How to Grow Lobelia Tupa


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.

Step 1

Choose a site with part sun. The soil should be moist (but not soggy) and well-drained. Plant container-grown plants in the spring.

Step 2

Dig a hole to accommodate the plant's root ball. If planting more than one, space them about 18 inches apart.

Step 3

Put the plant in the hole, backfill with soil, and compact to remove any air pockets. Water generously.

Step 4

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.

Step 5

Plants should be watered regularly, especially during periods of drought or high heat.
