- Northern Sea Oats, Wild Oats, Spangle Grass
Formerly Uniola latifolia (it is no longer
included in the Uniola species)
is a perfect choice for any garden in sun or shade. By mid-summer
the growth of the bamboo-like foliage slows and blooming begins.
One of the best ornamental grasses for cut flowers, as its seedpods
don't fracture when dried. This is a beautiful woodland grass
that should be in every garden, if only for its decorative panicles.
Excellent both as a specimen and mass-planted. For maximum blooming,
give it plenty of sunlight and moisture however its foliage
will be a darker green in the shade. In climates with a
long growing season it may self-seed. Reported to be salt
tolerant. We would love to hear from anyone who can confirm
