Daylilies are a garden favorite thanks to their vibrant colors, hardy nature, and long flowering season. But some gardeners have concerns about daylilies spreading uncontrollably on their own. In this article, we’ll explore the ways daylilies propagate and multiply, and provide tips for managing their growth.

Understanding Daylily Growth Habits

Daylilies, also known by their botanical name Hemerocallis, are herbaceous perennial plants They grow from crowns with fibrous roots and feature linear, arching leaves Daylilies produce colorful trumpet-shaped flowers on leafless stalks that emerge from the center of the plant.

A key fact about daylilies is that they are clump-forming plants. Each mature plant grows as a compact clump that expands gradually over time. They do not possess aggressive spreading habits like some perennial plants. However daylilies have developed a few mechanisms that allow them to multiply and expand their reach in the garden.

Do Daylilies Spread on Their Own?

Daylilies are adept at propagation through both sexual and asexual reproduction. This allows them to produce new plants without human assistance under the right conditions. Let’s look at the ways daylilies can spread naturally:

  • Seed Dispersal – Daylilies produce seed pods after flowering. While not prolific seed producers, winds and rain can disperse seeds to colonize new areas nearby.

  • Rhizome Growth – Daylilies expand via underground stems called rhizomes. New shoots and roots sprout from these rhizomes, multiplying the plant.

  • Stoloniferous Growth – Some daylilies produce above-ground stems called stolons. These stems allow the plant to expand horizontally and root at nodes.

  • Division – As clumps expand, daylilies may divide internally, splitting the parent plant into two or more new, independent plants.

Through these mechanisms, daylilies can definitely spread and multiply on their own without human intervention. However, most cultivars are relatively slow growing and spread is often manageable when properly maintained.

Tips to Control Daylily Spread

If you want to curtail daylily spread in your garden, here are some useful tips:

  • Remove spent blooms to prevent seed production.

  • Divide congested clumps every 3-5 years to control size and flowering.

  • Cut back stolons and rhizomes escaping beyond the desired area.

  • Install physical barriers like metal garden edging to contain growth.

  • Grow in containers above ground to restrict root expansion.

  • Select slow-growing, less aggressive cultivars suited for your environment.

  • Remove and relocate excess new plants as needed.

  • Monitor and quickly eliminate any unwanted seedlings.

Are Daylilies Considered Invasive?

While daylilies possess an ability to self-propagate, they are not categorized as invasive plants in most areas. True invasive plants damage ecosystems by displacing native species. Well-behaved daylilies coexist with other garden plants without causing harm when properly managed.

However, a few daylily species like Hemerocallis fulva have exhibited more aggressive tendencies. These require vigilance to prevent overspreading. Always research the growth habits of any daylily variety you plan to introduce.

Achieving Balance with Prolific Daylilies

Daylilies are prized in gardens for their vibrant, diverse colors and hardy nature. While they can certainly spread unaided via seeds, rhizomes and stolons, their growth tends to be gradual and non-aggressive. With smart planting choices and proper maintenance, prolific spreading can be prevented. Divide congested clumps regularly, remove unwanted growth, and utilize barriers when needed. Daylilies and other garden plants can thrive together in harmony with a little effort. Allow their cheery flowers to multiply and brighten your landscape without fear.

FAQ

How long does it take for daylilies to spread?

Container-grown or bareroot daylilies can be planted in spring or no later than 6 weeks before the first frost in autumn. In mild climates, they can be planted in summer. They’ll take about a year to establish themselves and then will spread quickly, forming dense clumps.

What happens if you don’t divide daylilies?

Daylily division should be tackled every three to five years for optimum health. If you never divide them, the plants will not grow as vigorously, and you will see fewer and smaller flowers each year. Newer varieties of daylily grow more slowly. You can wait longer between divisions for these.

Do daylilies reseed themselves?

Most daylilies do not self-sow; you need to divide daylilies to create new plants (see how below).

How fast do daylilies spread?

No plant enjoys drowning. One very large determining factor of how fast daylilies spread is how close you plant them to each other. If you plant your daylilies between two and four feet apart from each other, it can take two to three years for them to spread out and fill in the empty area.

Are daylilies easy to grow?

Daylilies are popular flowering plants that are widely grown in gardens and landscapes for their vibrant, showy blooms. They’re also incredibly easy to grow and propagate, making them a great choice for both experienced gardeners and beginners.

How long does it take for daylilies to grow out?

If you plant your daylilies between two and four feet apart from each other, it can take two to three years for them to spread out and fill in the empty area. However, if you plant them with about a foot between each one, it can take only about a year for them to grow out.

How to propagate daylilies?

Before you start propagating your daylilies, make sure you have all necessary tools on hand: Step-by-step guide on how to propagate Daylillies 1. Dig up the entire clump: Start by using a spade or digging fork to carefully dig up the entire clump of daylily plants from their current location.
