FAO ECOCROP
Start the season right
Plant neka simbo in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Neka Simbo prefers pH 5 to 8 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Keep it in good form
Prune neka simbo to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
Where Neka Simbo thrives
Neka Simbo is hardy across USDA zones 8 through 11. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 8–11 spans average winter lows from 10°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 1 outright and splits 27 more down the middle — and which side of that line your land sits on changes the answer.

Where Neka Simbo stands, state by state
Neka Simbo is rated for zones 8–11 — a cold floor USDA puts at 10 to 20°F. Across the 50 states and DC, 1 sits fully inside that band, the line runs through 27 more, and 23 sit outside it — and inside every split state, the same line runs on at county grain.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

How we know this about Neka Simbo
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 Neka Simbo in my zone?
Neka Simbo grows in USDA hardiness zones 8 through 11 (Rated hardy to zone 8a by NC State Extension Gardener Plant Toolbox, checked Oct 2026. Ceiling: not verified.). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Neka Simbo?
Most growers plant neka simbo after the last spring frost, once the soil has warmed. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Neka Simbo need?
Neka Simbo 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 Neka Simbo need?
Neka Simbo prefers soil pH 5 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Neka Simbo attract pollinators?
Yes — neka simbo's flowers are a solid nectar source for honeybees and native bees. We haven't confirmed this against a published source yet.
