Typical Growth Conditions of Cyanea lanceolata ssp. calycina
Cyanea lanceolata ssp. calycina, commonly known as "haha" among native Hawaiians, is a plant species that is endemic to Hawaii. This species typically grows in wet and mesic forests at elevations between 800-2,000 meters. Below are the typical growth conditions required for Cyanea lanceolata ssp. calycina to thrive.
Light Requirements
Cyanea lanceolata ssp. calycina requires bright, filtered light to grow. This species is adapted to growing under the shade of taller trees within the forest. Direct sunlight can be harmful to the plant and cause leaf scorching. Partial shade or dappled sunlight is ideal for the growth of this species.
Temperature Requirements
The temperature requirements for Cyanea lanceolata ssp. calycina are relatively specific and must maintain cool, stable temperatures ranging between 18-21°C (64-70°F). The temperature range of the forests within Hawaii's mountains where the species naturally grows typically stays within this ideal range.
Soil Requirements
Cyanea lanceolata ssp. calycina requires well-draining soil with high organic matter content. These plants grow best in nutrient-rich soils that retain moisture while still being well-draining. The ideal soil pH for Cyanea lanceolata ssp. calycina ranges between 5.0-6.5. Additionally, this species requires consistent moisture, it is important to avoid letting the soil dry out completely.
Cultivation Methods for Cyanea lanceolata (Gaud.) Lammers, Givnish & Sytsma ssp. calycina (Cham.) Lammers, Givnish & Sytsma
Cyanea lanceolata (Gaud.) Lammers, Givnish & Sytsma ssp. calycina (Cham.) Lammers, Givnish & Sytsma is a stunning plant that requires proper cultivation for optimal growth. The plant prefers partial shade and well-draining soil for healthy growth. When cultivating the plant, make sure you select a spot with good air circulation to prevent fungal diseases.
The ideal temperature range for Cyanea lanceolata (Gaud.) Lammers, Givnish & Sytsma ssp. calycina (Cham.) Lammers, Givnish & Sytsma is between 60-70°F. The plant is sensitive to cold temperatures and may not survive in areas with temperatures below 45°F.
Watering Needs
Cyanea lanceolata (Gaud.) Lammers, Givnish & Sytsma ssp. calycina (Cham.) Lammers, Givnish & Sytsma requires moderate watering. Over-watering or under-watering can lead to stunted growth or plant death. Water the plant only when the soil is dry to the touch. The plant prefers regular misting to create a humid environment, which promotes healthy growth.
Fertilization
Cyanea lanceolata (Gaud.) Lammers, Givnish & Sytsma ssp. calycina (Cham.) Lammers, Givnish & Sytsma requires regular fertilization to enhance growth and flowering. Fertilize the plant every two weeks during the growing season using a balanced liquid fertilizer. Always follow the manufacturer's instructions when fertilizing the plant.
Pruning
Cyanea lanceolata (Gaud.) Lammers, Givnish & Sytsma ssp. calycina (Cham.) Lammers, Givnish & Sytsma requires minimal pruning. The plant produces new leaves from the center of the rosette, and the older leaves may yellow and die. Prune off the yellow leaves carefully to prevent damage to the healthy foliage, using sharp and clean scissors. Additionally, you can remove spent flower spikes to encourage more blooms.
Propagation of Cyanea lanceolata ssp. calycina
Cyanea lanceolata ssp. calycina, also known as the lobelia family, is a stunning perennial plant that is native to Hawaii. While propagation of this plant can be challenging, it is highly rewarding, especially if one follows the necessary instructions for success. The plant is commonly propagated by seeds, cuttings, and division.
Propagation by Seeds
If you choose to propagate Cyanea lanceolata ssp. calycina by seeds, start by collecting the ripe seed pods from the parent plant and allow them to dry. After this, remove the seeds from the husks and clean them. Sow the seeds in small pots filled with compost and keep the pots in warm, bright, and moist conditions. Germination usually occurs within a few weeks.
Propagation by Cuttings
Propagating by cuttings is another method that can be employed to propagate the Cyanea lanceolata ssp. calycina. Start by taking cuttings of new growth from the parent plant and remove the lower leaves from the cutting. Dip the cut ends into rooting hormone and place them in pots filled with a well-draining potting mix. Keep the cuttings in a moist, bright, and warm environment until they begin to put forth new growth.
Propagation by Division
This method of propagation of the Cyanea lanceolata ssp. calycina involves dividing the parent plant into smaller sections, each with its roots. To do this, start by lifting the parent plant out of the soil and carefully examine and separate the roots and stems into small pieces. Place each piece in a well-draining potting mix and care for them as needed.
Disease Management
Cyanea lanceolata ssp. calycina is a relatively disease-resistant plant but can still be affected by some fungal diseases. Here are some common diseases that might affect the plant and ways to manage them.
Leaf Spot
Leaf spot is a fungal disease that causes small, circular spots on the foliage. To manage this disease, remove infected leaves and dispose of them properly. Also, avoid watering from overhead and practice good sanitation to prevent the spread of the disease.
Rust
Rust is a fungal disease that causes orange or yellow spots on the underside of the leaves. To manage rust, remove infected leaves and dispose of them properly. Also, avoid overhead watering, and space the plants to promote good air circulation.
Pest Management
Cyanea lanceolata ssp. calycina can be affected by various pests that can damage the flowers, foliage, and stems. Here are some common pests that might affect the plant and ways to manage them.
Slugs and Snails
Slugs and snails are common pests that feed on the foliage and flowers of the plant, causing significant damage. To manage these pests, handpick them and dispose of them properly. Also, you can use a slug and snail bait product, following the instructions carefully.
Spider Mites
Spider mites are tiny pests that suck the sap from the leaves of the plant, causing yellowing, spotting, and leaf drop. To manage spider mites, wash the leaves with a strong jet of water or use a natural predator like ladybugs. Also, avoid over-fertilization, which can make the plant more vulnerable to infestation.
