Professional Growing Information I haven't grown caladiums before and what an introduction - this one is stunning! I have it in a pot by itself in a mostly shady location and it has performed beautifully. It's not fussy at all and gets many compliments. I look forward to growing this next year as well.

Features
Described as nothing less than elegant, Heart to Heart White Wonder is a beautiful lance-leaved (strap) variety that can stand full sun. Due to its stature, 'White Wonder' makes an excellent border to intermediately plant in the landscape. It is adapted to both sun and shade. These white caladiums are also generally considered to be houseplants where they prefer bright light or a sunny window.
Caladiums can be an irritant if ingested. The ASPCA has more information on which plants may be harmful.

Since Caladiums prefer heat and humidity and do not tolerate cold, soggy soils, for most gardeners who live in the north will have best results in containers, as the soil in pots or planters warms up faster and has better drainage so plants will not become soggy. Remember for best growth always keep the temperatures above 65 F.
A ¼ - ½ strength fertilizing every week or every other week is fine throughout the season, too strong a fertilizer can burn leaves, and since the leaves last all season you want to keep them looking fresh. Heart to Heart white caladiums like to be moist at all times so avoid allowing them to dry out as it also causes leaves to yellow and drop.
Where the Caladiums will do best depends a lot on your location within the US, since sunlight intensity varies depending on where you live. Here's a quick reference to help guide you to success.
Region
When to Plant
Sun or Shade
Containers or in the garden
NW & NE United States & Canada
Early summer
Full sun - light shade.
Caladiums do best in containers in this part of the country and usually need to be in a protected warm location for best results. Like a sunroom or warm patio setting. If growing outdoors select the warmest protected locations in the garden.
SW United States
Spring
shade to light shade only
Containers may be easiest but a shady, cool garden spot can also be lovely. Watch your watering to keep the plants from drying out.
Midwest
Late Spring
Light shade
Containers are likely best, but a late spring planting into a protected shade flower bed will also be fine.
SE United States
Spring
Shade to sun
Both containers and garden plantings work fine, in the deep south Caladiums may even come back the following year if kept dry over the winter.

I live in southern Michigan. I planted White Wonder caladiums outside in a sunny location. They did reasonably well, but despite the claim that they can take full sun, there was some burning. However, damaged leaves were quickly replaced by new leaves, and overall they made a nice display. I also found that my plants did not grow as tall as advertised; mine were not more than a foot tall. I liked them and would plant them again, but in spot with less afternoon sun.

I bought a package of four corms from Home Depot this past spring. When I found out from Garden Answer YouTube channel of the new caladiums that can be in full sun and shade, i was thrilled. I told myself that I would plant them and bring them inside the house during fall and winter. I’m glad I did. So far, all the caladiums are doing amazingly even though they needed a little time to adjust indoor when I brought them in. I have them by south facing windows.

This plant is unbelievably beautiful and has grown so big and healthy. It is in the Florida sun all day and I mean hot direct sun all day! I am so happy with it and highly recommend it.
