Canna lilies are striking ornamental plants. They can grow up to 2-8 feet. This depends on the variety. Tropicana is known for its multi-colored leaves. President is prized for its large, red blooms.
Canna lilies are heat-loving plants. They do well in USDA hardiness zones 7-10. However, with proper care, you can also grow them as annuals in cool regions.
Consider some factors when selecting canna lily seeds. For example, variety, size and bloom color. Different varieties offer unique flower shapes, colors, and heights. So choose based on your garden’s aesthetic needs.
If you prefer vibrant reds, opt for varieties like The President. For mixed or multi-colored flowers, Tropicana is a popular choice. Pay attention to the plant size. Some canna lilies will grow up to 8 feet tall. Others remain compact, which may be better suited for container gardening.
Local nurseries and garden centers often have canna lily seeds. Ensure the vendor is reliable with good reviews when buying online. For example, Burpee and Park Seed. This ensures high germination rates and quality plants.
Canna lily seeds have hard outer coats, which can delay germination. Soak the seeds in water to test seed viability. Viable seeds will sink and non-viable ones may float. Scarifying the seed coat can also speed up germination.
The best time is spring and early summer. Start seeds indoors 8-10 weeks before the last frost.
Scarify the seeds before soaking for better results. Gently filing or nicking the seed coat with sandpaper. Soak the seeds in warm water for 24-48 hours. This speeds up germination.
Plant the seeds 1/4 to 1/2 inch deep. Space them 2 inches apart when growing canna lilies from seed. This gives them room to grow. You should plant one seed per small pot if you're using containers.
The ideal germination temperature is 70-80°F. Placing the plastic seed tray in a warm area. Seedling heat mat can maintain a consistent temperature. Cover the seed trays with a humidity dome. They can create a greenhouse effect. This helps retain moisture and warmth.
Water once or twice a week when growing canna from seeds. But it may vary depending on climate and soil drainage. Underwatering leads to wilted and drooping leaves. Overwatering can cause yellowing leaves and soft. The mushy stems are due to root rot.
Canna lilies are heavy feeders. So providing them with the right nutrients. Start feeding seedlings with a diluted and balanced fertilizer. Switch to a slow release fertilizer after transplanting. Apply it every 4-6 weeks. This will support flowering and root development.
Insecticidal soap and neem oil can control aphids. Use organic barriers around the plants. For example, crushed eggshells and copper tape. These can deter snails and slugs. Manual removal may be necessary in severe infestations.
Fungal diseases are common in overly wet conditions. For example, leaf spot and root rot. Ensure proper spacing between plants for good air circulation. Avoid watering the leaves can reduce humidity around the plant.
Remove affected foliage immediately if you notice yellowing leaves or black spots. For root rot, reduce watering and improve drainage. This will prevent further damage.
Canna lily seedlings are ready for transplanting when they reach about 4-6 inches tall. They will have at least two or three true leaves. These true leaves are a sign that the seedlings are strong enough to handle outdoor conditions.
Another key indicator is the weather. Make sure the daytime temperatures stay above 60°F.
Handle the seedlings carefully when transplanting. Avoid damaging their delicate roots. Loosen the soil around the seedling in the tray or pot. Gently lift it by the leaves or root ball.
Prepare your garden bed or container. Loosen the soil 8-12 inches deep. Space the plants 18-24 inches apart. Because canna lilies can spread as they mature.
Harden the seedlings off before moving them outdoors permanently. Gradually exposing them to outdoor conditions. Start by placing them outside for a few hours a day. Gradually increasing sunlight exposure to 1-2 weeks. This process strengthens the seedlings and reduces transplant shock.
Choose pots 12-18 inches in diameter with good drainage holes. This also protects them from extreme weather. You can better control soil quality, moisture levels and temperature. Containers are especially useful in cold climates. You can easily move the plants indoors during the winter months.
Loosen the soil 12 inches deep. Amending it with organic matter. This improves drainage and provides nutrients. Before planting, ensure the area receives 6 hours a day. Space the plants 18-24 inches apart. This allows for proper air circulation and growth. These lilies can spread over time.
Your canna lilies will develop seed pods after flower. Wait until the pods begin to crack open naturally. Gently remove the pods from the plant. Carefully extract the seeds.
Canna lily seeds are round and hard. They have dark brown to black in color. Air dries the seeds for a few days after collecting them. Remove any excess moisture helps prevent mold during storage.
Place the seeds in a small container. Store them in a location with consistent temperatures. For example, a refrigerator. Avoid exposure to humidity. This can cause the seeds to deteriorate. Canna lily seeds can remain viable for several years with proper store.
