Firethorn vs Pineapple Guava Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Firethorn
Pyracantha coccinea
Pyracantha coccinea, commonly known as Firethorn, is a thorny evergreen shrub typically grown outdoors. It is characterized by its dense, bushy growth habit and vibrant displays of bright red or orange berries in the fall and winter. The plant features small, dark green, glossy leaves and clusters of white flowers in the spring. Firethorn is primarily cultivated for its ornamental value, providing year-round interest with its foliage and colorful fruit. It is often used as a hedge, screen, or espaliered against walls. While it can technically be grown in a container, it is not ideally suited for indoor environments due to its need for full sun and potential size.
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.

❓ Frequently Asked Questions — Comparing These Plants
Firethorn
What are the light requirements for Firethorn?
Firethorn requires at least six hours of direct sunlight per day to thrive and produce an abundance of flowers and berries. While it can tolerate partial shade, insufficient light will result in reduced flowering and berry production. A location with morning sun and afternoon shade is ideal in hotter climates to prevent scorching. When planting Firethorn, choose a spot that receives ample sunlight throughout the growing season. Insufficient light can also lead to leggy growth and weakened stems. If growing Firethorn indoors, place it near a sunny window or supplement with artificial light. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Firethorn?
Firethorn thrives in well-drained soil and full sun to partial shade. Water regularly, especially during dry periods, but avoid overwatering. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant flowering. Prune annually to maintain shape, remove dead or damaged branches, and encourage berry production. Firethorn is relatively drought-tolerant once established. Monitor for pests such as aphids and spider mites, and treat promptly if necessary. Provide support for young plants, especially if training as an espalier. Mulch around the base of the plant to retain moisture and suppress weeds. Firethorn is generally hardy but may require protection from severe frost in colder climates. Ensure good air circulation to prevent fungal diseases. Regular deadheading of spent flowers can encourage further blooming.
How do I propagate Firethorn?
Firethorn can be propagated through several methods, including stem cuttings and layering. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist. Roots should develop in 4-6 weeks. Layering involves bending a low-growing branch to the ground and covering a portion of it with soil. Once roots develop, the layered branch can be separated from the parent plant. Division is possible for established plants by carefully separating the root ball into smaller sections, ensuring each section has healthy roots and stems. Replant the divisions in well-draining soil and water thoroughly.
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. Use a well-draining potting mix formulated for fruit trees. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer.
How do I propagate Pineapple Guava?
Pineapple Guava can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch semi-hardwood cutting in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist and humid. Roots should develop in 6-8 weeks.
