Wayside Gardens Caladium Sweetheart Bulbs

While many Caladiums prefer deep shade, the 'Sweetheart' variety is specifically bred for vigor and can handle summer sun better than most. However, they still perform best in part to full shade settings to maintain their vibrant pink coloration.

Plant the bulbs in a rich, well-draining potting mix once soil temperatures reach 75-85°F. Ensure the container has adequate drainage holes, as Caladiums enjoy moisture but will rot in waterlogged soil.

Yes, they make excellent houseplants. When grown indoors, provide them with bright, indirect light and keep them in a warm environment to mimic their natural tropical growing conditions.

Since these grow to a mature width of 2 feet, a single bulb is sufficient for a 10-12 inch pot. For larger planters or baskets, you can space them 8-10 inches apart to create a fuller, lush display.

In zones colder than 9, these bulbs are not winter-hardy. You can treat them as annuals, or dig up the bulbs in the fall before the first frost, store them in a cool, dry place, and replant them the following spring.
