Types of Green Beans
Bush beans, pole beans, and specialty types differ in growth habit, yield timing, and flavor. This US guide covers the top varieties for every garden size.
Key takeaways
- Bush beans produce all pods within a 2-week window; pole beans produce continuously for 8–10 weeks — choose based on whether you want to preserve or eat fresh
- Pole beans yield 2–3 times more beans per square foot than bush beans over a full season, but require a trellis
- Yellow wax beans and purple beans are both snap beans with the same culture as green types — they turn green when cooked
- Filet beans (haricots verts) must be harvested at pencil thickness or they become tough within 24 hours — they require daily checking
- Days to maturity ranges from 49 days (Contender) to 68 days (Blue Lake Pole) — choose variety by your frost-free window length
What are the main types of green beans?
Green beans divide into three main growth habit types — bush, pole, and half-runner — with dozens of color and flavor variations within each type.
Most US garden centers sell green beans by growth habit (bush or pole), but the differences extend beyond how tall the plant grows. Harvest timing, total yield per season, flavor, and intended use all vary by type. Matching the type to your garden space and cooking goals is more important than any specific variety choice.
| Type | Height | Days to maturity | Yield pattern | Best use |
|---|---|---|---|---|
| Bush bean | 18–24 in | 49–58 days | All pods in 2–3 weeks | Canning, freezing, short-season gardens |
| Pole bean | 5–8 ft | 58–68 days | Continuous 8–10 weeks | Fresh eating, succession planting |
| Half-runner | 3–4 ft | 55–62 days | Semi-continuous | Traditional Appalachian gardens |
| Filet (haricot vert) | 18–24 in | 52–56 days | Continuous harvest needed | Fresh eating only |
| Wax bean | 18–24 in or pole | 50–65 days | Same as bush or pole parent | Fresh eating, pickling |
Beyond these, dried bean types (navy, pinto, kidney) are grown the same way but harvested dry rather than as snap beans. This guide focuses on snap beans — the type harvested when pods are young and tender.
Bush green beans
Bush beans grow 18–24 inches tall with no support needed. All pods mature within a 2–3 week window, making them the best choice for canning and freezing.
Bush beans are the top-selling snap bean type by US seed sales volume. Their concentrated harvest is an advantage for preserving — you get a large quantity at once rather than small amounts spread over weeks. The concentrated production is also convenient for gardeners who travel or have unpredictable schedules.
Best US bush bean varieties:
Blue Lake 274: The benchmark variety for home canning. Straight, round pods at 5–6 inches. Consistent sizing makes them easy to pack in jars. Days to maturity: 58. Works in Zones 3–10.
Contender: The most cold-tolerant bush bean available. Germinates in soil as cool as 50°F, which allows earlier planting than other varieties. Pods are 6–7 inches, slightly curved. Days to maturity: 49. Best for Zones 3–7 with short growing seasons.
Provider: Similar to Contender in cold tolerance. Slightly higher yield in hot weather. A reliable standard in the Southeast. Days to maturity: 50.
Jade: Slightly longer pods than Blue Lake. Holds its tender texture after harvest longer than most bush varieties — an advantage if you’re not processing immediately. Days to maturity: 55.
Mascotte: Compact and container-friendly. Pods held upright above the foliage, making harvest easier. Good for raised beds and containers in all zones. Days to maturity: 55.
The main limitation of bush beans is that one planting yields for only 2–3 weeks. To extend the fresh-eating season, plant every 2–3 weeks from your last frost date until 8 weeks before first fall frost. Three succession plantings of bush beans can produce fresh beans from June through September in Zone 6.

Pole green beans
Pole beans climb 5–8 feet and produce pods continuously for 8–10 weeks from a single planting. They yield 2–3 times more beans per square foot than bush beans over the season.
Pole beans require a trellis, stake, or other vertical support — strings, hog panels, or teepees of bamboo stakes all work. Once established, they climb by wrapping their tendrils around any available support. Installation takes 30 minutes and the trellis lasts for years.
Best US pole bean varieties:
Kentucky Wonder (Old Homestead): A US heirloom grown continuously since the 1860s. Produces flat, broad 7–9 inch pods with excellent flavor. Days to maturity: 65. Hardy in Zones 3–10.
Blue Lake Pole: The pole counterpart to the canning standard. Round, straight pods at 5–7 inches. More disease-resistant than the bush type. Days to maturity: 60.
Rattlesnake Bean: A traditional Southeast US heirloom with purple-streaked pods and mottled seeds. Extremely heat-tolerant — one of the best performers in Zones 7–9 summer heat. Pods turn green when cooked. Days to maturity: 73.
Emerite (Filet Pole): A French filet-type pole bean producing slender pods at only 5–6 inches. Must be harvested at pencil-width every 1–2 days. Flavor is finer and more delicate than standard types. Days to maturity: 60.
Louisiana Purple Pod: A Southern heirloom producing burgundy pods that distinguish harvested beans from plant foliage — an advantage for thorough harvest in dense plants. Turns green when cooked. Days to maturity: 65.
The trade-off with pole beans: the trellis installation investment and the 5–8 extra days to first harvest. But a single planting that feeds fresh beans for 8–10 weeks eliminates the need for succession planting that bush beans require.

