How to Grow Pimento Peppers: The Heart-Shaped Sweet Pepper That Needs 95 Days to Turn Red, Why Its Walls Are Thicker Than a Bell’s, and the Roasting-Ready Harvest Window
Grow pimento peppers from transplant to full red in about 95 days. See why their walls run thicker than a bell’s, and exactly when to harvest for roasting.
A pimento is not just a red version of a bell pepper. It is a distinct group of heart-shaped Capsicum annuum cultivars bred specifically for thick, sweet flesh and a small seed cavity — the traits that make it the standard filling for stuffed olives and the base of pimento cheese. Named cultivars like Truhart Perfection and Pimiento L run about 95 days from transplant to full red, roughly two weeks past a fast-maturing bell pepper, and that extra time on the vine is what builds the wall thickness a bell pepper never quite matches [1][2][3].
This guide covers what actually separates a pimento from a bell pepper, the day-by-day timeline from transplant to red, the growing and feeding schedule pimentos specifically need, a six-point diagnostic table for common problems, and a side-by-side comparison of five pimento and cheese-pepper varieties worth growing.
What Sets a Pimento Apart from a Bell Pepper
A true pimento is bred for two traits a standard bell pepper is not: a smooth, heart-shaped fruit and unusually thick flesh relative to its size. Breeding records from NC State’s pepper program describe Truhart Perfection (Georgia Agricultural Experiment Station, 1943) and Pimiento L (1968) in nearly identical terms — thick fruit wall, heart-shaped, uniform — while a 1990s hybrid, Pimiento Elite, was bred specifically to keep that thick wall on a plant that matures about a week faster than older open-pollinated pimentos [2].
Wall thickness is the trait growers and seed breeders consistently flag as the pimento’s defining feature, though it has not been measured against bell peppers in a controlled study we could find — treat it as strong grower consensus rather than a lab-verified number. What is documented is the small, compact seed cavity: pimentos are bred to be almost solid flesh, which is why a jar of stuffed olives uses a pimento strip and not a scrap of bell pepper. Cut a ripe pimento open next to a bell pepper from the same bed and the difference is obvious at a glance — I had to look twice to find the seed cavity in mine, where the bell pepper’s hollow center is impossible to miss.

The 95-Day Countdown to Red
Expect a pimento to reach full red about 95 days after transplanting, give or take a week depending on the cultivar. That figure comes from combining two data points: named pimento cultivars reach mature green at 73 to 80 days from transplant, and University of Maryland Extension’s research on pepper ripening shows fruit needs another 2 to 3 weeks after green maturity to finish coloring [3][6].
Faster-maturing bell pepper cultivars can reach green maturity in as little as 70 days, which is why our bell pepper ripening guide often lands a full red bell closer to 84 days — pimentos, running toward the slower end of the same window, typically take about two weeks longer to finish the same green-to-red transformation. The mechanism is identical in both: as the fruit matures, chlorophyll breaks down and the green chloroplasts inside each cell convert into chromoplasts, structures that manufacture the red and orange pigments (capsanthin and capsorubin) that give a ripe pimento its color. Heat interferes with the same clock pimentos run on — evening temperatures above 75°F slow or stop pod production altogether, which is why a pimento planted for a mid-July target date in a hot climate should be started several weeks earlier than the calendar suggests [3].
| Stage | Timing from Transplant | What’s Happening |
|---|---|---|
| Green maturity | 73-80 days | Full-size fruit, walls firm, still green |
| Color break | ~80-90 days | Chloroplasts begin converting to chromoplasts; first orange blush |
| Full red | ~90-101 days | Capsanthin and capsorubin fully developed; peak sweetness |
Planting and Spacing a Pimento Correctly
Give pimentos more room than a standard pepper: 18 to 24 inches between plants in the row, with rows spaced 42 inches apart, compared to the 12-inch spacing and 3-foot rows recommended for typical bell and hot peppers [1]. Pimento plants grow noticeably more vigorously than compact bell pepper varieties, and crowding them cuts airflow through the canopy right when fruit is bulking up and most vulnerable to fungal problems.
Start seed indoors 8 to 10 weeks before your last frost date, then don’t transplant until soil has warmed to at least 65°F — pepper roots simply stall below that threshold and won’t establish [3]. For the general transplant timing and the 70-90 day baseline that applies to peppers as a category, see our pepper growing guide. Set transplants in well-drained, loamy soil with a pH of 6.0 to 6.8, and hold off on that first flower bud — many growers pinch the earliest bloom to redirect energy into root establishment before letting the plant set fruit.
