Bacopa is an annual grown for its white blooms, which open from spring through fall. Notably, it shrugs off deer and grows just as well in a container as in the ground. Its flowers are a modest draw for honeybees.

What Bacopa is
Bacopa grows as an annual and reaches around 6 inches at maturity. It blooms white from spring through fall. It's also deer-resistant and well suited to containers.

How to grow Bacopa
Bacopa does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.5 to 6.5, on well-drained ground. It needs around 1,000 growing degree days to mature and a growing season of at least 60 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant bacopa in part sun with at least 4 hours of direct sun. It grows in the cool halves of the year, so sow it in spring or late summer rather than waiting for midsummer heat. We haven't confirmed this against a published source yet.
Match the soil
Bacopa prefers pH 5.5 to 6.5. We haven't confirmed this against a published source yet. A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. We haven't confirmed this against a published source yet. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at its peak
Cut bacopa blooms in the cool of the morning, just as they open, for the longest display.
Where Bacopa thrives
Whether bacopa thrives on a given site comes down to its soil pH, drainage, sun, and frost dates — the conditions that vary parcel to parcel.

Your land is one point inside Bacopa's range
This page resolves to the species. Your state page draws the county line, and a report reads the parcel — the soil pH, drainage, sun, and frost dates on your exact ground, which no species average can see.

How we know this about Bacopa
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Bacopa in my zone?
Bacopa is grown as an annual, so a hardiness zone does not decide it — its growing season follows your last and first frost dates. Soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Bacopa?
Bacopa is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Bacopa need?
Bacopa does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. We haven't confirmed this against a published source yet. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Bacopa need?
Bacopa prefers soil pH 5.5 to 6.5, on well-drained ground. We haven't confirmed this against a published source yet. Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Bacopa attract pollinators?
Yes — bacopa's flowers are a modest nectar source for honeybees. We haven't confirmed this against a published source yet.
