Fireweed Chamaenerion angustifolium 'Stahl Rose'
ABOUT
Chamaenerion angustifolium 'Stahl Rose,' commonly known as fireweed, is a perennial herbaceous plant renowned for its showy flowers and resilient growth. Its stem is upright and adorned with spirally arranged leaves that are narrow and elongated, often lance-shaped with a slightly serrated edge, presenting a vivid green hue. The most striking feature of fireweed is its majestic inflorescence that graces the top of the plant. The bloom comprises numerous small flowers closely packed in a tall, columnar cluster. Each flower possesses a delicate shade of pink to rose that forms a soft gradient along the inflorescence. The petals are slightly notched, giving them a unique and recognizable silhouette against the greenery. Amidst the petals, you will find a group of stamens with conspicuous anthers that lend a subtle contrast to the softer hues of the petals. The visual appeal of fireweed is further enhanced by its seed pods, which, upon maturity, split open to release white, fluffy seeds that can be carried away by the wind. Fireweed is often found adding a touch of color to the landscape, dazzling onlookers with its floral display that not only adds aesthetic appeal but also supports various pollinators. This variety, with its 'Stahl Rose' epithet, suggests a particular resilience or perhaps a unique shade akin to steel or metal, hinting at a robust nature and a distinct coloration within the range of pink tones typically observed in fireweed blossoms. Overall, fireweed’s appearance is both enchanting and robust, contributing to its popularity in natural and cultivated settings.

WaterThe Fireweed (Chamaenerion angustifolium 'Stahl Rose') should be watered deeply once a week, providing about 1 to 1.5 gallons of water per plant each time, depending on soil conditions and climate. During hot or dry periods, watering frequency may increase to maintain moist soil. It's important not to overwater or let the plant sit in soggy soil. A slow and steady watering method, such as drip irrigation or a soaker hose, is preferable to ensure that water reaches the roots without oversaturating the soil.
LightFireweed prefers full sun to partial shade and thrives in a location where it can receive at least six hours of direct sunlight a day. This plant is adaptable but will produce the best flowering results in a spot with plenty of sunlight, though some afternoon shade can be beneficial in areas with very intense sun.
TemperatureFireweed can tolerate a wide range of temperatures, surviving in conditions as low as -40°F and thriving in areas where summer temperatures reach up to 90°F. The optimal growing temperature for this plant is between 60°F and 75°F, where it can achieve vigorous growth and abundant flowering.
PruningFireweed benefits from pruning to remove spent flowers and encourage additional blooming. Deadheading, or cutting off the faded flowers, can be done as soon as they begin to wilt, usually in late summer or early fall. Cut the flowering stems back to the base of the plant after flowering to maintain a tidy appearance and promote healthy growth for the next season.
CleaningAs needed
SoilFireweed, known botanically as Chamaenerion angustifolium 'Stahl Rose', thrives best in a well-draining soil mix with a slightly acidic to neutral pH of 5.5 to 7. A blend of loamy soil, peat, and perlite or sand can provide the ideal texture and fertility for healthy growth. Adding organic matter like compost enhances nutrient content.
RepottingFireweed, or Chamaenerion angustifolium 'Stahl Rose', generally does not require frequent repotting and can be repotted every two to three years. It's best performed in the spring before new growth starts, providing the plant with fresh soil and additional room for root development if it has outgrown its current pot.
Humidity & MistingFireweed, whose scientific name is Chamaenerion angustifolium 'Stahl Rose', prefers moderate humidity levels. While it is tolerant of various humidity conditions, aiming for an environment with around 40% to 60% humidity is ideal for this species.
Suitable locationsIndoor
Provide bright light; water when top soil feels dry.
Outdoor

Life cycleChamaenerion angustifolium 'Stahl Rose', commonly known as fireweed, begins its life cycle as a seed released from the mature plant's distinctive elongated seed pods. Once the seed germinates in suitable conditions, typically in open and disturbed areas, a rosette of leaves forms near the ground as the plant enters its vegetative stage. As it matures, the stem elongates, and fireweed develops tall floral spikes with pink to rose-purple flowers that bloom from the bottom upwards during the reproductive stage in mid to late summer. After pollination by insects such as bees and butterflies, the flowers develop into slender pods filled with numerous tiny seeds that have tufts of hair, aiding in their wind dispersal. The plant can also spread vegetatively through aggressive underground rhizomes, expanding its presence in an area. Fireweed is a perennial, and after the flowering stage, it will enter a period of dormancy during winter before reemerging in the spring to repeat its life cycle.
PropogationPropogation time
Late winter-early spring
Propogation: The Chamaenerion angustifolium 'Stahl Rose', commonly known as fireweed, is typically propagated through seed sowing. Seed propagation is most successful when carried out in late winter or early spring, taking advantage of the natural stratification period provided by winter. To propagate fireweed by seed, one should first collect the mature seed capsules from established plants as they begin to open. Seeds can then be scattered directly onto a prepared soil surface where they will require light to germinate. Ensure the soil is kept moist but not waterlogged. The seeds are quite fine, and it is not necessary to cover them with soil, allowing light to trigger the germination process. Seedlings will appear in a few weeks and can be transplanted to their final positions once they have developed a strong root system and are large enough to handle.
