Rhubarb is typically in season in spring through early summer , with peak availability from about April to June in most temperate regions.

Quick Scoop

  • In many areas, the main rhubarb season runs from April to June.
  • Some cooler regions (like parts of Alaska or the far north) can have rhubarb right through summer , sometimes into July or even later.
  • In milder climates (like coastal California), field rhubarb can start as early as February.
  • Greenhouse or “hothouse” rhubarb can show up in late winter , 1–2 months before outdoor rhubarb, but it’s more expensive.
  • Many gardeners and extensions suggest harvesting from early spring until about mid-summer (roughly March/April to June/July, depending on your region).

If you’re shopping, your best bet for fresh, local rhubarb is those bright, cool spring weeks when strawberries also hit their stride – perfect for that classic strawberry–rhubarb pie.
