Taxonomic Information

Appearance

Lonicera plants come in a variety of sizes and shapes, ranging from low-growing shrubs to tall climbing vines. They have opposite leaves and tubular flowers that are usually white or yellow, but can also be pink, red, or orange. The flowers are followed by berries that are typically red, blue, or black. Lonicera plants are deciduous or evergreen, depending on the species, and can be grown as perennials or annuals.

Care Guide

Proper care is essential for the health and growth of Lonicera plants. Here are some tips:

• Water: Lonicera plants prefer moist but well-drained soil. Water them deeply once a week, and more often during hot or dry weather.
• Fertilization: Fertilize Lonicera plants in the spring with a balanced fertilizer, and then again in midsummer with a high-phosphorus fertilizer to encourage blooming.
• Soil: Lonicera plants thrive in fertile, humus-rich soil that is slightly acidic.
• Sunlight: Lonicera plants prefer full to partial sun, but some species can tolerate shade.
• Hardiness Zones: Lonicera plants are hardy in USDA zones 3-9, depending on the species.

Common Pests & Diseases

Lonicera plants are susceptible to a few common pests and diseases:

• Aphids: These small, soft-bodied insects feed on the sap of plants and can cause distortion and discoloration of leaves. Use insecticidal soap or neem oil to control them.
• Spider mites: These tiny pests can cause yellowing and stippling of leaves. Use insecticidal soap or neem oil to control them.
• Powdery mildew: This fungal disease causes a white, powdery coating on leaves. Remove infected leaves and use a fungicide to control the disease.
• Leaf spot: This fungal disease causes brown spots on leaves. Remove infected leaves and use a fungicide to control the disease.

Habitat

Lonicera plants are found in a wide range of habitats, from forests and meadows to wetlands and deserts. They are native to the Northern Hemisphere, including North America, Europe, and Asia. Some species are invasive in certain areas and can outcompete native plants.
