Wrong time of year to be looking for a OG. I'd try again in early spring. And you could try looking under the name 'Red Riding Hood' as it has been marketed and sold under that name as well since 2001.

Mail order into CA can be tricky because of your state's very strict agricultural rules. Many sources outside of CA cannot or will not ship there. I'd look locally.........

@gardengal48 (PNW Z8/9) In our zone 9b climate, ornamental grasses seem to hang in for most of the Winter. I see them being sold at local nurseries year round, although you might be right that no one is buying them in Winter.

All the nurseries here stock lots of "Rubrum". Finding the smaller "Eaton Canyon" variant is very tough.

Ornamental grasses come in two types (turf grasses as well but that's another discussion) - cool season grasses and warm season grasses. Pennisetum - fountain grass - is a warm season type. That means it grows vigorously in summer and once it produces flower heads in mid to late summer or early fall, it starts to go dormant and the roots stop elongating.

The established modus operandi all for warm season grasses is that they should be planted, divided or transplanted only at the start of their growing season as the roots will not 'take' or establish in colder weather or when they begin to go dormant. How much of a concern that might be for you is questionable but it IS an issue in my zone 9a winter climate!
