Lobularia Germination Information

Lobularia Seed Germination How to Sow Lobularia:

  • Best sown indoors 4-6 weeks before last frost at a temperature of 65 to 70°
  • Provide NO cover as light aids in germination
  • Expect germination in 8-15 days
  • If sown outdoors, do so in early spring directly where the plants are to grow
  • If sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Lobularia:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Space 5-8 inches apart in full sun and average, well-drained garden soil

Soil: Sweet Alyssum can also be grown in gravel walkways, edges of gravel drives, or to fill paving cracks where it likes it moist

Temperature: Plant is tolerant of drought and heat. In the deep South, Sweet Alyssum is grown outdoors in the winter as it prefers 55-60° days and 50-55° nights

Additional Care:  Indoors, be sure to provide full sun, good air circulation, cool nights (50-55°), and to keep the soil evenly moist. Shear plants occasionally to encourage repeat flower production

Appearance and Use:

Many uses from borders, edgings, container plantings, rock gardens, and as a house and conservatory plant. Plants are vigorous, small mounds from 3-6 inches high by 6-12 inches wide. Flowers are tiny, cross-shaped and slightly cupped in a range of colors from lavender, pink, rose, purple, and white. They are sweet smelling and produced in copious quantities from June to frost. The gray-green foliage is lance-shaped
