Few flowers are as quietly beloved as the forget me not those hazy drifts of sky-blue blooms with cheerful yellow eyes that carpet spring gardens. The best part? Learning how to care for forget me nots is genuinely easy, because these little plants mostly look after themselves. Give them a bit of shade, moist soil, and room to self-seed, and they’ll return year after year. This guide covers everything: care, planting from seed, growing conditions, what to expect through the seasons, and the tender meaning behind the flower.
What Are Forget Me Nots?
Forget me nots are the flowering plants of the genus Myosotis, part of the borage family (Boraginaceae). As the Royal Horticultural Society notes, the genus can be annual, biennial, or perennial, producing clusters of small, salver-shaped blue flowers — each with a distinctive yellow or white eye — in spring and early summer. Pink and white forms exist too.
The most common garden type is Myosotis sylvatica, the woodland or garden forget me not, a low grower reaching just 5–12 inches tall. Its cousin Myosotis scorpioides, the water forget me not, thrives at pond margins and in boggy ground. And the Alpine forget-me-not (Myosotis alpestris) holds a special honor: it’s the state flower of Alaska.

Do Forget Me Nots Come Back Every Year?
Yes — forget me nots do come back every year, but not in the way most people expect. According to the North Carolina State Extension, the garden forget me not is technically a short-lived perennial that’s usually grown as a biennial or annual. Individual plants are fleeting — they often die back by mid-summer after flowering.
So why do they seem to return faithfully? Because they self-seed prolifically. Each spring’s flowers drop seed that germinates and blooms the following year, creating the illusion of a permanent planting. In practice, once you have forget me nots, you’ll likely have them for years — they persist in the garden by reseeding themselves, not by individual plants living a long time.
Do Forget Me Nots Spread?
Yes — forget me nots spread readily, and this is the same mechanism that brings them back: self-seeding. They scatter seed freely and, in ideal conditions, sometimes aggressively, naturalizing into charming drifts under trees and among spring bulbs. For most gardeners this is a delight, not a nuisance.
If you’d rather keep them contained, control is simple: deadhead the spent flowers before they set seed, and pull unwanted seedlings — they lift out easily by hand in fall or spring. This lets you enjoy the flowers while deciding exactly where the next generation appears.
Pro tip: forget me nots pair beautifully with tulips and daffodils. Let them fill the gaps around your spring bulbs — the blue haze makes the bulbs’ colors pop, and both peak at the same time.
Light & Where to Plant
Forget me nots prefer partial shade, echoing their woodland origins. They’re happiest with morning sun and protection from harsh afternoon rays, or in light, dappled shade beneath trees and shrubs. In cooler climates they’ll take full sun quite happily — just remember the more sun they get, the more water they’ll need.
Do Forget-Me-Nots Grow in Shade?
Yes — forget me nots grow well in shade, and it’s one of their greatest strengths. They tolerate partial and even fairly heavy shade, making them one of the best choices for brightening up dim, moist corners where many flowers struggle. Dappled shade beneath deciduous trees is close to their natural habitat.
Soil, Water & Feeding
Forget me nots need moist, well-drained soil that’s rich in organic matter, ideally with a slightly acidic to neutral pH around 6.0–7.0 — the kind of humus-rich ground you’d find on a woodland floor. Consistent moisture is the key to healthy plants and long-lasting blooms, so water during dry spells and consider mulching to retain moisture.
Feeding is barely necessary. These are undemanding plants that seldom need fertilizing in decent garden soil; overfeeding simply produces floppy growth. If your soil is poor, a little compost worked in at planting is plenty.
How to Plant Forget Me Nots from Seed
Planting forget me nots from seed is the easiest and cheapest way to establish them. Here’s the reliable method:
- Choose your timing. Sow directly outdoors in spring, or — for the traditional approach — in mid-summer (May–June in the UK) so plants establish and bloom the following spring.
- Prepare the bed. Loosen the top few inches of moist, weed-free soil and rake it level.
- Sow shallowly. Scatter the seeds and cover them very lightly — no more than about ⅛ inch of soil. Press gently for good seed-to-soil contact.
- Keep moist. Mist or water gently and keep the soil consistently damp. In warm soil, seeds germinate in just a few days.
- Thin the seedlings. Space or thin plants to about 8–12 inches apart. Good airflow here is important — overcrowding invites powdery mildew.
Planting in Pots & Containers
Forget me nots grow well in containers, where their tumbling blue flowers look lovely spilling over the edge of a pot or window box. Use a good peat-free, moisture-retentive potting mix, ensure the container has drainage holes, and water more often than you would in the ground — pots dry out fast. They’re perfect partners for potted tulips.
Starting Seeds Indoors
You can start forget me nots indoors to get a head start on the season, sowing 8–10 weeks before your last frost and transplanting out once the danger of frost passes. A bright windowsill or a grow light works well for sturdy seedlings — see our guide to the best grow lights for indoor plants. One honest caveat: forget me nots are cool-season garden plants, not permanent houseplants. Start them inside, but plan to move them outdoors — they won’t thrive long-term as an indoor plant.
Growing Stages & What to Expect
A forget me not’s life follows a predictable rhythm. From seed, it germinates within days in warm, moist soil, then forms a low rosette of fuzzy, gray-green leaves. Through cool weather it bulks up, and in spring it erupts into that signature cloud of blue. After flowering, the plant sets abundant seed and typically begins to die back by mid-summer — this is normal, not a failure. By then, the next generation of seedlings is already waiting in the wings to repeat the cycle.
Growing Zones & Climate
Forget me nots thrive in cool, temperate climates, roughly USDA Zones 3–8. They love the mild, moist conditions of spring and dislike prolonged heat.
This is why hot-climate gardeners — for example in Florida and the Deep South — struggle with them. In high heat and humidity, forget me nots tend to fizzle out quickly. If you garden in a warm zone, treat them as a cool-season annual: sow in fall or winter for late-winter and early-spring color before the heat arrives, rather than expecting them to persist through summer.
Common Problems
- Yellow leaves: usually overwatering or poor drainage — let the soil drain and ease off. But remember, yellowing and dieback after flowering (by mid-summer) is completely natural for these short-lived plants.
- White powdery coating on leaves: powdery or downy mildew, common after flowering and worsened by overcrowding. Improve airflow, avoid wetting the foliage, and remove affected plants.
- Leggy, sparse growth: too much shade or overcrowding — thin plants and give them a little more light.
- Spreading too much: deadhead before seeds set and pull surplus seedlings.
The good news: forget me nots have no serious insect pests and are both deer- and rabbit-resistant, so most trouble is easily managed. For more on diagnosing plant issues, visit The Infirmary.
Forget Me Not Meaning & Symbolism
Beyond the garden, the forget me not carries one of the most poignant meanings of any flower: true love, remembrance, and faithfulness. The name itself is a plea not to be forgotten, and it has symbolized enduring devotion since the Middle Ages, when lovers exchanged the blooms as a token of fidelity.
The most famous legend, recounted by the Fairfax Master Gardeners, tells of a medieval knight walking beside the Danube with his beloved. Gathering flowers for her, he slipped and was swept away by the current — and as he was carried off, he tossed the blooms to her and cried, “Forget me not!” Today the flower remains a global emblem of memory and remembrance.
