High Soil Description:
Sandy or rocky soils. Conditions Comments:
Because June grass is a cool-season grass, companion plants should be chosen to mask its late-summer dormancy. On
the Pacific coast there is a rather large, loosely tufted form with a more open seed head.
PropagationDescription: Propagate by seed sown unstratified in fall or statified in spring. Sow 1/4 deep. Seed germinated best when weather is cool. Seedlings are almost invisible when first emerging. 1- to 3-year old plants may be divided in early spring.
Seed Collection: Collect in Sep. and Oct.
Seed Treatment: Dry stratification is beneficial.
Commercially Avail: yes
