Plant details
Safety first: Typical seasons only — not an ID guide. Several dangerous species mimic harmless-looking ones. Always confirm any find with an expert before doing anything with it.
🍄 Seen a species not on this list? Report the sighting
This records when and where a species was seen — not an identification or edibility claim.
Photos and expert confirmation happen off-app; this just helps track seasonal timing.
Helps confirm identification before it's added — photo is only visible during review, not publicly displayed. Still not an edibility claim.
Missouri notes: MU Extension trials found 6 cultivars perform well in Missouri: Munstead, Hidcote, Phenomenal, Grosso, Provence, and Dutch Mill.
Spanish lavender (L. stoechas) does not survive Missouri winters — one Centralia farm lost 100% of 36 plants their first winter.
All types need excellent drainage; Missouri humidity and clay soil are the main challenges. Plan for 20–25% annual plant loss per MU Extension.

Every observation improves the calendar — for everyone.
Whether you're a beekeeper, gardener, forager, or land manager, logging what you actually see in the field makes the bloom dates more accurate for your location.
You don't need to know the GDD — just pick the plant, enter the date, and add a note. The more observations logged across all users, the better the calendar gets for your whole region.
For the most precise calibration, look up the real accumulated GDD on the
USA‑NPN AGDD map ↗
(set the date, base 50°F, click your spot) and paste it in the Precise GDD field. Leave it blank and the app estimates it automatically.
⚠ Observations and notes you log are shared publicly with other users — don't include personal information in the notes.
Tapping GPS finds your nearest city and looks up elevation via an external map service.