Gardeners in the Deep South and other zone 8-10 regions can transplant several weeks earlier than gardeners in zone 5-6, but the 95-day countdown to red still runs from whenever the transplant actually goes in the ground, not from the calendar date. A grower who sets plants out in April in South Carolina and one who sets out in late May in Ohio should both count roughly the same 95 days forward from their own transplant date, adjusting for the heat-related flower drop above 75F nights that hits Southern gardens harder in mid-summer.
A pimento’s vigorous root system and 42-inch row spacing make it a poor container candidate compared to a compact bell pepper cultivar. Growers working with patio containers or raised beds under 3 feet wide generally get better results from a dwarf sweet pepper variety and save the pimento for open ground.
Feeding, Watering, and Avoiding Blossom End Rot
Sidedress with calcium nitrate (15.5-0-0) at a rate of 5 pounds per 1,000 square feet, applied 3 to 4 weeks after transplanting and repeated 3 to 4 weeks after that [1]. Because pimentos carry fruit longer than a fast bell pepper, growers commonly add a third sidedress application partway through fruit development rather than stopping at two [6].
Consistent soil moisture matters more for pimentos than for most vegetables because of how calcium moves through the plant. Calcium travels through the plant dissolved in water, not as a mobile nutrient the plant can redirect on demand — so a dry spell followed by a heavy watering doesn’t just stress the plant, it physically interrupts calcium delivery to the fruit tip. That interruption is what causes blossom end rot: a sunken, leathery brown patch on the fruit’s blossom end, not a soil calcium deficiency in most cases [1]. Water deeply enough to moisten soil to at least 6 inches, and keep that schedule even through the peak of the 95-day ripening window.
Pimento Problems: Symptom, Cause, Fix
Most pimento problems trace back to one of six causes — inconsistent watering, wet foliage, heat, or one specific virus that a resistant cultivar sidesteps entirely.
| Symptom | Likely Cause | Fix |
|---|---|---|
| Sunken, leathery brown patch on fruit tip | Blossom end rot — inconsistent watering interrupts calcium transport | Water on a fixed schedule; never let soil fully dry between waterings |
| Angular, water-soaked leaf spots that turn brown | Bacterial leaf spot, spread by wet foliage and contaminated tools | Water at the soil line, sanitize pruners, rotate out of peppers 3+ years |
| Sudden wilting of the whole plant, no recovery overnight | Bacterial wilt — soilborne, no cure once established | Remove and discard the plant; do not compost; rotate beds long-term |
| Sunken, dark, spreading spots on ripening fruit | Anthracnose fruit rot, favored by humid, wet conditions | Improve airflow via the 18-24 inch spacing, remove infected fruit promptly |
| Flowers dropping with no fruit set in mid-July heat | Nighttime temperatures above 75°F disrupting pollen viability | Afternoon shade cloth, midday misting; fruit set resumes once nights cool |
| Mottled, distorted young leaves with no pest visible | Tobacco Mosaic Virus, spread by aphids and handling | Grow a TMV-resistant cultivar such as Pimiento Elite; control aphids, wash hands between plants |
The takeaway: if a pimento is wilting or spotting, check watering consistency and foliage moisture first — those two factors drive the majority of pimento problems before disease pressure or pests ever become the cause.
Picking Green vs. Waiting for Red
A pimento left to fully ripen concentrates more sugar and loses the faint bitterness green fruit carries, which is why nearly every pimento cheese and roasting recipe calls for red fruit specifically — unlike a bell pepper, which is commonly picked and eaten green. Picking some fruit green does free up the plant to set a new round of flowers, so a mixed harvest (some green, most left to redden) trades total pod count against peak flavor in individual fruit, the same trade-off that applies across the pepper family.
Cut the stem with snips rather than pulling the fruit — pimento branches are brittle and pulling can snap the whole stem [1][3]. Harvested peppers hold for 2 to 3 weeks in the refrigerator at 45-50°F and 95% relative humidity; a green-mature pimento pulled indoors before frost will continue coloring at room temperature over the following 1 to 2 weeks, though it won’t develop quite the same sugar content as one ripened on the plant.
Why Pimentos Roast and Peel So Cleanly
Wall thickness is what makes a pimento roast well: a thin-walled pepper collapses under direct heat before its skin fully chars, while a pimento’s dense flesh holds its shape through the 8-12 minutes of charring most roasting methods call for. Once the skin blisters and blackens, sealing the pepper in a covered bowl or paper bag traps steam against the loosened skin — that trapped steam is what separates skin from flesh cleanly, and a thicker wall gives the steam more surface to work against without turning the fruit to mush underneath. It’s the same mechanism that makes poblanos a popular roasting pepper, applied to a sweeter, milder fruit.
