Come! Ms. Dunlap will give two talks at the CNPS Conservation Conference Feb. 1-3 in LA!

One regarding a database of 3,700 nectar plants (& how to collect images to benefit pollinators), and the other regarding
a prototypical key incorporating a novel plant identification system that produced an order of magnitude improvement.

Filipendula ulmaria, a Rosaceae also known as MEADOWSWEET or DROPWORT, has many fine qualities including its use as a 'strewing' plant – a plant strewn about the floor to provide a natural room deodorizer. A European and Western Asia native, it is edible and is used as flavoring. This plant thrives in Zones 3-9, blooms in summer, grows in sun or part shade, and can become a towering 6 1/2 feet tall and wide. It prefers regular to moist watering in well drained soil.

In addition to the butterflies that feed on plants in the Rosaceae family (listed on the left), Filipendula ulmaria in particular attracts Satyrium calanus, BANDED HAIRSTREAK.
