I'm really curious to know how tall Nepeta 'Six Hills Giant' grows, especially when it's fully grown. Do you think it could reach 25 feet?
I'm pretty sure I know. This Nepeta 'Six Hills Giant' plant is about 2-3 feet (or about 60-90 cm) tall. The size is also influenced by the soil, fertilizer, and watering.🌿😊
This plant may reach a height of 60 cm, in my opinion.
This 'Six Hills Giant' Nepeta can grow to 36 inches!
From what I know, this plant can grow to about 2 feet, and the flower spikes can reach up to 3 feet!
