Thai basil is a popular herb in Southeast Asian cuisine and is a flavorful garnish served with Vietnamese pho (a savory broth of noodles and meat). It holds its flavor and texture better after cooking than other basil varieties and adds a kick to salads when sliced and eaten fresh. Sweet Thai's dark purple flowers and intoxicating scent make it a beautiful addition to the flower garden. A terrific container variety.

So Pretty

5 out of 5 stars Jul 20, 2018
I am growing Thai Basil for the first time this year. It is a really pretty plant. I am glad I planted extra, because now I can let some of it flower. The bees love it, it smells great, it hasn't had any pest problems and it is growing vigorously. It tastes a little licorice-y. I personally love it, and eat leaves while I'm out gardening.

Stands up to early spring weather changes in 8b

5 out of 5 stars May 1, 2020
I wanted to get an early start on my herbs and transplanted some Thai basil outside in late February. The transplants experienced crazy weather swings with temperatures in the low 40s and then into the 90s by March. The basil has been slow to grow with the low temperatures but made it through the cold nights, hail, heavy rains, and heavy sun. It is planted in a spot that by mid spring gets full sun (6 hrs+) and by mid summer is exposed to direct sun all day. It has experienced some pest pressure with little negative impact to the plant's health. Zone 8b

Not my first choice

I haven't had as much luck with this basil variety as I have with others. It's much slower to grow. Plant is still healthy and seeds had good germination.

Green Curried Socks

5 out of 5 stars Oct 29, 2020
..yes, I am such a fan of Thai green curry I would eat green curried anything, maybe even green curried socks (if provided in a pair. We all know how annoying a single curried sock can be). Green curry makes EVERYTHING better, but there's a note that I noticed missing in my own cooking when I tried to replicate my favorite dish at home - what's missing? It was a great excuse to go back to the restaurant again and, in these viral times, get more carry-out for "scientific research". I discovered the missing ingredient is this - Thai basil. With its notes of clove and anise, it's much different than Italian (sweet) basil -- and unavailable at my local grocery! One packet is enough for successive sowings even for the most rabid Thai cuisine fan, but I have found that this herb dries fairly well, it thrives in a Phoenix sun, even in a limited area, and even the flower buds are delicious in my dishes. I have not yet served or eaten Green Curried Socks, but I don't doubt that Thai basil can only improve such a toe-tally tempting idea :)
