How the Iowa year breaks down
Counted, not claimed
Something in the Iowa list is in bloom from March through November, and June is the peak — 24 of the 51 species are flowering then.
17 of them are caterpillar host plants and 20 support specialist bees — the ones that do the most work in Iowa yards.

Before you buy
Who this is for
Made for
- Someone who wants the whole Iowa year in one place, planned ahead
- Households where more than one person goes outside
- Anyone who would rather print it once than look it up twelve times
Not for
- Anyone who only ever needs one month — the free Iowa pages already do that well
Everything here describes typical timing across Iowa, drawn from long-run records — weather, elevation and how close you are to water all move the real dates around. So the Iowa pages say "usually early May" and never "May 4th", which is not hedging but the most the data can honestly carry.
Where it comes from
Compiled from
USGS Breeding Bird Survey · State fish & wildlife agencies · USA National Phenology Network · Lady Bird Johnson Wildflower Center · The Xerces Society · USDA PLANTS Database · GBIF occurrence records · USDA Plant Hardiness Zone Map · Cooperative Extension (land-grant directory) · International Meteor Organization. How each of these is used in the Iowa edition, and which figures are measured rather than modeled, is set out in the methodology.
Questions
Before you decide
Is this specific to Iowa, or a national guide with the name swapped in?
It is built from Iowa's own data. Every chapter is Iowa's — its species, its timing, and garden notes for every zone from 4a–6b.
Iowa spans several hardiness zones — which one does this cover?
All of them. Iowa runs 4a–6b, and the guide carries each zone's timing rather than picking one and hoping it fits your garden.
How accurate is the timing for Iowa?
It describes typical timing across Iowa drawn from long-run records, and because weather, elevation and habitat move real Iowa dates around it says "usually early May" rather than "May 4th".
Is it worth paying when the Iowa pages here are free?
The free Iowa pages are the month you are in; this is the whole Iowa year, planned before it arrives and printable, so you are not holding a screen in the garden.
Will it work for my part of Iowa, or just the big cities?
It is written at state resolution — Iowa as a whole, with regional notes where Iowa genuinely differs end to end, and nothing behind it is recorded finely enough to honestly promise more than that.
What format is the Iowa edition, and can I print it?
A PDF laid out for both Letter and A4, one page per sheet — printing it is the point, since the Iowa pages are made to be carried outside.
What is the weekly Iowa note, and does it stop?
One short email a week through 2027, built from this same Iowa data — what to look for that week. It runs the edition year, then stops; it is not a subscription and there is nothing to cancel.
What if the Iowa guide is not what I expected?
Email hello@birchcompass.com within 30 days for a full refund on the Iowa edition, and keep the files either way — asking for them back would be theatre.
Every month of this book has a free page on the site — start with the Iowa guide. The book carries every zone's garden notes; the page only ever shows you yours.
