Ageratum Monarch Magic – Butterfly Magnet

Once in a while, a new plant comes along that I fall in love with—for its ease of growing, beauty, and all-around usefulness. This time, it’s the annual Monarch Magic Ageratum, introduced by BallFloraPlant, a one-of-kind plant . Commonly known as Floss Flower, it gets its name from the fine, thread-like texture of its tiny, fluffy petals, which resemble embroidery floss.

The plant, scientifically known as Ageratum houstonianum, has flowers composed of numerous small florets,  typically found in shades of blue and lavender and sometimes purple, pink, and white. Blooming in dense clusters, the flowers look like flat topped pompoms.

I used to grow the old species of Floss Flower for many years, but eventually gave it up—it just wasn’t very exciting. It stayed short and stumpy, required constant deadheading, and by late summer always looked sad and disheveled. Then I discovered the taller, more graceful varieties like Ageratum ‘Blue Horizon’ and never looked back. I love how it weaves effortlessly through perennial borders and adds a soft, airy touch to floral arrangements.

A new improved introduction of the old Ageratum flower has been  introduced called Monarch Magic.  Growing just 6 to 12 inches tall and spreading 8 to 16 inches wide, this variety has a lovely cascading habit that’s perfect for edging borders or spilling from containers. And what a blooming machine! I never had to deadhead—not once. Once it started flowering, it didn’t stop. The name Monarch Magic is no exaggeration—the Monarchs truly flocked to it. On hot summer days, I could glance out my kitchen window and see Monarchs, along with a host of other pollinators, swooping in for a meal. The blooms must be rich in nectar and pollen to attract such a crowd.

The best part of Ageratum is its deer resistance. Having a bitter taste and rough texture, the plant containers a substance that can cause liver damage in animals, thus making it less appealing to both bunny and deer browsing. Combine Ageratum with Vinca, another colorful easily grown annual that deer avoid, and you can have a container that looks beautiful in a heavily deer browsed area.

I noticed at the nursery where  I purchased it that the labeling says it needs deadheading. So far, I haven’t had to do that and I have been growing it for almost 4 months. Maybe later in the season, it might become necessary, but right now, I am enjoying the low maintenance beauty that has a constant parade of Monarchs.

    1. It’s best to inquire with the specific garden center or nursery where you are purchasing plants to confirm their neonicotinoid use.
