    You must look closely - but spring is showing up around the ISU campus this week. The tiny blooms of Cornus mas are open near Honors and Lago buildings. Hope you enjoyed the first day of spring! #cornusmas #dogwood #horticulture #iowa_state_ext_anr #iastateu #iowa365 #iowa #spring #iowastateuniversity #isucals

    Last snow? It certainly does not feel like spring break here! As a reminder - gently brush off heavy snowfall from evergreens to prevent limbs from breaking. #lastsnowfall #boxwood #horticulture #iastateu #iowa #springbreak

    Look at the beautiful centerpieces made by some of the Hands-on Horticulture (Hort122) students this week. Great job! #floraldesign #horticulture #centerpiece #horteducation #iastateu #iastate_cals

    Small signs of spring are appearing everywhere - inside the greenhouses some seedlings are up! #seedlings #seedgermination #iastateu #horticulture #iastate_cals #iowastateuniversity
