so no data this summer. The 'Acutiloba' cutleaf elderberry shows severe damage with only a few leaves emerging. Many limbs are dead.  

Noted on May 28, 2009 that bee balm had been cut back by a few inches so that first "true bloom date" may be off. Will record date of first bloom on existing stems.

Redosier dogwood did not have more than a few blooms.

Daylily not established in garden.

Leopardbane has not established well in garden. No data to report.
