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.
Match the soil
Bacopa prefers pH 5.5 to 6.5 (Growable Ground Plant Database). 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. 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.
Good to know
Good news for pet owners — bacopa isn't known to be toxic to dogs or cats. (Source: ASPCA.)
Bacopa offers low value to bees and other pollinators.
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.

Frequently Asked Questions
Can I grow Bacopa in my zone?
Zone data for bacopa is being finalized. A Growable Ground report checks your parcel's full suitability against federal soil, climate, and zone data.
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. 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 (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Bacopa attract pollinators?
Yes — bacopa's flowers are a modest nectar source for honeybees.
Is Bacopa safe for pets?
Bacopa is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
