Several heirloom packs highlight container-friendly crops. Common examples include herbs such as cilantro, basil and parsley noted as doing well in 12-inch containers, and some salad mixes are described as suited to patio pots.
Many salad mixes in heirloom packs can be harvested in about 30 days. Other leafy greens included in these packs often list maturity around 40 days, depending on the specific variety.
Many packs are labeled as organic and/or non‑GMO. Product descriptions commonly use phrases such as "100% Organic and non‑GMO" or "Heirloom seeds non GMO organic." Always verify certification details on the product listing.
