Amethyst Basil is a dark purple variation of Genevese Basil.

Nearly black in color. 

Provides a wonderful smell to the areas that it grows in. 

It can be grown indoors and on your patio as a potted plant, and also thrives when planted outside assuming the soil and air temperatures are above 50°F.

Grows beautiful white flowers that attract pollinators and may be used in cooking. Pinch flowers or top plant (remove flowers by cutting above a node) to prevent plant from going to seed. 


Amethyst Basil Care

Provide at least 6 hours of full sun daily. 

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

Established basil does best with the minimal amount of water and fertilizer required to keep it alive. Over watered and over fertilized basil seems to not have a taste as delicious as it should.

Flower development will occur mid to late summer. Flowers may be pinched to encourage a bushy plant full of foliage. Flowers may also be left alone to provide area beautification, attract pollinators, harvested for use in cooking, or allowed to go into seed.

By pinching and preventing blooming you also help preserve the plants natural volatile oils which are responsible for the plants robust flavor and aroma.

Basil is a great companion plant to most vegetables, but avoid growing with cucumbers and other herbs (especially sage). 

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

Do not allow exposure to temperatures below 50°F. Will die if exposed to frost.

Additional Information

Botanical Name of Amethyst Basil

  • Ocimum basilicum 'Amethyst'

Toxicity and Risks of Basil

Ocimum basilicum is not considered to be toxic to people or pets when consumed in normal doses; however, it does contain chemicals such as estragole that can be toxic in large doses. 

It is very unlikely that anyone would consume enough basil to be concerned about the threat of estragole poisoning. One must be careful; however, not to drink too much basil tea or basil oil, as these sources often concentrate chemicals. As such, we suggest drinking no more than 2 cups of basil tea a day, and not eating or drinking any basil oil without guidance from a medical professional.
