I was able to have it germinate, both directly sown into ground with light compost prepared for the seeds in my sandy Fresno loam, and was able to get it to germinate, again, only once temperatures were cool enough in late Fall, around late September and mid-to-late October, in seeding plugs using a local non-native plant nursery's 'Seed Starter' mix. Both the planted out Agrostis pallens, from plugs, and direct sowed, are weathering Fresno's intense heat waves. I do water them occasionally, as this is their first year, but I intend to let them brown up when I know they are an established meadow in parts of my garden. I have also purchased Oniongrass, Melica imperfecta, in the past, that is thriving, and Allium unifolium bulbs, which I hope to spread. They bloomed beautifully this year, and went to seed.
I have not yet sowed this last purchase of Agrostis pallens this last spring, as I was busy studying for a grad school level course on Plant Health for its final. The same with the Festuca californica. I have weeding of yarrow I've bought from your nursery to do around some Basketgrass, Muhlenbergia rigens, and some weeding of Hooker's Evening Primrose from around the same Deergrasses/Basketgrasses, but after that is done, I will have more time and energy to devote to furthering the grass and wildflowers in my meadow garden meets oak woodland riparian garden meets coastal sage scrub and chaparral garden. A lot to do. Other wildflowers tolerant of part-shade and part-sun conditions have reseeded themselves, and I am looking forward to buying more clovers and lupines to interplant between the sod grass Agrostis pallens, and the bunch grasses like Festuca californica, Muhlenbergia rigens, Stipa pulchra, and bunch-grass-sod grass mix of Festuca rubra, as well as all the Melica imperfecta, and some Elymus triticoides.
My garden is small, in an urban heat corridor, yet I attract a lot of wildlife, especially pollinators, and I have both your nursery , local plant sales, and Laspilitas nursery, to thank.
Keep up the good work of the seeds you're committing to your clients to plant, sow, and grow.
