The Purple Jalapeno is a little smaller and a more ornamental version of the typical jalapeno pepper. The purple jalapeno pepper plants are very productive, with the peppers starting off green, then maturing to a dark purple colour, they eventually turn deep red. It is common for the plants to display all three colours simultaneously, making the plant a gorgeous addition to your garden. The plant is not only ornamental, however. The purple jalapeno peppers are perfectly edible and delicious, and also as hot as a typical jalapeno pepper.
