Thor Pepper
(Capsicum annuum var. annuum)

Our growing and taste results for the Thor pepper are provided below.

For more detailed step by step instructions for growing the Thor pepper, visit our growing pepper page.

Seed Genetics:  Open Pollinated

Seed Collecting:  Seeds will come true if crosses with other varieties are prevented.  Bag an unopened flower with spun bonded row cover material.  Remove bag when fruit starts forming or petals fall.  Mark stem with a string so you can find it later.  Let the fruit fully mature before harvesting.  Air dry seeds prior to storage.

Fruit:  Green to red.  Narrow chili shape.  1/2 inches wide by about 5-7 inches long.  Curled.  Few seeds.  Thin walls.
: Mildly sweet
:  Grilled, fried, roasted, salsa and sauces

Disease Resistance: Poor.  Black spot on stem. Shriveled tip.  Most seeds were bad.
:  Good
:  70 days per the seed company.  Ours took 87 days. 
: Above average
: Sweet
Plant Shape
: umbrella
Plant Size:

  • Height: ~24 inches
  • Width:  ~18 inches

The Thor pepper had poor disease resistance.  These problems occurred only on this one variety in a large patch of otherwise very healthy pepper plants of many varieties.  All of the Thor plants displayed the same problems. 

It produced a lot of peppers on a big bushy plant.  But, these traits are present in other varieties without disease issues.  We will not be planting this again and hopefully it didn't cross with any of our other plants.

Life Cycle:
     Zone 8 or lower:  Grow as annual

     Zone 9 or higher:  Perennial

Starting Seed Indoors:

  • Start 8-13 weeks prior to the date you move plants into garden in your area.
  • Planting depth:  1/2 inch
  • 2-3 seeds per 1x1x2" cell (LengthxWidthxDepth).
  • Transplant into pots at 4-6 weeks.  Pots 6" tall work well.

Planting Bed Specs:

  • Soil Temp:  + 65˚F.
  • Hole depth: 8-10 inches.  As a rule of thumb, make the hole 2+ inches deeper than the height of the root ball.  This allows for 1 inch of loose soil above and below the roots.
  • Spacing:  18" apart.
  • Planting depth:  Bury root ball and up to 1" of stem.
  • Tilling:  Optional but does improve drainage and helps roots grow.

Light Requirements:  Full Sun.  Peppers like heat but a string of days in the 90's will often halt blooming and pepper development.  This stress can take a week or more to recover from delaying and reducing harvest.  Woven shade cloth supported above the plants by poles is used by some growers to moderate sun exposure.

Watering:  Without rain, peppers need watered well 1 - 2x per week depending on how hot it is.  Your soil type will also affect water needs.  Carefully observing the plants and how long your soil remains damp is the best way to learn how to manage your unique conditions.  To prevent fungal disease water late morning or early afternoon so the sun will quickly dry the leaves and stems.  If you must water on cool, cloudy days, wet the soil below the plants, ie. keep the leaves dry.
