Product Details

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.

    Great germination rate. They grew slowly at first but once the weather warmed up they became very prolific. I kept cutting them all Summer long. Very nice as an ornamental too. They looked great planted with other flowers.

    This guy has been very prolific for me and my container garden. I placed two plants a bit too close together (oopsies), and they shaded out my rosemary--not that I'm complaining. I perhaps wish the leaves were a bit larger, but the taste is great. My partner loves using it in his mom's Vietnamese dishes.

    Grew as it should! I started a row indoors, transplanted the strongest ones to nursery pots and then to a terracotta pot. I don’t usually have success putting a single basil plant in a pot (it ends up growing leggy), but this is a single plant and I was surprised with how full it has gotten. A beautiful plant—even with blemished leaves as we approach the end of the season. Very low maintenance too.

    I plant basil all over my garden not only does it help protect my tomatoes from pests, but it’s marvelous when making sauce.
