The evening will feature a friendly cook-off competition between local restaurants organized by parents at the J.P. Manning Elementary School, a Boston public school in Jamaica Plain.

What began as a school community night has grown into a citywide event, attracting foodies in the area and support from generous sponsors. The primary goal of this event is to celebrate the restaurant community and to raise funds to support a strong curriculum for the kids and teachers who work so hard at this small public school.

Every ticket includes a slider hamburger from each restaurant, sides, desserts and one beverage (beer/wine/soda). Vegetarian options will be available. There will also be live musical entertainment and a cash bar.

Tickets are $45 or $300 for a table of eight, and can be purchased at www.burgerslam.org.

Art display

The Arnold Arboretum is displaying “Impressions of Woody Plants: Disjunction, Two Artists and the Arnold Arboretum,” copper etchings by Bobbi Angell and watercolor paintings by Beverly Duncan, in the Hunnewell Building, 125 Arborway, now through July 22.

An opening reception with the artists will be held from 1 to 3 p.m. on Saturday, May 19 and a workshop with the artists from 1 to 3 p.m. on Saturday, June 9.

Botanical artists Angell and Duncan have different approaches to their work: their media, copper and watercolor, their plant focuses, exotic and native, and their backgrounds, botany and art. In the end though, it is all about the wonder of woody plants and the artists’ approaches to creating images.

Angell is attracted to unusual, cultivated specimens due to her long history working with botanists and horticulturalists. Her drawings are developed into finely crafted copper etchings, which are then printed in limited editions.

Duncan is drawn to the familiarity of native plants. She translates the common and recognizable into intimate portraits in detailed watercolor paintings. For this exhibition, Duncan focused on paintings of seedlings, the delicate early life of a tree or shrub.

Call 617-384-5209 or send an email to arbweb@arnarb.harvard.edu for more information.
