Sandberg bluegrass (ssp. secunda)
Poa secunda J. Presl (Poa canbyi [Scribn.] Howell, P. gracillima Vasey, P. incurva Scribn., P. sandbergii Vasey, P. scabrella [Thurb.] Benth. ex Vasey =ssp. secunda; P. ampla Merr., P. juncifolia Scribn., P. nevadensis Vasey – ssp. juncifolia)
Perennial, 10-60 cm tall with erect culms growing from a dense tuft of short basal foliage. The blades are short, soft, flat, folded or involute, with ligule acute and prominent. The sheaths are rounded, glabrous and persistent. The inflorescence is a panicle, 2-10 cm long and narrow, yellowish-green to purple on colour, not densely flowered, with branches that are short and appressed becoming somewhat spreading during the flowering period. Spikelets are two to five flowered, 4-6 mm long, terate and acute. The glumes are unequal, papery; the first glume is one to three nerved and 2-5 mm long, the second glume is three nerved and 3-4 mm long. Lemmas are minutely scabrous and crisp-pubescent near the base. Awns are absent (Hitchcock, 1971). Photo by Toni Corelli.
Nevada bluegrass (ssp. juncifolia)
Dry woods and open forests, grassy slopes, ridge tops and rocky slopes from low to mid-elevations (Hitchcock, 1971).
Wide range from sandy or silt loams to shallow rocky soils (Hitchcock, 1971).
Dry to moist. One of the most drought-resistant of the bluegrasses (Hitchcock, 1971).
Sun to light shade.
Good forage for cattle and fair for other livestock and deer (Hitchcock, 1971).
fruit ripening time
Early summer (Fulbright et al., 1982)
no seeds per kg
1.98 to 2.04 million (Fulbright et al., 1982).
fruit seed dormancy treatment
Plant in fall with no pre-treatment required. Fluctuating temperatures of 12º C (for 16 hours a day) and 17º C (for eight hours) are required for germination. Sow seeds shallowly.
Vegetative propagation is not effective with this species (Fulbright et al., 1982)
