Odontonema callistachyum (Purple Firespike) - An upright evergreen shrub native to Mexico and Central America that grows to 6 to 8+ feet tall with lush deep green foliage and terminal spikes of lavender-purple flowers that appear summer through late winter to year round. Plant in shade to full coastal sun where it tolerates most soils. Water occasionally to regularly. This plant is typically evergreen in our coastal California climate but can be cut to the ground by a hard frost, reemerging in spring to rebound and bloom in the summer. From reports it seems root hardy to around 15 F so it can be grown as a tropical perennial that reaches to 4 feet tall in colder locations or as a summer annual anywhere. It is attractive to hummingbirds.  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Odontonema callistachyum.
