Get the most for your time when buying wheatgrass seeds by knowing your varieties and checking for quality before and after you buy. Wheatgrass (Triticum aestivum) is an annual, but it also does well indoors and requires little maintenance. You can buy wheatgrass in bulk or by the packet, but it's best to buy only what you'll use in a short time so it stays fresh.
Choosing Wheatgrass Varieties
Of the more than 500 types of wheat (Triticum spp.), you only need to know a handful of varieties when purchasing seed for sprouting, including "Hard Red" (Triticum aestivum "Hard Red"), "Liquid Sunshine" (Triticum aestivum "Liquid Sunshine") and "Kamut Ultimate" (Triticum aestivum "Kamut Ultimate"). "Hard Red" is one you're likely to find online because it has a high germination rate and you can grind it into a medium-gluten all-purpose flour, too. "Liquid Sunshine" is a favorite among heirloom lovers as is "Kamut Ultimate," an versatile seed known as an early sprouter.
Understanding Wheatgrass Quality
Check seed quality before and after you buy. When buying online, look for the seed's germination rate, microbial testing and its USDA certification. A quality wheatgrass seed has a 98 to 100 percent germination rate, undergone microbial testing and has a USDA organic certification, if you're buying organic.
When you've opened the seeds, pass them through a sieve, and onto a flat white surface and inspect for any damage, such as cracking, splitting or discoloration on the seed coat. If you purchase in five- or 10-seed packets, each seed should be perfect. If you buy in bulk, expect a 5 percent damage rate.
