How the Colorado year breaks down
Counted, not claimed
Something in the Colorado list is in bloom from March through November, and June is the peak — 32 of the 59 species are flowering then.
17 of them are caterpillar host plants and 11 support specialist bees — the ones that do the most work in Colorado yards.

Before you buy
Who this is for
Made for
- Gardeners in Colorado planting for pollinators rather than for a catalogue
- Anyone replacing lawn with something that belongs here
- New Colorado gardeners who want the timing decided for them
Not for
- Anyone wanting exotic ornamentals; every species here is native to Colorado
- Precise planting dates — Colorado timing is given as windows
Everything here describes typical timing across Colorado, drawn from long-run records — weather, elevation and how close you are to water all move the real dates around. So the Colorado 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
USDA PLANTS Database · GBIF occurrence records · Lady Bird Johnson Wildflower Center · USA National Phenology Network · The Xerces Society · Cooperative Extension (land-grant directory). How each of these is used in the Colorado edition, and which figures are measured rather than modeled, is set out in the methodology.
Questions
Before you decide
Is this specific to Colorado, or a national guide with the name swapped in?
It is built from Colorado's own data. The 59 species in it were filtered to those with verified occurrence records in Colorado and to hardiness zones 3a–6b.
Colorado spans several hardiness zones — which one does this cover?
All of them. Colorado runs 3a–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 Colorado?
It describes typical timing across Colorado drawn from long-run records, and because weather, elevation and habitat move real Colorado dates around it says "usually early May" rather than "May 4th".
Is it worth paying when the Colorado pages here are free?
The free Colorado pages are the month you are in; this is the whole Colorado year, planned before it arrives and printable, so you are not holding a screen in the garden.
Will it work for my part of Colorado, or just the big cities?
It is written at state resolution — Colorado as a whole, with regional notes where Colorado genuinely differs end to end, and nothing behind it is recorded finely enough to honestly promise more than that.
What format is the Colorado 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 Colorado pages are made to be carried outside.
What if the Colorado guide is not what I expected?
Email hello@birchcompass.com within 30 days for a full refund on the Colorado edition, and keep the files either way — asking for them back would be theatre.
Prefer to read online first? The free Colorado native plants reference covers the same ground on screen.
