    Yes, it IS always GREENER with Proven Winners.

    Described as nothing less than elegant, '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 intermediate plant in the landscape. It is adapted to both sun and shade. 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.

    Caladiums can be a very nice windowsill or sunroom plant and for much of the United States and certainly in Canada this might be the best use for Caladiums. Since they are tropical they need to have warmth and humidity, try to always keep the temperatures above 65 F for best growth and leaf size, and a pebble tray or frequent misting can help to keep humidity up around your plants. If you live in a northern climate, be careful not to plant too early in spring as temperatures below 50F will chill and stunt plants, normal indoor temperatures should be fine and winter heaters usually dry things out a bit too much. So this can be a good guide for when to grow these Caladiums, when you turn the heater off for the summer.

    Plant tubers pointed end facing upwards, so the tuber is about 2” below the soil level, the roots form on the top of the tuber , so you need to plant them deep enough that roots have room to grow, but not too deep because it delays new leaves and weakens the plant. If your plants are already growing in pots when you purchase them, plant them about ½” deeper when you transplant them to make sure the tubers have room to keep growing.

    Caladiums do not need a lot of fertilizer, about ¼ of what most folks feed their flowering annuals, and too much fertilizer can burn the leaves especially the white portions of the leaf. So just fertilize with ¼ the strength what you normally do for your flowers and apply weekly or every other week.

    Keep plants in a sunny to partly sunny location and avoid burning hot southern exposures especially at higher altitudes.

    Keep soil in your pots moist at all times, wilting will cause leaves to yellow and drop, so just check to make they do not dry out!


    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. 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 to help you succeed.


    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


    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. 


    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


    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 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.

    • 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.
