Known by several different names, the Rose Mallow is clearly a part of the Hibiscus family with it’s large, distinct flowers. The blooms are larger than many in the Hibiscus species have a diameter of up to 30 centimeters (12”). They look like they would only survive in tropical climates, but in fact are very hardy and considered a native plant in Southern Ontario.
Sometimes referred to as a swamp rose mallow, which makes you think they like to sit in water – they don’t. During the growing season they are very thirsty plants and you must keep them well watered (deep watering 2-3 times per week in warm weather) but do not like to stand in water, especially during the winter months.
These bushy shrubs provide some of the most spectacular, big, showy flowers from mid summer to late fall and are available in a range of colours including white, red, lavender, pink peach and even bi-colour varieties. Pollinators love these plate sized blooms. The older the plant is, the more flowers you will have on your shrub that can grow to around 4-6 feet in height and wide. Dwarf varieties can be 3 feet tall and wide. Blooms last only one or two days, but this plant can produce up to 20 flowers in a day.
