A white flowering evergreen perennial, Penstemon ‘Swan Lake’ gets its name from the pure white flowers.
Variously described as a sprawling or spreading plant, it grows well in a humus rich well drained soil.
The flowers appear on tall stems to around 60 cm in height. Foliage is a deep green, lance shaped with some serration.
Admired for its long flowering period, ‘Swan Lake’ is a Penstemon variety that will flower first in spring and then through to late summer.
With a little dead heading, the length and intensity of flowering makes a perfect plant for the cottage garden border.
Landscaping Uses
Use ‘Swan Lake’ to underplant roses and other tall growing shrubs. Grow it in the garden border as a filler, and use it for cut flowers as well.
Plant it in front of evergreen hedging plants as a contrast plant.
