Keep in mind when planting that Paramount is thought of as hardy, so this plant will survive close to or on freezing temperatures. Paramount requires a loamy and potting mix soil with a ph of 5.6 - 6.0 - it grows best in weakly acidic soil.
Try to aim for a seed spacing of at least
7.8 inches (20.0 cm) and sow at a depth of around
0.25 inches (0.64 cm). Soil temperature should be kept higher than
10°C / 50°F to ensure good germination.
By our calculations, you should look at sowing Paramount about 35 days before your last frost date.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Paramount is a hardy plant.