Filet beans (haricots verts)
Filet beans are thin, elegant snap beans harvested daily at pencil-width (under 5mm diameter). They become tough and stringy within 24 hours of reaching full size — daily picking is not optional.
Filet beans are the standard at US farmers markets because they look striking and have a more refined flavor than standard snap beans. They are grown exactly like bush or pole snap beans — the difference is harvest management.
Best US filet varieties:
Maxibel: A bush filet bean, 7 inches long at harvest size. The top-selling filet variety in US seed catalogs. Produces evenly sized pods. Days to maturity: 53.
Nickel: The thinnest filet available — pods should be harvested at 4mm diameter. Intensely flavored. Days to maturity: 52.
Emerite (pole): As noted above — a pole filet bean with the same slender profile. The pole habit means a longer production window than Maxibel, which is an advantage when you want daily small harvests over a long period.
Management reality: A 10-foot row of filet beans needs 15–20 minutes of daily harvest attention at peak production. This is the type’s biggest drawback for busy gardeners. If you miss a day, most pods will be too large and tough to eat as filets — they can still be used as regular snap beans or shell beans at that point.
Wax beans and purple beans
Yellow wax beans and purple snap beans are nutritionally and culinarily identical to green snap beans. The color variation makes harvested pods easier to see among dark green foliage.
Yellow wax beans: The yellow color is caused by an absence of chlorophyll. Flavor is mild and slightly buttery compared to green types. Dragon Tongue is the most popular variety — a Dutch heirloom with yellow pods striped in purple, harvested at 5–7 inches. Days to maturity: 57. Bush habit.
Roc d’Or: A yellow bush bean with straighter, more uniform pods than Dragon Tongue. The standard yellow wax type for US home canning. Days to maturity: 55.
Purple Queen: A purple bush bean with 5–6 inch pods. The dark color makes harvesting easy — pods stand out clearly against green foliage. Turns green when blanched or cooked. Days to maturity: 54.
Bountiful: An heirloom yellow wax bean from 1898. Flat pods with a stringless texture. Good heat tolerance for Southern gardeners. Days to maturity: 50.
Half-runner beans
Half-runner beans are a regional type common in Appalachia and the Upper South. They grow 3–4 feet tall — between bush and full pole types — and require minimal support.
Half-runners occupy the middle ground between bush and pole. They produce pods over a longer window than bush beans but do not require the 6–8 foot trellis that full pole types need. A simple wire cage or bamboo stakes at 4 feet is adequate.
Common US half-runner varieties:
White Half-Runner: The traditional Appalachian canning and drying bean. Widely grown in West Virginia, North Carolina, and Kentucky. Pods stringless when young, string present at full maturity. Shell beans at dry stage are used in soups and stews.
Mountaineer White Half-Runner: A slightly improved selection of the classic. More uniform pod size. Days to maturity: 60.
Half-runners are difficult to find at mainstream US garden centers. Seed Savers Exchange and Southern Exposure Seed Exchange both stock multiple half-runner selections.
Choosing by days to maturity
Days to maturity is the most important selection criterion after growth habit. Match the variety’s days to your frost-free window length.
| Days to maturity | Varieties | Best zones |
|---|---|---|
| 49–52 days | Contender, Provider, Maxibel | 3–5 (short seasons) |
| 53–57 days | Jade, Dragon Tongue, Mascotte | 4–7 |
| 58–62 days | Blue Lake 274, Blue Lake Pole | 5–9 |
| 63–68 days | Kentucky Wonder, Rattlesnake | 5–10 |
| Over 68 days | Heirloom runners, traditional types | 7–10 |
In Zone 5, the frost-free window is about 120–140 days. You can fit three plantings of a 49-day bush bean (3 × 49 = 147 days) if you start at the last frost date — though spacing the plantings 3 weeks apart keeps production staggered rather than stacked.
In Zone 8–9, heat tolerance matters more than days to maturity. Rattlesnake Pole and similar heat-adapted varieties outperform Northern standards like Blue Lake in July–August temperatures.

Growing green beans from seed
Plant green bean seeds 1–2 inches deep, 3 inches apart in rows 18–24 inches apart. Soil must be above 50°F — cold soil causes seed rot more often than frost damage.
Green beans do not transplant well — the taproot is sensitive to disturbance. Always direct sow. Germination takes 7–14 days at 60–70°F soil temperature. At 50°F, germination takes 3 weeks and the germination rate drops from 90% to 60–70%.
Soil: Well-drained, slightly acidic soil at pH 6.0–6.8. Green beans fix their own nitrogen through root bacteria — avoid heavy nitrogen fertilizer at planting, which stimulates leaf growth and reduces pod set.
Support: Install pole bean support before planting or immediately after, before vines begin reaching for support. Moving a trellis after vines start climbing disrupts and breaks the delicate tendrils.
Watering: Consistent moisture during flowering and pod development is critical. Dry soil at flowering causes blossom drop and reduced yields. Wet soil during seed germination causes rot — the soil must drain well.
Harvest: Pick pods when they feel firm and snap cleanly. The seeds inside should be just beginning to form — you should feel small bumps but no hard seeds. Overmature pods reduce the plant’s signal to produce new flowers. Harvest every 2–3 days during peak production.
