Lemon Lime Floss Flower

Lemon Lime Floss Flower (Ageratum houstonianum 'Lemon Lime')

Lemon Lime Floss Flower brings a fresh chartreuse foliage note to summer plantings, making surrounding colors look brighter and more intentional. Its soft, fuzzy flower clusters add a gentle lavender accent that keeps going from late spring into fall in many climates. The compact, mounding habit is easy to tuck into borders and containers, and it fills space without feeling heavy. If you want steady color with foliage that does more than just sit there, this ageratum delivers.

Distinctive Features

This variety stands out for its lime-green to chartreuse foliage paired with fluffy lavender flower clusters that sit above the leaves for a clean, layered look. Bloom is long and consistent, especially in full sun with even moisture, and the flowers hold their color well through summer. The plant forms a tidy mound that stays useful as both a color plant and a foliage contrast element. It also attracts butterflies and other pollinators, adding movement to beds and pots.

Growing Conditions

• Sun: Full sun to partial shade, with best flowering in fuller sun and afternoon shade helpful in hotter regions.
• Soil: Moist, well-drained soil with moderate fertility, amended with organic matter for best performance.
• Water: Medium, keep evenly moist and avoid repeated drought stress for continuous bloom.
• USDA Zones: Typically grown as an annual, perennial in zones 10 to 11.
• Mature Size: About 12 to 16 inches tall and 10 to 14 inches wide.

Ideal Uses

• Focal Point: Mass it in a sunny bed or large pot so the chartreuse foliage and lavender bloom become a bright focal point through summer.
• Border Edging: Plant along the front of beds for a tidy mound that keeps color and foliage contrast consistent.
• Containers: Use in mixed planters to lighten darker palettes and keep a fresh, clean look all season.
• Color Pairing: Combine with purple, magenta, white, or deep green plants for high-contrast, designer-style combinations.
• Pollinator Plantings: Add to annual beds to support butterflies and beneficial insects during the long bloom window.

Low Maintenance Care

• Watering: Water regularly during establishment and during hot spells to prevent stress and keep blooms coming.
• Deadheading: Shear lightly or remove spent clusters as needed to refresh the mound and encourage continued flowering.
• Feeding: Feed lightly during active growth, especially in containers, to maintain steady bloom without making plants soft.
• Spacing: Provide airflow and avoid overcrowding to help reduce humidity-related issues.
• Season Timing: Plant after frost and keep growth steady with consistent moisture for the longest display.

Why Choose Lemon Lime Floss Flower?

• Tidy Habit: Compact, mounding growth fits neatly in borders and containers.
• Pollinator Appeal: Flowers attract butterflies and other beneficial visitors, adding movement to plantings.

If you want an annual that brings both color and foliage contrast in a clean, easy-to-use form, Lemon Lime Floss Flower is a smart choice. Give it sun, even moisture, and decent drainage, and it will stay full and productive through the heart of the season. It is especially effective when repeated, because the chartreuse foliage reads like a design thread that ties the whole planting together.
