Bean Varieties by Zone: Bush, Pole, and Heat-Tolerant Picks

May 21, 2026

Most bean varieties germinate when soil reaches 60°F; cold-tolerant cultivars like Provider germinate at temperatures as low as 55°F, though yields improve when you wait for confirmed 60°F. On the upper end, most Phaseolus vulgaris varieties abort blossoms when air temperatures hold above 90-95°F for more than a few days. Your zone’s last frost date and typical summer high are the two data points that determine which bean varieties will actually yield.

For complete regional planting calendars covering beans and other warm-season crops, see the zone-matched regional books at GardeningByZone.

This guide groups variety recommendations by zone band: Zones 3–5 for short-season cool climates, Zones 6–7 for the standard planting window, and Zones 8–10 where summer heat requires careful variety selection.

Zones 3–5 Bean Varieties: Short-Season Picks

Zone 3b last frost averages May 25 to June 5; Zone 5b runs closer to May 1-15. That gives Zone 3 roughly 90-120 frost-free days and Zone 5 approximately 155-165. Bush beans mature in 48-60 days vs. 65-75 for most pole types, making them the default choice in Zones 3 and 4. In Zone 5b, a May 10 direct sow into confirmed 65°F soil gives pole beans enough runway if you choose an early-maturing cultivar.

Bush varieties (48-60 days):

• Provider (50 days): One of the most cold-tolerant bush beans; germinates at soil temps as low as 55°F. Zones 3-6.
• Contender (48-50 days): Stringless, germinates in cool soil, widely available as seed. Zones 3-6.
• Blue Lake 274 (58 days): Higher yield per plant than Provider; consistent germination at 60°F. Zones 4-7.

Pole variety for Zone 5:

• Kentucky Wonder (65 days): Classic heirloom pole bean, reaches 6-8 feet on a trellis, sets reliably in Zone 5 when sown into 65°F soil after May 10. 30 pcs Kentucky Wonder Pole Bush Bean Vegetable Seeds for Planting - Non-GMO Heirloom Variety — $7.90 is a reliable seed source for this variety.

Succession-sow bush beans every 2-3 weeks through June 15 in Zone 5 to extend harvest. In Zones 3-4, one sowing after last frost is the practical limit.

Zones 6–7 Bean Varieties: Standard Planting Window

Last frost in Zone 6b averages April 15-30; Zone 7b runs March 15 to April 1. Soil temperatures at those dates typically sit at 55-60°F, so wait 7-10 days after last frost to confirm soil is at 65°F before direct-sowing. Zone 7a gardens can often run two full successions of bush beans before fall frost.

Bush varieties:

• Blue Lake 274 (58 days): Standard variety; plant at confirmed 65°F soil temperature.
• Roma II (53 days): Flat Italian pod, quick to mature, good for back-to-back successions in Zone 7.
• Dragon Tongue (57 days): Yellow wax with purple streaks; handles Zone 6-7 summer temps without significant blossom drop.

Pole varieties:

• Kentucky Wonder (65 days): Strongest performance in Zones 6-7 with stable 70-80°F nights. Sustained 4-6 week harvest window on a 6-8 foot trellis.
• Rattlesnake Pole (73 days): Streaked purple-brown pod with good heat tolerance at the upper end of Zone 7. Plant by May 15 in Zone 6 for a full harvest before fall frost.

For mixed bush-and-pole plantings in this zone band, Epic Gardening Bean Seed Bundle - 2 Non-GMO Varieties, Includes Bush Beans & Pole Beans, Grow Crisp, Fresh Beans for Cooking, Stir-Fries & Snacking, Perfect for Raised Beds or Containers — $5.99 covers both growth habits in a single bundled seed order.

Zones 8–10 Bean Varieties: Managing Summer Heat

Peak summer in Zones 8-10 pushes daytime highs above 95-100°F for weeks. Most Phaseolus vulgaris varieties abort blossoms above 90°F. In Zone 9a, the productive windows are spring (direct sow late February through March, harvest before June heat) and fall (direct sow late August through September, harvest October through November). Zone 10 compresses the spring window further, making fall the more reliable season.

Heat-tolerant bush varieties:

• Burgundy (56 days): Deep purple pod, AAS winner. Sets pods at higher air temperatures than most green-pod varieties. Zones 8-9.
• Cherokee Wax (52 days): Yellow wax bean with reliable pod set into the low 90s°F. Zones 8-10.

Heat-tolerant pole varieties:

• Rattlesnake Pole (73 days): Top performer in Zone 8 fringe heat. Plant before April 1 in Zone 8b for a full spring harvest.
• Mississippi Purple (65 days): Heirloom selected for Southern conditions; sets pods into the mid-90s°F. Zones 8-10.

Yard-long beans:

Yard-long beans (Vigna unguiculata ssp. sesquipedalis) fill the same garden role as standard green beans with substantially higher heat tolerance. They set pods reliably above 95°F and continue producing through summer heat that shuts down common Phaseolus varieties. Direct sow after soil reaches 65°F; days to harvest run 60-70. A strong option for any Zone 8-10 gardener dealing with 90-plus-degree summers.

Soil Temperature Reference

Accurate readings taken 2 inches below the surface are more reliable than air temperature for timing direct sows. Surface temps warm faster than root-zone temps, especially in raised beds.

Stage	Minimum	Optimal	Upper Limit
Germination	60°F	70-85°F	95°F
Pod set (air)	60°F	70-80°F	90°F
