Ixora plants like bright light, but keep them away from direct sunlight in summer.  These plants feature large clusters of red, yellow, white, or orange flowers that emerge like puffballs from the evergreen leaves in the summer. An Ixora is an out-of-the-ordinary houseplant, but a well-grown specimen attracts attention. Ixora plants are small shrubs that grow in subtropical regions. Although they are relatively easy to grow outdoors, keeping an Ixora happy and blooming inside is a challenge even for an experienced gardener.
