Poblano peppers are a some of the most popular pepper plants in Mexico, and for good reason! They're hot, but not too hot‚ÄĒclocking in around 1000-2000 SHU (Scoville Heat Units) thus making them perfect for a wide variety of culinary applications.¬†

Expect fruits in somewhat of a pod shape about 4" long and 3" wide. They're ready to harvest when they transition from their immature purple hue into a deep green. Left alone, the deep green color will eventually transition into a red. Poblano peppers will be their spiciest if left on the vine long enough to turn red. 


Poblano Pepper Plant Care

Provide at least 6 hours of full sun daily. 8+ hours is better. 

Flower development will occur mid to late summer. Some flowers may be pinched to encourage a bushy plant. Flowers will eventually turn into peppers. 

Water regularly after planting or repotting, keeping soil moist but not wet until the plant is established. We suggest attempting to make sure your poblano plant gets about 1" of water every week during periods of growth.

Poblano pepper plants that get lots of sun and not a lot of water typically produce hotter peppers. Stress, such as not a lot of water, causes the production of capsaicin which results in a higher SHU rating. 

This plant is an excellent companion for cucumber!

Plant 36" apart. 

Planting with tomatoes will repel many pests and attract beneficial insects to your tomato plants.

Do not allow prolonged exposure to temperatures below 40¬įF. Will die if exposed to frost. Often stunted by any temperatures below 60¬įF. Does best in temperatures above 65¬įF.

Toxicity and Risks of Poblano Peppers

Poblano Pepper Plants are considered toxic due to the fact that they contain capsaicin. They don't contain nearly as much capsaicin as some other varieties of peppers, so they're not as much of a threat as others. 

Capsaicin is the chemical in pepper plants that give them their spicy flavor. Too much capsaicin may cause such things as stomach upset, vomiting, diarrhea, and (in severe cases) death. 

Capsaicin is also very irritating to, and may damage the eyes and skin. Use caution when handling peppers or touching any part of the plant. Rubber gloves and eye protection may be used as a protectionary measure. 

Additionally, they're members of the nightshade family, and produce toxic alkaloids.

These toxic alkaloids are most present in the unripe fruit, the stem, and the leaves of a pepper plant.

These parts of the plant may cause injury to a person or pet if consumed in high doses.
