Echium pininana aka Giant Viper's Bugloss

Taxonomy

Echium pininana, commonly known as the tree echium, pine echium, giant viper's-bugloss, or tower of jewels, is an endangered species of flowering plant in the borage family Boraginaceae that is endemic to the Canary Islands, where it is restricted to the island of La Palma. Despite its name, it is not closely related to pine or resembling it in any way. Echium pininana is a stunning biennial plant that forms a low rosette of silver, hairy, spear-like leaves in its first year, and sends up a huge spike loaded with small blue flowers in its second year. It has been awarded the Award of Garden Merit (AGM) by the Royal Horticultural Society, and is extremely attractive to bees for pollination. This species is something of an aggressive self-seeder, so it is best suited to mild, sheltered parts of the UK. Unfortunately, it is also invasive in Australia, South Africa, and the United States. As a houseplant, Echium pininana requires regular watering, long-lasting, direct light, and well-draining soil. It should not need additional fertilizers as long as it is repotted each time it doubles in size.

How to care for Giant Viper's Bugloss

Difficulty

Even if you don't have a green thumb, you can successfully care for Giant Viper's Bugloss due to its easy-going nature.

Water

Giant Viper's Bugloss should be watered regularly, allowing the soil to dry out between waterings.

Soil

Giant Viper's Bugloss 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

Giant Viper's Bugloss thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Tower Of Jewels.

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 Giant Viper's Bugloss 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.
