Plant Profile: Turtlehead

 

Turtlehead (Chelone glabra and Chelone lyonii) are native perennials to the Eastern seaboard of the United States. The common name describes the interesting flower shape, which resembles that of a turtle’s beak.

They are hardy to USDA Zones 3 to 8. Turtlehead prefer moist, rich soils in full sun to part shade. They need minimal care, but appreciate an occasional top-dressing with leaf compost.  You can also pinch them back in the late spring if the growth is too tall and leggy.

The plants spread slowly by rhizomes and eventually form large clumps. You can propagate them by division, cuttings, or seed.

Chelone glabra has white flowers, sometimes with a pink tinge. It blooms from August through October. Chelone glabra is a larval host and/or nectar source for the Baltimore Checkerspot butterfly (Euphydryas phaeton).  Chelone lyonii has pink flowers and is in bloom a bit earlier in the season than Chelone glabra.

A popular cultivar of Chelone lyonii is ‘Hot Lips’, which is a deeper pink flower than the straight species with bronze-green foliage and red stems.

    1. The foliage should start to emerge in March and definitely be well up by mid-April.
