Tagetes erecta-African, American Marigold. As usual these did well in Fargo despite the heavy rain in June. 'Perfection Orange' and 'Perfection Yellow' received high marks during both evaluation times in Fargo. The Dickinson cultivars looked better in July; by August dead heads were detracting from their overall appearance and spider mites were present, causing some yellowing and loss of vigor.
