Lobelia cardinalis 
Cardinal Flower

A great plant for bees and butterflies!

This gorgeous hardy perennial with its scarlet flowers also has red tinted leaves making it even more noticeable among its species. In the wild, the cardinal flower (Lobelia cardinalis) grows on riverbanks so a relatively moist border will help it to thrive. This is a great plant for attracting bees and butterflies to your garden too! Plant your Lobelia cardinalis (cardinal flower) in a sheltered, sunny spot and water regularly, especially in times of drought. Do mulch with leaf litter over the winter.

Planting and flowering details
  • Planting
  • Abundantly flowering cardinal flower (Lobelia cardinalis) makes a great pond plant - best planted in a pond basket. Line the basket with hessian and use special pond soil to fill it. Plant the cardinal flower in the basket and fill it up with the special soil. Cover with the edges of the hessian, or straw and a layer or gravel. Place in the pond so that the top of the basket comes to just below water level or at a maximum 15 cm deep. Add bricks underneath the basket if it's otherwise too deep. Full sun or part shade. Best time for planting is May-June.
    This plant looks lovely in a border as long as it retains moisture well. A plant like this with lovely red blooms and red tinted leaves will be very conspicuous.
    Mixing Cardinal flower with other plants.
    The very noticeable red tinted leaves of the cardinal flower (Lobelia cardinalis) will contrast wonderfully with the edge of your pond. This pond plant mixes wonderfully with Butomus umbellatus (flowering rush) and the arum lily (Zantedeschia aethiopica). Wild cardinal flower (Lobelia cardinalis) grows along riverbanks and other marshy spots but even in our drier borders this abundant flowerer will thrive if you water it sufficiently!

  • Care
  • The cardinal flower (Lobelia cardinalis) is a strong plant for the riverside/pond edge and will grow anywhere really. Cardinal flowers will certainly flower in full sun. Remove dead flower heads in the autumn. Split a too large clump in May. Just cut the whole cardinal flower root system into smaller pieces and replant (some of) them.
    Keeping Cardinal Flower (Lobelia cardinalis) Over The Winter
    Cardinal Flower (Lobelia cardinalis) dies back in the winter. As long as the roots remain under soil (or water), the plant will survive. Cut hard back in early spring and you will soon see new shoots appear, ready to treat you to some new flowers in the summer.
