Description

(Tagetes erecta nana). This marigold carries one of the great flower-breeding stories of the last century. For 56 years, Burpee chased the dream of a true white marigold, even offering a $10,000 prize to the home gardener who could help make it happen. Thousands answered the call, and after 21 years of seed submissions, Alice Vonk of Sully, Iowa, won the prize in 1975—after Burpee had spent over five decades and $250,000 in testing. Kilimanjaro White French comes from that same long white-marigold quest, developed by Hem Zaden on a farm on Mount Kilimanjaro. The fluffy 3-inch creamy-white blooms look spectacular in bouquets and stand out in the garden like moonlight among the usual gold and bronze.

Growing Guide

When to Grow

Sow indoors 4-6 weeks before the last expected spring frost or direct sow once the danger of frost has passed. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds 1/4 inch deep in fertile, moist, well-draining soil. Maintain even moisture during germination. Provide bright light or full sun to promote strong, sturdy seedling growth.

How to Grow

Thin or transplant seedlings when they are 2–3 inches tall, leaving 10–12 inches between plants. Ensure full sun exposure for best flowering. Water at the base and feed with a balanced fertilizer monthly. Regular deadheading keeps the plants neat and blooming.

FAQ

Are Kilimanjaro White marigolds good for floral arrangements?

Yes, their creamy white blooms and strong stems make them a favorite in fresh floral designs. Harvest early in the day for maximum vase life and minimal wilting.

Do Kilimanjaro White marigolds need staking?

Generally, no. These are compact, dwarf African marigolds. However, in windy locations or with heavy blooms, a light stake may help prevent leaning or stem damage.

With consistent sun, moisture, and regular deadheading, they bloom continuously from summer to frost, offering elegant white blooms that contrast beautifully with vibrant garden colors.

What gardeners are saying

  • Big ruffled blooms: Huge chrysanthemum-like flowers on long stems for cutting.

  • Easy from seed: Germinates readily and shrugs off poor soil and heat.

  • Late but long: Slower to bloom than French types, then flowers to frost.

  • Tall, bushy plants: Three to four feet tall and bushy; often lean without staking.

  • Heads up: Blooms are cream to pale yellow, not pure white.
