Tetraploid Daylilies
"Tetraploid" sounds like a science word, and it is, but it's simple. A tetraploid daylily ("tet" for short) has four sets of chromosomes instead of the usual two. For gardeners, that often shows up as bigger, thicker flowers with heavy substance, richer color, sturdier scapes and more dramatic ruffles and edges.
Thicker petals hold up better in heat, sun and rain, so blooms tend to look good longer through the day. Many of today's showiest ruffled, gold-edged and eyed daylilies are tetraploids. That doesn't mean diploids (the two-set kind) are second best. Diploids include many of the most graceful spiders, doubles and old favorites, and you'll find plenty of them in our shop too.
Ploidy matters most if you want to try crossing daylilies yourself, since tets cross with tets and diploids cross with diploids. For everyone else, it's a handy clue to the bold, full look you're shopping for. Every plant page lists ploidy along with bloom season, height, fragrance and foliage type.
Getting them home: Every plant here is grown at our nursery in Vale, North Carolina. Pick yours up free in a full 3-gallon grow bag, or have it shipped bare-root, with the shipping cost shown in your cart. Daylilies grow across most of the country. Check the foliage type on each page if your winters are very cold or very mild.

FAQ
What's the difference between tetraploid and diploid?
Tetraploids have four sets of chromosomes and diploids have two. Tets often have thicker, larger blooms and sturdier stems. Diploids are often more delicate and graceful.
Are tetraploids harder to grow?
No. They need the same easy care as any daylily: sun, drainage and water during dry spells.
Can I cross a tetraploid with a diploid?
Generally, no. If you hybridize, cross tets with tets and diploids with diploids.
