A tropical plant that is prized for its unique pink foliage, Caladium is simply irreplaceable in containers. Plus, you can bring them indoors as houseplants when temperatures start to dip! The variegated leaves display an intense rosy hue at the center that lightens as it grows closer to the margin, which is a deep green. You’ll even see some white in a Caladium leaf. Caladium Radiance is perfect for containers in sun or shade. They are heat tolerant and add unique visual interest to containers and large planters.
Caladium is a favorite “thriller” choice for containers thanks to its variegated colors, wide leaves and upright habit. You won’t see leaves as colorful as this on any other plant. It’s also a popular house plant, so with Caladium Radiance, you can get the best of both worlds!
Heart to Heart Radiance Caladium Care
Caladium is adaptable to different light conditions, but would like some shade in areas where the sun can get intense. Your particular growing region will dictate the planting time and sun needs for your Caladium. Planting can be done anywhere between spring and early summer, depending on your last frost date and spring temperatures. Soil temperatures must be above 50°F. Caladiums grown in hot, sunny regions like the Southwest and Midwest will require more shade than those grown in the Northeast and Northwest, for instance. Caladiums require a small amount of balanced fertilizing every month, as well as well-draining soil and consistent moisture.
Caladiums are well known as indoor plants, and can be brought indoors after spending the summer outside. Check your plant to be sure it is healthy and pest-free before bringing indoors. They thrive in a warm, sunny location like a windowsill. Because they are tropical plants, they require warmth and humidity. Try misting your plant frequently or keeping it on a pebble plant to provide humidity, especially in the winter when indoor air is dry.
Heart to Heart Radiance Caladium Spacing
One healthy Caladium per container is usually perfect for adding the color and texture you need. However, if you have a large container or planter box, you can plant several Caladiums to get a big impact. Try planting them about 4” apart in your large planters to give them space to grow, but enjoy a lush display of their big, variegated leaves. Caladium can be planted in clusters in garden beds, but be sure to wait until soil temperatures are between 50-65°F to plant them. If planting Caladium into a garden bed, allow for 6-8” space between each tuber.
