Pure Live Seed

Seed is provided in Pure Live Seed (PLS) unless otherwise stated.

Pure Live Seed (PLS) expresses the viable seed content of a seed lot using its purity and germination or viability test results. It helps you compare seed lots and calculate how much bulk seed is needed to meet a specified PLS planting rate.

PLS weight and bag weight

PLS weight is not the same as the total weight of seed in a bag. For example, a lot with 80% purity and 75% viability contains 60% PLS: 80 × 75 ÷ 100 = 60. Supplying 10 lb PLS from that lot requires about 16.67 lb of bulk seed.

Use the current seed test and the stated basis of the mix specification. Germination calculations may include applicable hard or dormant seed. Seed-count estimates also require the number of seeds per pound; PLS alone does not provide a seed count.

What to check when buying a mix

Check whether each rate is stated in PLS pounds, bulk pounds, or a combination. A mix with both bases should not be described as having an all-PLS total.

PLS does not remove weed seeds or guarantee establishment. Review the seed label and analysis for weed content, and match site preparation, planting conditions and follow-up management to your project.

Purple love grass grows most actively in summer heat and flowers toward the season's end. Its low clumps suit dry, sandy or gravelly ground in full sun.

For Eragrostis spectabilis, choose full sun and dry soil. Recorded habitats include sand barrens; Dry sand prairies; Oak openings; Dry sandy shores. Reported height: 1-2 ft.

Growth habit: basal tufts with upright to widely spreading stems. Allow space for this growth between neighboring plants over several seasons, rather than spacing only for the size of a young plant.

Plant characteristics

A short clumping warm season grass, Purple Love Grass can be a charming border plant. It prefers prairie and savanna situations with dry, sandy or gravel soils. Airy purple seed heads appear in late August, giving it a cloudlike appearance. As seeds mature, the flower stems loosen and detach, like tumbleweed. Eragrostis comes from the Greek eros (love) and agrostis (grass).

  • Flower Color green/purple
  • Flower Time July, August
