How are the heights measured?

All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.

What is a gallon container?

Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.

How does the delivery process work?

All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!

Why are some states excluded from shipping?

The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.

About Me


You will definitely make yourself happy, big-time, when you plant the Big Time Happy Daylily. Get ready for one of the earliest blooming varieties, and one that does it not once, but twice, coming back in late summer and into fall with a complete second blooming – wow! This fabulous plant has gorgeous 4-inch flowers with broad, flat petals that have fluted edges. They are colored a delicious light lemon yellow, darkening to a rich yellow-green in the throat. The blooms are special in staying fresh and open for 16 hours, so they will be gorgeous when you step out in the morning, and just as gorgeous when evening comes – which is terrific, because these light colors look so fabulous in the soft light of the evening, and really glow. Standing just 18 inches tall in bloom, it’s perfect for the front of beds, in smaller spaces and for growing in pots and planter boxes.

  • Soft lemon-yellow with yellow-green throat
  • Full flowers, 4-inches across with broad petals
  • Open in the morning and still great in the evening
  • Very early blooming, and blooms again in late summer
  • Compact size ideal for edging and pots

Grow your Big Time Happy Daylily in full sun, it’s the secret to reblooming. It grows well in cold zones, but also in hot and humid ones. Any well-drained soil is suitable, and richer ones are best. So mix in organic material when planting for maximum blooming. Established plants are quite drought resistant, so it grows well in drier soils and on slopes. Free of pests and diseases, just cut out the flower stems as they finish producing new buds, and cut everything to a couple of inches tall in late fall. Reliably perennial – it will be back next spring.

It’s hard to imagine summer in the garden without daylilies – which have come a long, long way since those tall orange ones in grandma’s garden. Today we have a profusion of varieties in colors from all across the spectrum, in different heights, and all with big, flamboyant flowers in profusion. Daylily season doesn’t have to stop in mid-summer, though, because today we also have access to an ever-growing range of reblooming varieties that do their thing and then come bouncing back to do it all again in late summer and early fall. You can have daylilies in bloom for months, not just weeks – and that must make all gardeners happy, big-time. Speaking of which, if you are looking for those months of bloom, look no further than the Big Time Happy Daylily. An abundance of lemon-yellow blossoms awaits, big, fluted blossoms on compact stems, in summer and in early fall. You will also be happy with the 16 hours this variety stays in bloom, so they open in the morning, and are still fresh and radiant well into the night – great for summer evenings outdoors.

Growing Big Time Happy Daylily

Size and Appearance

The Big Time Happy Daylily is a vigorous perennial plant that produces each spring a cluster of long, narrow leaves that are light to mid-green in color. They rise up and arch over in an attractive way, to stand about 12 inches tall, filling spaces and covering the ground. It blooms very early, just as summer is starting, and ahead of many other daylily varieties. The buds grow on a sturdy green stem, standing around 18 inches tall, and plants produce many stems, all carrying many buds. The sweetly-fragrant 4-inch flowers open flat and have the broad petals and fluted edges we see in all the best modern varieties. The color is a marvelous fresh, light, pure lemon-yellow, darkening in the throat, with touches of green at the base – a truly lovely blossom that is a full 4-inches across. Like all daylilies, this is an ‘extended bloom habit’ variety – the flowers open in the early morning, so they are up and great when you first step outdoors, and they stay open for 16 hours, so they are still great in the evening, not floppy and sad like older varieties. Perfect if you go to work in the morning and enjoy your garden mainly in the evening.

Once that early blooming is over, the plant takes a brief rest, and then by late summer and into the early days of fall, new flower stems grow up, and a whole second cycle of blooming brings glorious color back into your garden – double the pleasure we normally get from a daylily.

Using Big Time Happy Daylily in Your Garden

The shorter height of the Big Time Happy Daylily, just 18 inches tall in bloom, makes it perfect for edging beds or creating groups among other low-growing perennials. The color blends with just about everything except for hot pinks and purple-reds, and it looks ravishing growing with catmint, for example. Plant it on slopes, daylilies have tough roots that hold the soil and prevent erosion. For mass planting space 15 to 18 inches apart to produce a solid cover. Grow it too in containers and planters, which can be left outdoors all winter from zone 5 or 6.


Daylilies are very cold-resistant, and thrive in zones 3 and 4. Yet they grow well in warmer areas too, all the way into zone 9.

Sun Exposure and Soil Conditions

The Big Time Happy Daylily will perform at its best in full sun – this is especially important with reblooming plants, to maximize the chances it will rebloom. Grow it in any ordinary garden soil that is well-drained – richer soils are fine, and give the best results, but the great thing about these plants is how tolerant they are of poor conditions, growing well in low-grade soils, and tolerating drought conditions and heat amazingly well.

Maintenance and Pruning

Deer don’t bother daylilies, and problems with pests or diseases are rare. Remove the flower stems low down once the last bud has bloomed. This daylily doesn’t produce any winter foliage, so simply cut it back to an inch or two in late fall and you are done for the year.

History and Origin of Big Time Happy Daylily

Daylilies, or Hemerocallis, are a small group of plants, just 16 species, growing in China, Japan, and Korea. The earliest species grown in America was Hemerocallis fulva, the orange daylily, seen today in ditches and abandoned gardens in many areas. In the second half of last century there was an explosion of interest in these plants, mainly fueled by amateur enthusiasts, who created thousands of varieties. Only a few are distinctive enough to find their way into most gardens. Reblooming varieties are a more recent trend, starting around 1975. The variety called ‘Big Time Happy’ was developed by Dr. Darrel Apps and Robert Blew, from Bridgeton, New Jersey and released in 1993. It is a seedling of a cross between another rebloomer, ‘Happy Returns’, and a fragrant yellow plant called ‘Canary Late’.
