On all occasions except during cold weather crotons are gorgeous and grand plants for decorations, but they must not be chilled. My experience is that if a croton is exposed to a temperature of 40 degrees for an hour it will drop its handsome leaves, and in the winter we sometimes expose our palms and dracaenas to a lower temperature than that without much or any damage. So large plants of crotons had better be kept at home.
Small plants of crotons are now raised and sold almost as cheaply as fuchsias or geraniums, and if you do lose them you have possibly charged enough for the job to consider it no loss. For a mantel decoration with vases of flowers, or for plants for a banquet table nothing can be finer than the many grand varieties of crotons.
