For ages, our holidays have become synonymous with flowers; Christmas time brings poinsettias, Easter brings lilies, and Halloween brings pumpkins. Recently, even house plants have gained popularity during the pandemic as they reminded us of the world while we were quarantined away from it. They bring much joy and beauty to our lives, but do you know which flowers and plants are safe to have around with our four-legged friends? With Spring around the corner, now is the time to change that!
