Lobelia cardinalis or cardinal flower is a perennial which typically grows in moist locations along streams, sloughs, springs, swamps, and in low wooded areas.  This is a clump-forming perennial which features erect, terminal spikes (racemes) of large, cardinal red flowers on unbranched, alternate-leafed stalks rising typically to a height of 24 to 36 inches (infrequently to  48 inches).

Tubular flowers are 2-lipped, with the three lobes of the lower lip appearing more prominent than the two lobes of the upper lip. Finely-toothed, lance-shaped, dark green leaves (up to 4 inches in length).  The bloom period is July to September.  Flowers are very attractive to butterflies and hummingbirds.

White and rose colored forms are also available.

  1. This plant I have grown as I love the vivid red colour. However I never manage to keep it a second year as the slugs devour the new growth and I won’t use slug pellets. Funnily enough if you put in a strong healthy plant they don’t eat it. You don’t see them that often to buy here though.

  2. I did not know of this kind of Lobelia, Charie.
    I have a lot of the Blue/Purple Lobelia each year and it is so beautiful, but if this attracts hummingbirds, I’m in!!

    Thank you for the information.

  3. I think the toads in the garden and the garter snakes eat the slugs in my garden… Pretty flower

  4. How lovely, and they attract hummingbirds! 🙂
