Noteworthy Characteristics

Amsonia ciliata is a clump-forming perennial that is native from North Carolina to Florida west to Missouri, Arkansas and Texas. It is generally found in sandy soils. It typically grows to 2-3’ tall. Terminal clusters of star-like, light blue flowers bloom in mid spring (May) atop generally erect stems clad with narrow, almost needle-like, green leaves. Foliage turns attractive shades of yellow in fall. This plant is commonly called bluestar or fringed bluestar or downy amsonia.

Genus name honors 18th-century Virginian physician Dr. Charles Amson.

Specific epithet means hairy-margined in reference to the fringe of hairs found on new leaves and plant stems (hence the sometimes use of fringed or downy in the common name).

가두리정향풀과 솔정향풀의 구분  (둘 다 잎이 매우 가늘다) 

 

 

Amsonia ciliata 가두리정향풀  

Amsonia ciliata has fairly narrow leaves, around 4 mm wide. It has hairs on new leaves and on the stem which differentiates it from Amsonia hubrechtii. The flower clusters are held higher above the stem than some other Amsonia, making it one of the showiest in the genus. Amsonia ciliata ‘Spring Sky’ is a very showy cultivar with extra large flowers. Hardy to zone 4.
