Compare these two plants side by side — care needs, key differences, and which is right for your home.
Dieffenbachia
Dieffenbachia seguine
Dieffenbachia seguine, commonly known as Dumb Cane, is a popular ornamental plant prized for its large, decorative leaves. It's a herbaceous perennial that typically grows upright with a thick, cane-like stem. The leaves are broad, ovate, and variegated with patterns of green, cream, yellow, or white. While it can grow outdoors in tropical climates, it's primarily cultivated as a houseplant for its attractive foliage. People grow it for its ease of care and ability to brighten indoor spaces, although its toxicity requires caution.
Pineapple Guava
Acca sellowiana (syn. Feijoa sellowiana)
Pineapple Guava is an evergreen shrub or small tree, typically grown outdoors for its ornamental value and edible fruit. It features attractive gray-green foliage, showy red and white flowers with edible petals, and egg-shaped, green fruit with a sweet, aromatic flavor reminiscent of pineapple and guava. While it can be grown in containers, it thrives best outdoors where it can reach its full potential. People grow it for its unique fruit, attractive appearance, and relatively low maintenance once established.

An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work, but the plant may not grow as quickly.
How do I care for Dieffenbachia?
Dieffenbachia thrives in bright, indirect light; avoid direct sunlight to prevent leaf burn. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain high humidity by misting regularly, using a humidifier, or placing the plant on a pebble tray.
How do I propagate Dieffenbachia?
Dieffenbachia can be propagated through stem cuttings, division, or air layering. For stem cuttings, take a healthy stem cutting with at least one node. Allow the cut end to callous over for a day or two, then plant it in moist potting mix or place it in water until roots develop.
Pineapple Guava
What are the light requirements for Pineapple Guava?
Pineapple Guava thrives in bright, indirect light indoors. A south-facing window is ideal, but if the light is too intense, filter it with a sheer curtain. Insufficient light can lead to leggy growth, reduced flowering, and less fruit production. If natural light is limited, supplement with grow lights.
How do I care for Pineapple Guava?
To successfully grow Pineapple Guava indoors, provide bright, indirect light, ideally near a south-facing window. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain moderate humidity levels by misting regularly or using a humidifier.
