You’ve never seen a caladium like this. Midnight Oil™, a first-of-its-kind strap-leaf Heart to Heart® caladium, brings an entirely new mood to the garden with its near-black foliage. Each arrow-shaped leaf blends deep green and rich red tones, edged with undulating margins that catch the light. In part shade it glows with subtle depth, but in direct sun the color intensifies to a striking charcoal black, creating an unforgettable presence even from a distance. Through spring and summer the foliage stays dark and sultry, then softens in autumn as its red and green undertones emerge. Vigorous and full, Midnight Oil thrives in containers, hanging baskets, and landscapes, where it lends an elegant, dramatic edge.

12-14 inches tall and 10-14 inches wide at maturity
Hardy in zones 10-11, be sure to check your USDA zone to ensure success
Plant in part to full sun (4+ hours daily)
Space plants 10-14 inches apart for best results
Maintains near black foliage with deep green and red tones from spring to frost
Great for borders, containers, landscapes, mass plantings
Resists deer
Adaptable as a houseplant, foliage interest, heat tolerant, deadheading not necessary

Care: If you live in a northern climate, be careful not to plant too early in spring as temperatures below 60 degrees F will chill and stunt plants. Caladiums like to be moist at all times so avoid allowing them to dry out. Fertilize with Proven Winners Water Soluble Plant Food at ¼ - ½ strength every week throughout the season. Houseplant: Caladiums can also be grown as houseplants where they prefer bright light or a sunny window. Keep the temperatures above 65 degrees F for best growth and leaf size, and a pebble tray or frequent misting can help to keep the humidity up around your plants.
