Forget Me Not Flower: Meaning, Symbolism & Growing Guide
James Oliver Mercer Reed • 2026-05-14 • Reviewed by Sofia Lindberg
We all know someone who keeps a tiny blue flower pressed in a book from a trip years ago. The forget-me-not has been the blossom of memory for centuries, but this delicate bloom is also one of the most resilient self-seeding perennials you can grow in cool damp spots across Ireland and the UK.
Botanical name: Myosotis · Common names: Forget-me-not, scorpion grass · Bloom season: Spring (April to June in the Northern Hemisphere) · USDA hardiness zones: 3 to 8 · Official state flower of Alaska
Spring (April to June in northern temperate zones)
Pollinators
Bees, butterflies
The pattern: these tiny blooms punch well above their size, supporting ecosystems and carrying centuries of human memory.
Why is it called forget-me-not?
The name originates from a German folk tale set along the Danube River. A knight picked blue flowers for his lady, then fell into the river and shouted “Vergiss mein nicht” as he drowned (Farmers’ Almanac (trusted gardening publication)).
The implication: a medieval emblem of memory created the idea that these blue petals hold a promise never to be forgotten.
What this means: The name carries a 600-year-old promise, rooted in a tragic love story that still resonates today.
What does a forget-me-not flower symbolize?
Forget-me-nots symbolize true love, fidelity, and remembrance, conveying the message “Do not forget me.” The Alzheimer’s Society uses forget-me-nots for memory loss awareness (Fairfax Gardening PDF (botanical reference)). Freemasons have adopted the flower as an emblem after WWII (Thursd (floral culture magazine)).
“Forget-me-not is a humble but glorious flower which appears in frothy blue clouds at the front of borders.”

The flower’s power as a proxy for memory is so strong it became the lifelong emblem for millions through Alzheimer’s awareness ribbons.
The catch: the very symbol of remembrance reminds us that memory, like the flower, is fragile yet persistent.
Do forget-me-nots come back every year?
Most forget-me-nots (Myosotis sylvatica) are biennials that reseed reliably, appearing as perennials in gardens (Farmers’ Almanac (trusted gardening publication)). Some species like Myosotis scorpioides (water forget-me-not) are true perennials, according to RHS data.
In mild climates, they bloom from spring into early summer.
The strategy: For a patch that self-seeds freely, you don’t need new plants each year. Just let the flowers drop their seeds and manage density by cutting back after bloom.
Yes — let them drop seeds after blooming and they will return reliably.
The pattern: plant once, enjoy for years, but cut down after bloom to control spread.
Where is the best place to plant forget-me-nots?
They thrive in moist, well-drained soil with partial shade. Ideal for woodland gardens, under taller perennials, or in borders. In pots, use quality potting mix and water regularly (GardenersWorld (UK gardening magazine)).
The risk: Hot, dry sites are their downfall — they need cool and moist conditions or they die quickly.
Several species are native to Ireland. Myosotis arvensis (field forget-me-not) and Myosotis sylvatica (wood forget-me-not) are common wildflowers in hedgerows and meadows. They bloom from March to June (Wildflowers of Ireland (botanical database)). The Irish name is Lus an dhearmadta (plant of forgetting).
“Field forget-me-not has slightly cup-shaped pale blue flowers with a yellow centre, from 3 mm in cymes, from April onward.”
The confusion about month signals that traditions overlap — either interpretation works.
What flower is called the poor man’s rose?
Lisianthus (Eustoma grandiflorum) is commonly called the poor man’s rose because its ruffled petals resemble a rose at a lower cost (Cut flower expert). It is not related to forget-me-not but is often used in bouquets.
“Myosotis species or scorpion grasses in the Northern Hemisphere.”
