Description

Sisyrinchium mucronatum

Also known as:

needletip blue-eyed grass

,

Scientific Synonyms:

Sisyrinchium intermedium

Description

Sisyrinchium mucronatum is a small, slender member of the Iris family, with thin, grass-like basal foliage. It forms open clumps, with flowering stems that reach 16" at most. The terminal flowers are varying shades of blue to purple, 3/4 across, with petals tipped with a conspicuous needle-like point, hence the common name. Although each stem will bare several flowers, only one will open at a time.

Cultivation

Needletip blue-eyed grass is a well-behaved species. Typically found in open fields, meadows, and also bog-like settings, it is well-adapted to areas that are moist to wet, and will also tolerate dry spells once established. It is intolerant of shade and should be planted in a sunny location. Due to its small size and fine texture, it is best planted in groups in the front of a border. The blooming period lasts about a month in early to mid-summer. Zones 3-8

Propagation

Easily propagated by clump division and root cuttings, in early spring or fall. Can be propagated by seed, but these lack vigor and seedlings are slow to reach flowering maturity.

Additional Notes

This species is similar to Sisyrinchium angustifolium, but is smaller and more slender, and is also more tolerant of wet conditions. The common name is somewhat of a misnomer; though its foliage is grass-like, this is not a grass, but rather a member of the Iris family.
