Societal Impact StatementCrop genetic resources, particularly seeds held in ex situ germplasm collections, have enormous value in breeding climate‐resilient crops. Much of this value accrues from information associated with germplasm accessions. Here, we argue that flavor, culinary attributes, and other traditional ecological knowledge (TEK) are important characteristics alongside genomic information and high‐throughput phenotypes. We explore both the value of this information and the potential risks of exploitation of sensitive TEK. We also examine the potential of in situ conservation to preserve not just the genetic diversity of crops, but the TEK associated with them. SummaryCrop genetic diversity is essential for meeting the challenges posed to agriculture by a rapidly changing climate. Harnessing that diversity requires well‐organized information, often held by ex situ genebanks and associated databases. However, the characterization of crop germplasm often lacks information on its cultural and culinary background, specifically its flavor or taste. For most crops, characterization data is lacking, but when it is present it is more likely to include whole genome information, high‐throughput estimation of growth characteristics, and chemical profiles indicating flavor rather than details on the dishes for which particular varieties are favored or how smallholder farms have grown particular accessions. This loss of cultural and culinary information, and the broader loss of traditional ecological knowledge (TEK), is more than just missing information. It is a loss of legacy when landraces are no longer grown by the communities that developed them. In the face of climate change, TEK has great value for developing more sustainable or resilient practices. And with increasingly global palettes, we must balance consumers enjoying dishes from new crops with the appropriation of culturally meaningful foods. Our aim here is to explore this flavor gap, to understand the risks in sharing data and the benefits of honoring long‐established uses. We emphasize the importance of ensuring the fair representation of diverse peoples in genebanks and consider both ex situ and in situ conservation approaches. Finally, we analyze the impact of modern breeding choices on culinary diversity, emphasizing the preservation of ancestral knowledge and flavor profiles. 

Flowering plants once drove a global shift in insect–plant–animal relationships and supported an increase in biodiversity, energy flux, and productivity throughout terrestrial ecosystems. We argue here that angiosperms could once again contribute to biodiversity within landscapes, if agroecosystems, and the plants within them, can be managed for multifunctional benefits. The potential for farmland to support biological diversity is understood and well-argued in the literature. We take this long-standing conversation and frame it within a longer evolutionary context, bringing attention to how modification in 2 key areas of our current food production system could support this goal. First, a move toward crop and grazing landscapes that more closely align with regional food webs can lead to observable improvements in community wildlife abundance. Second, we can re-expand the genetic base of our food, fodder, and cover crops, in particular by using crop wild relatives, through the use of wide crosses, genome-assisted selection, and participatory breeding. Agriculture as it is now widely practiced utilizes a narrow sliver of total angiosperm species diversity and within-species genetic diversity on a large amount of land. Change to this status quo requires coordination across tightly interlinked policy areas. It will also require social change. Farmers should be supported to transition through nudges throughout their social network. This necessitates a significant shift in our collective culture to value growing and consuming the flowering crops that can trigger an angiosperm revolution of the Anthropocene.
