Hollyhock rosea 'Polarstar'
Hollyhock are perhaps the definitive old-fashioned garden plant. Flowering from late spring through summer. From the Spotlight™ Series, this versatile Hollyhock is a multi-use plant that can be grown as a cut flower, used in large containers or planted in the landscape. Best selection for the coldest areas (zones 3 & 4), not for the gulf states.
Truly a perennial, will bloom the first year from seed. Allow to self sow to ensure future plants. May need staking. Rust (little orange dots on the leaves) can be a problem in high humidity and can be treated with a copper based fungicide. Cut plants back to 8" after blooming.
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!
