Top Ten Florida Green Roof Plants, Salvia lyrata, Lyreleaf Sage

You can not find a better green roof plant than Lyreleaf Sage, Salvia lyrata.  I love to see this very special native wildflower growing across rooftops.

Her evergreen foliage offers an exquisite blend of deep greens, purples and burgundy with leaves laying flat against the ground and flower stems extending vertically to about 18 inches (45 cm).  Note the lyre shaped leaf form.

Flowers generally are a deep ocean blue but I have seen the occasional white colored flower populations.

Lyreleaf sage's ability to thoroughly cover open soil media keeps weeds at bay throughout the year.  A mature population of Salvia lyrata can provide a dense, luxurious appearance.

Lyreleaf sage transplants easily.  If you can not find the plant in a nursery then it is usually readily found in backyards and alongside the roadside in front of most vacant lots here in the southeast.  Just make sure that when transplanting you are not transferring root-knot nematodes from the ground up to your roof project (though the pests usually can not survive the temperatures on a roof).

This special plant will provide you with many surprises.  She will be green most of the winter when other plants have that sleepy brown appearance and provides masses of bee and other pollinator attracting blooms when most other flowers are still just thinking about blossoming.

Check out our previous posts about this special plant.  Read the Seeds for Green Roof Post about her also!  Planting this extremely hardy and drought tolerant species will pay off in big green roof successes.
