Dandelion
Taraxacum officinale
Overview
The most maligned and most useful plant in the modern lawn. Every part is edible and medicinal. The deep taproot mines minerals from subsoil, accumulating calcium, potassium, and iron in the leaves. One of the earliest spring nectar sources for emerging pollinators. Leave a few in your lawn for the bees.
Growing Conditions
How to Grow Dandelion
Dandelion (Taraxacum officinale) is a taprooted perennial that grows to about 12 inches tall and 12 inches wide.
To grow dandelion, give it full sun. It is hardy across USDA hardiness zones 3–10. Plant it in tolerates almost any soil; prefers loose, fertile loam, at a slightly acidic pH of 6–7.5. It does best with even, moderate watering.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its yellow flowers appear from March through October, offering high value to pollinators. It is a plant for the low-water garden — patient through heat, slow to complain.
Companion Planting & Soil
Dandelion grows well alongside fruit trees (mines minerals) and most garden plants.

Planting Calendar
When to sow, transplant, and harvest by growing zone.
| Zone | Action | Months | Notes |
|---|---|---|---|
| Cold (1-2) | Harvest | Apr — Jun | Best leaves in spring before flowering — least bitter |
| Cold (1-2) | Harvest | Sep — Oct | Fall harvest of roots after frost concentrates inulin |
| Cool (3-4) | Harvest | Mar — May | Pick young leaves and flower buds; roots all season |
| Moderate (5-7) | Harvest | Mar — Nov | Year-round harvest; young leaves best |
| Moderate (5-7) | Bloom | Mar — Jun | Flowers used for wine, fritters, syrup |
| Warm (8-9) | Harvest | Jan — Dec | Available year-round; harvest from un-sprayed lawns and meadows |
| Warm (8-9) | Bloom | Feb — May | Early spring bloom; critical food source for emerging pollinators |
| Hot (10+) | Harvest | Nov — Apr (wraps) | Cool-season growth; dormant in peak summer |
Uses
In the Kitchen
In the kitchen, dandelion turns up in more than one form: young leaves in salads (bitter, like radicchio); flowers fried as fritters, fermented into wine, or boiled into syrup; roasted root as coffee substitute.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: leaves are diuretic and rich in potassium (replaces what diuretics deplete); root supports liver detoxification — used in herbal bitters; traditional spring tonic in many cultures. These are traditional uses, not medical advice.
Beyond the Garden
Dandelion earns its keep past the plate, too: deep taproot breaks up compacted soil; critical early-season food for honeybees and native bees.
Safety Notes
Confusion with similar yellow-flowered plants is possible — verify ID. Only harvest from un-sprayed areas (no herbicides, no roadsides).
