What you could grow (and when) in 1800

An HTML version of a chart designed by Thomas Jefferson, showing availability of produce at the Washington, D.C., market during the years he was President.

Thomas Jefferson was a man of many interests, and being President of the United States doesn’t seem to have deterred him from pursuing them. If from the White House he couldn’t putter in his beloved garden at Monticello, he still managed to keep up with the business. During his eight years in Washington, he kept track in his journal of the produce available month by month at the city market and drew up a chart showing each item’s earliest and latest availability during his residence — a fascinating, if a bit foggy and bubbly, window into early American gardening and vegetable consumption.

Because I’ll not be out-geeked by a two-centuries-dead president, I’ve made an HTML version of Jefferson’s chart. (The screen shot is above.) His handwritten original was quite clever (you can see it at low resolution on the Monticello website) and I’ve preserved the basic design while adding a bit of interactivity: for now just the ability to mouse over headings to highlight rows and columns, but eventually also to view definitions and commentary on various items of produce.

Here are a few observations, which I’d consider prompts for further research:

  1. Despite the deservedly bad reputation of most early American farmers and the technology-fired notions of “progressive” farmers in the twentieth century, some gardeners, at least, were able to grow vegetables for market over surprisingly long seasons in 1800. Lettuce, spinach, and parsley were available year-round. Cucumbers appeared as early as April. And who grows artichokes commercially on the Chesapeake at all nowadays?
  2. Clearly, then, gardeners were using some methods of season extension — hot beds and cold frames, as well as cold storage for long-keeping items like cabbages and potatoes.
  3. That said, the bars represent the longest possible season for each item; they begin with the earliest date the item appeared over eight years and end with the latest date its season ended. One early spring and one warm fall, years apart, could make some seasons appear two months longer than in any given year they actually were.
  4. Additionally, we don’t know how much of any given item was available out of its normal season (e.g. lettuce in January), or what it cost. Given what I know of early nineteenth-century hot-bed technology, it was likely quite expensive. We also don’t know what the quality was like — but given the alternative of eating root-cellared turnips and sauerkraut, I imagine people took what they could get.
  5. Some fairly obvious items aren’t listed — apples, for example. This doesn’t seem to be a complete list of produce available in Washington.
  6. Finally, it’s worth noting that Washington was a very new city in 1801; the White House wasn’t ready for occupancy until November, 1800, just five months before Jefferson was sworn in. Was there a market in Alexandria prior to 1800, and did market gardeners ramp up production when the Federals showed up? Who were these market gardeners? Were they specialists? Planters who expanded their domestic operations? Women selling vegetables and herbs on the side, along with butter and eggs?
