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.
Hellebore
Helleborus orientalis
Helleborus orientalis, commonly known as Lenten Rose, is a clump-forming, evergreen perennial prized for its nodding, cup-shaped flowers that bloom in late winter to early spring. The flowers come in a range of colors, including white, pink, purple, and speckled varieties. It typically grows to a height and spread of 1 to 1.5 feet. While it can be grown in containers, it is primarily an outdoor plant that thrives in shaded garden beds. People grow it for its early-season blooms, providing color when little else is flowering, and its tolerance of shade.

❓ 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.
Hellebore
What are the light requirements for Hellebore?
Hellebores thrive in partial to full shade. In hotter climates, providing complete shade is crucial to prevent leaf scorch. Morning sun followed by afternoon shade is an ideal scenario. The amount of light they receive directly affects their flowering potential. Insufficient light can result in fewer blooms, while too much direct sunlight can damage the foliage.
How do I care for Hellebore?
Hellebores thrive in partial to full shade, requiring protection from intense sunlight. They prefer well-drained, fertile soil that is rich in organic matter. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Remove old or damaged foliage in late winter to allow new growth and flowers to emerge.
How do I propagate Hellebore?
Hellebores are primarily propagated by division in early spring or fall. Carefully dig up the plant and separate the root clump into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-drained soil and water thoroughly. Seed propagation is also possible, but it can be slow and the resulting plants may not be true to the parent plant.
