Lobelia tupa is a variety of lobelia, also known as Cardinal Flower. Lobelia tupa is sometimes called "Devil's Tobacco." It's a perennial plant, hardy in zones 4 to 8, with tall, upright stalks and deep red flowers that bloom from summer to fall. Hummingbirds are attracted to the red flowers.
Choose a site with part sun. The soil should be moist (but not soggy) and well-drained. Plant container-grown plants in the spring.
Dig a hole to accommodate the plant's root ball. If planting more than one, space them about 18 inches apart.
Put the plant in the hole, backfill with soil, and compact to remove any air pockets. Water generously.
Place a blanket of mulch a few inches deep around the base of the plant to keep in moisture as well as to protect the plant over the winter months.
Plants should be watered regularly, especially during periods of drought or high heat.
