Description of the plant:
Firecracker bearded iris makes large, slightly fragrant flowers which look like a lit-up firecracker shooting golden yellow sparkles through a dusky bronze-red sunset. They open from late May until mid June atop 70-80 cm tall stems. Sword-like leaves are deciduous, pale green. Hybrid varieties of bearded iris thrive in full sun and should be planted in well-drained but moist soil of any pH. Various sources say different things about pH requirements, however, truth is that if the soil is reasonably fertile acidity does not play a significant role. Do not mistake them for water irises which do like wet and boggy conditions, these hybrids might rot it such environment.
The plants spread with their rhizomes but are not invasive. Unwanted new rhizomes can easily be dug out and transplanted somewhere else. The rhizomes like warmth so if your garden beds are mulched reduce its amount above iris’ roots to minium. Occasional fertilizing is welcome to enhance flowering and plant health. Thanks to showy flowers and variability of colours available they will be both a perfect companion plants for others as well as great features in any landscape design. Fully hardy to min. -40°C (USDA zone 3).
