  • circleLife cycle

    Purple Loosestrife 'Feuerkerze' begins its life cycle as a seed that germinates in early spring in moist soils. Upon germination, the seedling develops a rosette of leaves near the ground level. As it matures during the spring and early summer, it elongates and forms a sturdy stem, alongside which lance-shaped leaves are arranged in pairs or whorls. Throughout summer, it produces striking spikes of rose-pink to purple flowers that are attractive to bees and butterflies. After pollination, typically by insects, the plant sets seed in late summer to early fall, which are dispersed by water, wind, or animals. The plant then enters a period of dormancy during winter, dying back to the ground if subjected to frost, and re-emerges from its root system the following spring to complete the cycle.

    • The most popular method of propagating Purple Loosestrife 'Feuerkerze', formally known as Lythrum salicaria 'Feuerkerze', is through division. This is typically done in early spring or fall when the plant is not in active bloom. To propagate by division, carefully dig up the plant and gently separate the root clump into smaller sections ensuring that each section has a portion of the root system and a few shoots. These divisions can then be replanted into moist soil at the same depth they were originally growing. It is crucial to keep the newly planted divisions well-watered until they are established. This method creates clones of the parent plant and is quite effective for expanding your garden or sharing with fellow garden enthusiasts.
