Sisyrinchium striatum (also called pale yellow-eyed grass)
Might be 'Aunt May'
Evergreen clump-forming perennial with upright sword-like leaves and spires of small pale yellow cup shaped flowers. An excellent foil for purple and blue.
Flowers in early to mid-summer.
Habit - upright, though the flowering stems sometimes lean. H&S: 50cm-90cm
Stems - upright, grey-green.
Leaves - upright fan of straight sword-like, grey-green leaves.
Flowers - tall stems hold clusters of small, pale yellow flowers. Look more closely and you'll see the fine purple stripes that give the plant its species name (striatum = striped). The centre of the cup-shaped flower is speckled with the same purple.
Well drained, neutral to slightly alkaline. Dislikes winter wet.
Remove spent flower heads if you don't want it to set seed, which it will do freely. Remove old leaves as they become tatty. Dig up and divide large clumps every couple of years.
Will set seed and spread naturally, or divide clumps in spring.
