Stock is an annual grown for its 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 moderate draw for honeybees, butterflies, and moths.

What Stock is
Stock grows as an annual and reaches around two feet at maturity. It blooms from spring through fall. It's also deer-resistant and well suited to containers.
How to grow Stock
Stock does best in full sun — at least 6 hours of direct sun a day — and soil from pH 6 to 7.5, on well-drained ground. It needs around 600 growing degree days to mature and a growing season of at least 50 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant stock in full sun with at least 6 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
Stock prefers pH 6 to 7.5 (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 stock blooms in the cool of the morning, just as they open, for the longest display.
Where Stock thrives
Whether stock thrives on a given site comes down to its soil pH, drainage, sun, and frost dates — the conditions that vary parcel to parcel.

Growing guides for stock
In rotation planning, stock counts as a Brassica — beds recover best when brassica crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)

How we know this about Stock
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 Stock in my zone?
Zone data for stock is being finalized. A Growable Ground report checks your parcel's full suitability against federal soil, climate, and zone data.
When should you plant Stock?
Stock 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 Stock need?
Stock needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Stock need?
Stock prefers soil pH 6 to 7.5, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Stock attract pollinators?
Yes — stock's flowers are a solid nectar source for honeybees, butterflies, and moths. (Source: Pollinator Partnership.)
Is Stock safe for pets?
Stock is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
