Bold red flowers so bright, they could be spotted from another planet! Five-fingered flowers uphold the ‘Star Trek Spock Salute’ as they climb spires towering above its columnar smoky deep-purple to olive-green foliage. Striking! This Cardinal Flower forms full, well-branched, strong stems with an exceptionally uniform habit. Lobelia Vulcan Red is often seen along woodland paths but will still offer strong performance in perennial beds and border gardens with moist, well-drained soil. Well-suited for use in rain gardens, around ponds and streams and other moist areas. Lobelia speciosa will handle more sun than classic varieties; however, some shade is beneficial when sited in drier locations. Pairs well with Ferns or Heuchera. Spires will live long and prosper from mid-summer into fall. A must-have perennial. Resistance is futile!

Lobelia General Information

Lobelia are perfect for the spot in your garden that just stays too wet for most plants. Spires of colorful hood-like flowers open from bottom to top. Will naturalize along ditches and streams. Butterflies like them too. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Lobelia Plant Care

Prefers fertile, evenly moist soil. Can be divided every 2-3 years in spring. Allow to self sow. Winter over with stems on. Can be pinched back before flowering to produce more compact plants. May benefit from light winter mulch north of zone 6.
