Knautia macedonica 'Thunder & Lightning' (PP21,437)
Knautia are upright, clump-forming perennials. Avoid too moist (wet feet). This is an excellent choice for the front of the border. Compact size also makes it great for containers.
Can be divided every 3-4 years in spring. Avoid soil that is compacted or wet in winter. To ensure a supply of flowers, prune oldest stems to the ground to make room for the newer ones. Leave some spent blossoms, birds love the seeds.
Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
We offer a 100% guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
We use custom, earth-friendly packaging to make sure your order arrives in great condition, and we ship based on the best planting time for your growing zone (see the approximate dates below), unless otherwise indicated at checkout. If you wish, you can indicate a specific ship date during checkout.
