If you prefer eating with seasonal produce then it’s good to keep in mind that rhubarb is in season from late winter to early summer. I typically see it in the grocery store in the spring and summer. Of course, if you have an excess amount grown during the season then you can freeze it for making delicious fall recipes or rhubarb crunch any time of year.  My rhubarb here in Northern California seems to grow year round, so you might have a longer growing season if you live in a more temperate climate.
