Color That Likes It Hot

Color That Likes It Hot

By Pamela Crawford, author, Easy Container Gardens

Pink and grey combine to make an attractive but tough, heat-tolerant combination in this blue ribbon arrangement. It required nothing but water during its entire six month lifespan. This was our first experience with silver licorice plant and I was quite thrilled that it breezed through our hot summer.

This pot is lightweight fiberglass, so I was able to carry it around a nursery in search of plants that looked good with it. Fiberglass is an excellent container material. It is durable (think about it - boats are made of fiberglass!), easy to clean, and available in attractive finishes, like this grey one.

Cultural Information

Light: Full sun to light shade.

Season: Spring and summer in areas where temperatures range from 65 to over 100 degrees.

Lifespan: This arrangement is happy in this size pot for about five to six months. Be sure that the caladiums are dwarfs, or they will quickly outgrow the dipladenia.

Although dipladenia is classed as a perennial, I have never had much luck with it living more than one season in the ground - even in zone 10 - where it is supposed to thrive. Use it as an annual.

Care: Easy! No trimming necessary. Fertilize on planting day with a slow-release mix.

Water: Water thoroughly when the plants show signs of wilt, or the soil feels dry when you push your fingertip into the potting mix. I watered this twice a week in spring and every day in summer.

Troubleshooting: The paint chipped off the pot after three years. If this happens to you, take it to your local paint store so they can match up the color. Touch up the paint following the manufacturer’s instructions.

The dipladenia went out of bloom but only for a very short time.

Caladiums are poisonous.

Planting Plan: Plant the dipladenia along the back edge, centered. Plant the caladium along the front edge, surrounded by the silver licorice plant. Be sure to plant in good-quality potting mix, not garden soil, top soil, or potting soil, which can kill the plants.
