An informal group independent of Sarah P. Duke Gardens, the Durham Garden Forum meets once a month to enrich its members’ gardening knowledge and skill. This month, we'll consider the reasons to promote the use of native plants. Is it actually a useful concept, considering that none of us is traveling back in time to 1490? Join a panel discussion with many viewpoints to help sort out the native vs. exotic debate. Sponsored in partnership with N.C. Cooperative Extension: Durham County Center. Location: Doris Duke Center. Forum members free with annual $25 membership, payable to Durham Garden Forum.
