Adelonema wallisii thrives in partial sunlight with a preference for dappled shade. A balanced exposure offers enough light for photosynthesis without the stress of intense direct sun.

King of hearts (Adelonema wallisii)

Also known as: Adelonema wallisii

Adelonema wallisii (synonym Homalomena wallisii ) is a species of flowering plant in the family Araceae native to Venezuela, Colombia, and Panama. It reaches about 15 cm in height but with a much wider spread. The leaf blades are elliptic to ovate-oblong in shape about 13 to 20 cm in length, on rather short stalks, arching or recurving, bright-green with a markings of a marbled yellow.

What Is the Ideal Temperature Range for King of hearts?

Ideal Temperature: 65 ~ 75℉

For optimal growth, Adelonema wallisii thrives in temperatures between 65°F and 75°F. This range mimics their natural tropical environment, providing warmth without excessive heat. Consistent temperatures within this range help maintain the plant's metabolism, ensuring healthy foliage and growth while preventing stress-induced conditions.

What Soil is Best for King of hearts?

Soil type: Loam, Sandy loam

Soil PH: 6.5 ~ 7.5

Adelonema wallisii prefers a well-draining soil to prevent root rot. The ideal choice is loam or sandy loam, which allows excess water to quickly percolate away, helping the roots to breathe and stay healthy. This plant loves nutrient-rich soil that provides ongoing nourishment. A soil mix that incorporates compost or well-rotted organic matter helps ensure the plant receives essential nutrients for vibrant growth and foliage. While drainage is crucial, the soil should also be able to retain some moisture. A blend that balances drainage with moisture retention, such as adding peat moss, keeps the plant hydrated without drowning its roots.

How to Fertilize King of hearts?

Fertilizer type: Balanced

When fertilizing Adelonema wallisii, use a balanced liquid fertilizer diluted to half strength. Apply 5 milliliters of diluted liquid fertilizer per liter of water. This amount ensures nutrients are available without risking root damage.

How to Prune King of hearts?

Pruning Time: Spring, Summer

Start by identifying any yellowing, damaged, or dead leaves and gently remove them by cutting close to the main stem. This helps prevent disease and pest infestations while also improving the plant's appearance. Next, trim any overgrown or leggy stems to maintain a compact shape, making cuts just above a leaf node. This encourages branching and fuller growth. Always use sterilized, sharp scissors or pruning shears to prevent infection and make clean cuts. More About Pruning Techniques→

How to Propagate King of hearts plant?

Propagate Time: Spring, Late spring, Early spring, Summer

Select a healthy stem from the parent plant, avoiding any signs of disease or damage. Cut the stem at least 4-6 inches long, ensuring you have several nodes as these are critical for new root formation.

Remove the lower leaves from the cuttings to prevent rot when inserted into the soil. Dip the cut end into rooting hormone to stimulate the root growth, which is particularly helpful for difficult-to-root species.

Insert the prepared cuttings into a potting mix composed of peat and perlite to ensure aeration and moisture retention. Keep the cuttings in a warm area with indirect sunlight to enhance the rooting process.

How to Repot King of hearts plant?

Repotting frequency: Every 1-2 years

Adelonema wallisii shows signs it's time for repotting when you observe roots emerging from the drainage holes, or the plant appears to be oversized for its current pot. If growth seems to have slowed despite regular care, these are clear signals that repotting is necessary. Choose a time during the growing seasons, like spring or summer, to minimize stress.

Select a pot that is one size larger than the current one, with ample drainage holes. Using a pot that’s slightly bigger prevents water from sitting too long and causing root rot, yet provides enough room for growth, supporting a healthier, more vigorous plant.

Opt for a well-draining aroid mix, ideally composed of peat, perlite, and orchid bark. This combination ensures moisture is retained without waterlogging the roots, offering the perfect balance for Adelonema wallisii to flourish in its new pot.
