The photo above shows a close-up of the attractive flower of big-pod lily as seen in meadows along Hat Pt. Road near Granny View in the Hells Canyon NRA........June 28, 2007. Note the broad central transverse, green spot which runs much of the length of the petal.

Characteristics:

Big-pod mariposa lily is a beautiful wildflower with a single erect stem arising to 50 cm tall from a deep seated, tunicated bulb.

A single bract-like leaf is found about midway up the stem. The basal leaf is flat, and may be as much as 30 cm long, and 5-25 mm wide. The venation is parallel, and the leaf has a grass-like shape, although tapering to both ends.

The inflorescence is one to five flowered, with the showy flowers being held erect. The three creamy white petals (they could be a light lavendar too) have a noticeable red-puple blotch at mid petal. The individual petals are obovate to rounded in shape. The sepals are green, ovate to lanceolate in shape, with a pointed tip. The sepals are shorter than the petals.

Although it is a beautiful wildflower, the big-pod mariposa lily should not be dug to bring home. The bulb is found deep underground, there is a great danger of damaging it, and mariposa lilies tend not to survive well in gardens. Instead, leave it alone and enjoy the beauty it adds to nature.


Habitat:

Big-pod mariposa lily is wildflower of grasslands and open coniferous forests.


Range:

Big-pod marioposa lily is found from the Blue and Wallowa Mts of northeast Oregon and southeast Washington, eastward across central Idaho to southwestern Montana and western Wyoming.
