Solidago gigantea aka Tall Goldenrod
Taxonomy
Solidago gigantea, also known as tall goldenrod or giant goldenrod, is a North American plant species in the family Asteraceae. It is a rhizomatous, clump-forming perennial with upright, hairless stems that can reach up to 2 meters in height. The plant has lance-shaped leaves with toothed edges. From late summer into early autumn, it produces pyramidal panicles of flowerheads that can grow up to 30 centimeters long. These flowerheads consist of densely-clustered, small golden-yellow flowers. Solidago gigantea is the state flower of Nebraska and is also commonly found in Kentucky, where it holds the title of state flower. The central stem of this perennial wildflower is light green or pale purple, glabrous, and sometimes glaucous. It is largely unbranched, except at the apex where the flowering stalks occur. The individual branches of the panicle are light green, slightly to moderately pubescent, and recurved. Overall, Solidago gigantea is a tall and striking wildflower that adds beauty to its natural habitats.

Difficulty
If you're looking for a plant that offers a moderate level of challenge, Tall Goldenrod is a great choice to test your gardening skills.
Water
Tall Goldenrod should be watered regularly, allowing the soil to dry out between waterings.
Soil
Tall Goldenrod loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Tall Goldenrod prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Toxicity
Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.
Fertilizer
The Tall Goldenrod should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.
