context_page_description: Chamaenerion fleischeri, formerly Epilobium fleischeri, commonly known as Alpine willowherb, is a herbaceous perennial plant of the family Onagraceae.
context_section_description: The biological life-form of Chamaenerion fleischeri is [[[Glossary of botanical terms|scapose]] [Raunkiær plant life-form#Hemicryptophytes|hemicryptophyte]], as its overwintering buds are situated just below the soil surface and the floral axis is more or less erect with a few leaves. This plant reaches on average 10–40 centimetres (3.9–15.7 in) in height. The stem is erect and the leaves are usually glabrous and toothed. This plant is quite similar to Chamaenerion dodonaei, but that is much taller and has bristly leaves.
  Chamaenerion fleischeri has fragrant flowers with four pointed thin dark purple sepals and four bright pink ovate petals. Flowering occurs from late June to August.
