How to Grow:

Basil likes warm temperatures. Germination, whether in potting mix or garden soil, must occur between 65-70F. Germination within 1 week is typical.

If growing to transplant in a potting mix, it will take 5-7 weeks to make a transplantable young plant. Growing should occur at 70-75F and in medium to bright light.

If sowing directly into the garden, sow when the soil is warm, about the time you would typically transplant tomatoes or sow summer squash seed. Visible germination of the basil seed will take 10-14 days. Plants can begin to be harvested in another 4-5 weeks. Side shoots will appear from leaf nodes on any remaining plant stem, and the side shoots become harvestable within 4-5 weeks.

Piedmont is a vigorous grower, on a densely-branched plant, with a strong production of side shoots. Piedmont’s foliage remains healthy under typical garden conditions. It is strongly tolerant to basil downy mildew (BDM), but Piedmont may not be 100% resistant to all strains of BDM, in every year, in every geographic region, or under every condition.

Judges Observations
  • “Very disease resistant; Stayed vegetative weeks longer than comparison varieties (very delayed flowering)”
  • “Shows excellent DM resistance, even better in late September.”
  • “It is bushy, it has a good flavor, and it has a good DMR package.”
  • “We had fantastic basil trials this year! This trial variety had extremely dense foliage. We planted 25 plants of each variety, and boy, was that a mistake! We were harvesting with hedge trimmers and garbage bags. There is such a thing as too much basil!”
  • “Strong aroma and taste. Healthy plants throughout the entire growth cycle.”
  • “A strong basil flavor on entry. Much better than comparison. More refined of a plant. Internodes are shorter. Keeps well.”