Skip this step with a thin-walled pepper and you’ll notice the difference immediately: the flesh scorches through before the skin fully blisters, and what steam does form escapes too fast to loosen much of anything. That’s the practical reason recipes calling for roasted red peppers specifically name pimentos, bells, or poblanos rather than “any sweet pepper” — wall thickness isn’t a minor cosmetic detail here, it’s the mechanism the whole technique depends on.

Not every pimento looks like the smooth, heart-shaped fruit on a seed packet — a related group of ribbed, flattened Hungarian-type peppers, often sold as “cheese peppers,” shares the same thick flesh and mild sweetness in a squatter shape built for stuffing whole. If speed matters more than tradition, pick Round of Hungary or Pimiento Elite; if you’re growing specifically for classic pimento cheese or stuffed olives, Truhart Perfection and Pimiento L are the varieties those recipes were built around.
| Variety | Days to Red | Fruit Size | Wall Thickness | Best Use |
|---|---|---|---|---|
| Truhart Perfection | ~94-101 (80 to green + 2-3 wks) | Medium, classic heart shape | Thick | Roasting, pimento cheese |
| Pimiento Elite | ~87-94 (matures ~1 wk earlier than OP types) | 76mm x 63mm, heart-shaped | Thick, TMV-resistant | Roasting, canning |
| Round of Hungary (cheese pepper) | 75 (fastest of the group) | 2-2.5in wide x 3-3.5in tall, flattened globe | Very thick | Whole stuffing |
| Sweet Apple Pimiento | Longer-season (Hungarian import) | Many-lobed, medium-large | Thick | Stuffing, pimento cheese |
| Sheepnose Pimento | Mid-season heirloom | Tomato-shaped, medium | Thick, very meaty | Slicing, pimento cheese |
The single biggest difference in that table isn’t heat or size — it’s shape and speed. Round of Hungary reaches red about three weeks before Truhart Perfection, and its flattened, ribbed form holds a stuffing filling more like a small bell pepper than a classic pimento does [2][4].
Saving Pimento Seed Without Cross-Pollination Surprises
Pimentos are Capsicum annuum, the same species as most hot peppers grown in home gardens, and the two will readily cross-pollinate if planted close together. A pimento seed saved from a plant grown 15 feet from a jalapeño won’t turn hot in that fruit — cross-pollination changes next year’s seed, not this year’s pepper — but growers who save seed for next season do isolate their sweet and hot plantings to keep that seed true. Our hot pepper vs. sweet pepper cross-pollination guide covers the isolation distances and manual-pollination workarounds seed-savers use to keep a pimento line pure from a nearby jalapeño or habanero planting.
The South Didn’t Invent Pimento Cheese
Pimento cheese is widely assumed to be a Southern original, but the documented history says otherwise. The word “pimento” didn’t refer to a pepper at all until the 1880s — before that it meant allspice — and large manufacturers only began canning imported Spanish sweet peppers under that name in the same decade. Pimento cheese itself, a blend of cream cheese and canned pimentos, was developed in the North by Domestic Science-era cookbook writers: the earliest known print recipes appear in a 1899 Boston cooking magazine, a 1908 Good Housekeeping piece, and a 1909 sandwich cookbook, with commercial production starting around 1910 out of the Midwest and reaching Southern grocery shelves that same May [5].
What is true is that Georgia became the country’s pimento-growing and canning center through the 1920s and 1940s, which put fresh, cheap pimentos in Southern hands right as the spread was being marketed nationwide as a modern soda-fountain food — the crop, not the recipe, is the South’s actual claim to pimento cheese [5].
Frequently Asked Questions
How long does it take a pimento pepper to turn red?
About 95 days from transplant, combining 73 to 80 days to reach full-size green fruit with another 2 to 3 weeks for the fruit to finish coloring to red [1][2][3].
Are pimento peppers the same as bell peppers?
No. Pimentos are a distinct group of Capsicum annuum cultivars bred for a heart-shaped fruit, thicker walls, and a smaller seed cavity than a standard bell pepper, and they typically take about two weeks longer to reach full red.
Will pimento peppers cross-pollinate with hot peppers growing nearby?
Yes — pimentos and hot peppers are the same species and cross-pollinate readily via insects. This only affects seed saved for next year, not the fruit you’re picking this season; isolate plantings if you plan to save true-to-type pimento seed.
Can you eat pimento peppers green?
Yes, though most pimento recipes call for fully red fruit because it’s sweeter and less bitter than green. Picking some fruit green while immature can encourage the plant to set additional flowers.
What’s the difference between a pimento and a cheese pepper?
Both are thick-walled, sweet Capsicum annuum types, but a classic pimento like Truhart Perfection is smooth and heart-shaped, while a “cheese pepper” such as Round of Hungary is ribbed and flattened into a squat globe, and matures noticeably faster.
