Amsonia 'Midway to Montana'

Overview

Blue Star (Amsonia 'Midway to Montana') is an amazing species of plant that makes a great addition to any garden. Native to the Midwest United States, the plant is an herbaceous perennial that produces dense, soft foliage while the eyes are drawn to its unmistakable deep blue star-shaped flowers. It thrives in full sun to partial shade making it a versatile species, and will re-bloom in mid-summer if withered blooms are trimmed back. This drought-tolerant, low-maintenance beauty works well in borders or cottage gardens, as well as makes for a great cut flower.

Care Guide

💧

Watering

Blue Star needs to be watered consistently, but only when the soil starts to dry out. Check the soil weekly after the plant is established and water until it just begins to come out of the bottom of the pot. During the growing season, water more often (every 3-4 days) because this species tends to perform better with regular waterings. During winter, reduce waterings to every 5-7 days.

☀️

Light

Blue star (Amsonia 'Midway to Montana') should be provided with at least 6 hours of direct sunlight each day for optimal growth. If possible, the plant should be kept in a sunny area with at least 8 hours of direct sunlight per day, but not more than 12 hours. Too much sun may result in scorched leaves and can impede growth.

🌡️

Temperature

Hardiness zone 4–9.

✂️

Pruning

Pruning should be kept to a minimum to retain the attractive mound shape. Pruning should only remove 1/3 of the plant each year cutting just above the node. It is important to remember that new growth may need to be trimmed back in late spring or early summer in order to maintain the desired shape.
