Outstanding Qualities

This amazing perennial is unlike any other lobelia you may have grown.

Culture Notes

This deciduous perennial needs full sun to thrive. It prefers a sandy soil, but any well-drained soil will suffice. Avoid heavy clay and winter wet locations. Once the flowers are finished the seed can be allowed to ripen. It can gently reseed if the conditions are right. If no seed is desired the seed heads can be cut off. Cut to the ground once the foliage begins to fade in autumn.
