Four O'Clock vs Hop Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Four O'Clock
Mirabilis jalapa
Mirabilis jalapa, commonly known as the Four O'Clock flower, is a bushy, herbaceous perennial typically grown as an annual in cooler climates. It's known for its trumpet-shaped flowers that open in the late afternoon or early evening, releasing a sweet fragrance. The flowers come in a variety of colors, including pink, red, yellow, white, and multicolored variations. It grows from tuberous roots and can reach a height of 1-3 feet. It is primarily grown outdoors in gardens and borders for its vibrant colors and evening fragrance. It is not ideally suited as an indoor plant.
Hop
Humulus lupulus
Humulus lupulus, commonly known as hops, is a vigorous, herbaceous perennial climbing vine. It's best known for its use in brewing beer, where the female flower cones (strobiles) impart bitterness, flavor, and aroma. Hops are dioecious, meaning male and female flowers are on separate plants; only female plants produce the cones used in brewing. The plant features rough, twining stems that can grow several meters in a single season. While primarily an outdoor plant, some enthusiasts attempt to grow it indoors, which presents significant challenges due to its light and space requirements.

💡 Pro Tips For Comparing These Plants
Four O'Clock Care Tips
Four O'Clocks are primarily outdoor plants and require full sun to thrive. Growing them indoors is challenging due to their high light requirements and potential for pest infestations. They also spread via tuberous roots, which can quickly outgrow a container. Indoor flowering is unlikely.
- Plant in well-draining soil to prevent root rot.
- Provide full sun for best flowering.
- Deadhead spent flowers regularly to encourage more blooms.
- Protect from strong winds, which can damage the delicate stems.
- Monitor for pests like aphids and treat promptly.
Hop Care Tips
Hops are challenging to grow indoors due to their intense light requirements and vigorous growth habit. They need a large container, a strong support structure, and consistent care. Even with optimal conditions, indoor growth may be limited. Primarily an outdoor plant.
- Provide a strong trellis or support structure for the vines to climb.
- Water deeply and regularly, especially during hot weather.
- Monitor for pests and diseases and treat promptly.
- Fertilize regularly during the growing season.
- Harvest the cones when they are papery and fragrant.

❓ Frequently Asked Questions — Comparing These Plants
Four O'Clock
What are the light requirements for Four O'Clock?
Four O’Clocks thrive in full sun, needing at least 6 hours of direct sunlight daily to produce abundant blooms. A sunny location encourages strong growth and vibrant flower colors. While they can tolerate partial shade, reduced sunlight will result in fewer flowers and leggier growth.
How do I care for Four O'Clock?
Four O’Clocks are relatively easy to care for. Plant them in well-draining soil in a location that receives at least 6 hours of sunlight daily for optimal blooming. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season with a balanced fertilizer or one formulated for blooming plants to encourage abundant flowering.
How do I propagate Four O'Clock?
Four O’Clocks can be propagated through seeds, tubers, or stem cuttings.
Hop
What are the light requirements for Hop?
Hop vines thrive in full sun, requiring a minimum of 6-8 hours of direct sunlight each day for optimal growth and cone production. Insufficient sunlight can lead to weak growth, reduced cone yield, and increased susceptibility to diseases. Choose a location in your garden that receives ample sunlight throughout the day. If you live in a particularly hot climate, some afternoon shade may be beneficial to prevent scorching of the leaves. When growing hops indoors (less common), use grow lights to supplement natural sunlight. Rotate the plant periodically to ensure even light exposure on all sides.
How do I care for Hop?
Hop vines require a sunny location with at least 6-8 hours of direct sunlight daily. Plant in well-draining soil enriched with compost or other organic matter. Provide a sturdy trellis or support structure for the vines to climb. Water deeply and regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Fertilize in early spring with a balanced fertilizer, and again mid-summer. Prune in late winter or early spring to remove dead or weak bines and encourage new growth. Monitor for pests such as aphids and spider mites, and treat as needed. Harvest the cones in late summer or early fall when they are fragrant and slightly sticky. Mulch around the base of the plant to retain moisture and suppress weeds. Regularly inspect the vines and adjust support if needed to accommodate their rapid growth.
How do I propagate Hop?
Hops are easily propagated through stem cuttings or layering. For stem cuttings, take 6-8 inch cuttings from healthy bines in spring. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in well-draining potting mix and keep it moist. Roots should develop in a few weeks. For layering, bend a low-growing bine to the ground and bury a section of it, leaving the tip exposed. Secure the buried section with a rock or garden staple. Keep the soil moist. Once roots have formed, sever the layered section from the parent plant and transplant it. Both methods are effective for producing new hop plants. Ensure the new plants receive adequate sunlight and support.
