Lobelia General Information

Lobelia are perfect for the spot in your garden that just stays too wet for most plants. Spires of colorful hood-like flowers open from bottom to top. Will naturalize along ditches and streams. Butterflies like them too. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Lobelia Plant Care

Prefers fertile, evenly moist soil. Can be divided every 2-3 years in spring. Allow to self sow. Winter over with stems on. Can be pinched back before flowering to produce more compact plants. May benefit from light winter mulch north of zone 6.

Plantable Pots

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!

100% Guarantee

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!
