Daylilies are beautiful and hardy perennials that can add a touch of elegance to any garden. While they only bloom for a single day, these plants produce an abundance of vibrant flowers over several weeks. Most daylilies found in UK gardens are hybrids, meaning that growing them from seeds won’t result in identical plants. However, if you’re interested in experimenting and creating unique hybrid daylilies for your garden, learning how to grow them from seed can be an exciting proposition. In this article, we’ll walk you through the process of growing daylilies from seed, giving you the opportunity to develop your own stunning varieties.
Collecting Seeds
To begin the process of creating new hybrid daylilies, you’ll need to cross-pollinate two parent plants with desirable characteristics. Master Horticulturist Peter Lickorish recommends using a cotton bud or even a pen to collect pollen from one flower and transfer it to the stigma of another flower. This can help control which daylily varieties you combine and allow you to create unique hybrids with specific traits. After cross-pollination, cover the flower with a sock or similar method to prevent further pollination. Keep in mind that some daylily varieties have twice the normal number of chromosomes, which can complicate breeding. Once the flowers fade, there’s a 50% chance that a seed pod will develop. If a seed pod does develop and ripen successfully, collect the black seeds in preparation for sowing.
Sowing the Seeds
Daylily seeds can be slow to germinate, so patience is key during this stage. In the UK, the best chance of success is to store the seeds in the fridge for about six weeks before sowing them. Sow the seeds 1.5-2cm deep into pots or seed trays filled with peat-free potting mix. If possible, use a greenhouse or other undercover area to maintain the ideal temperature. Keep the medium moist, and germination should occur within a couple of weeks if the temperature remains above 16°C. Once the seedlings are large enough to handle, transfer them to individual pots.
Hardening Off and Planting Out
To ensure the daylilies grow strong and healthy, overwinter them in the greenhouse during their first winter. This step helps them acclimate to the outdoors gradually. Once the danger of frost has passed in your area, harden off the seedlings and plant them in your garden. Choose a suitable spot and make sure to follow the recommended spacing guidelines for daylilies.
Waiting for New Daylilies to Flower
While the process of growing daylilies from seed is relatively straightforward, it requires patience. It typically takes 2-3 years for the new plants to reach maturity and produce flowers. During this time, you’ll eagerly anticipate the reveal of your unique hybrid creations. In the end, all your efforts will be rewarded when you finally witness the beauty of your new daylilies in full bloom.
So, if you’re ready to embark on a gardening adventure and create your very own hybrid daylilies, follow these steps and enjoy the anticipation of watching your garden transform into a colorful symphony of unique blooms.
