The gradually warming weather is a sure sign of one thing: D.C.’s famous cherry trees will be blooming soon. The National Cherry Blossom Festival begins March 20.

In honor of the humble flower, we want you to send in haikus (the three-line poems that have five syllables in the first, seven in the second and five in the third). The author of the winning verse receives a gorgeous new coffee table book, “Cherry Blossoms,” the official book of the National Cherry Blossom Festival.

We’ve teamed up with the upcoming poetry festival Split This Rock for the judging; area poets Venus Thrash and Jose Padua, who perform at the festival March 23-24, will pick our winner, whom we’ll announce here on the Going Out Gurus blog on March 22. So be sure to get your entries in soon.

Submit your odes in the comments below and recommend other readers’ poems that you like. Or you can tweet your poems to @goingoutguide with hashtag #blossomhaiku. Check out the photo gallery above or the comments to see submissions we’ve already received. And here are a couple of fun old photos to get you in the spirit:
