The leaves are the reason to plant The Rising Sun™. New growth comes in pumpkin-orange, then moves through gold and yellow before settling to lime green. Because the tree keeps pushing out new leaves all season, every branch carries the whole range at once: green near the trunk, orange at the tips. It's a cultivar of our native eastern redbud, and it won the Pennsylvania Horticultural Society Gold Medal in 2012.
In early spring, before any leaves appear, small pink-purple flowers line the bare branches the way they do on any redbud. Then the orange new growth takes over, and the color show runs from spring into fall.
At 10 to 12 feet tall and about 10 feet wide, it fits where a full-sized redbud won't: border gardens, flower beds, or a specimen spot in a smaller yard. We grow it at the nursery and have it in our own yard. Our favorite use is a group of three, underplanted with deep-green hostas, perennials, grasses, or ferns depending on the light. The leaves already carry plenty of color, so pair them with solid deep greens, purples, or pinks, along with dark mulch or hardscaping, rather than other variegated plants. If you want the same color on a bigger tree, look at Rise 'N Shine™.
It handles heat and drought well, and the foliage holds up in hot summers without burning. Give it full sun to part sun. It needs at least 6 hours of sunlight a day, because too much shade narrows the color range. More new growth means more color, so a slow-release fertilizer each spring pays off directly. We ship redbuds bare root and dormant. Plant as soon as yours arrives and follow our tree planting guide, which is also what qualifies your tree for our warranty. If you're in zone 5b or colder and ordering in fall, we can hold your tree in our cooler and ship it in early March.
Ray and Cindy Jackson of Jackson Nursery in Belvidere, Tennessee, found The Rising Sun™ as a chance seedling in 2006. They partnered with Greenleaf Nursery in 2010 to introduce it through the Garden Debut® program.

General care for any tree or shrub is easy, but like any living thing will require your attention. Please educate yourself and follow these simple rules.

Soil quality and how to plant the Rising Sun Redbud
The Rising Sun, like most redbud trees prefers consistently moist soil that is rich in organic matter, but can do well in a wide range of soils. Soil compaction will restrict growth and should be addressed by digging as large a hole as possible. We recommend a minimum of 3x3 ft. and digging at least 18 inches deep to break up the soil. Remove the grass, but retain as much of the original soil from the grass clumps as possible. A higher quality soil can be supplemented, but use no more than a 30% new to 70% original soil ratio. Too much new soil can cause water to pool in the hole, which will drown and kill the plant. With redbuds, mulching is extremely important (especially in the early years) as it suppresses grass and weeds, retains moisture, improves soil quality and reduces the chances of compaction from foot or mower traffic. For more specific details on how to plant see our guide.
When to fertilize the Rising Sun RedbudThe Rising Sun depends on new growth for it to maintain it's spectacular appearance, so fertilizer is recommended for optimal growth. A soil test is recommend for accurate fertilization, but a general NPK + micronutrients slow release fertilizer will cover the basis if a test is not performed. We recommend a 10-11 month slow release fertilizer be applied each year as a top dress in the mulch around the growing area. Apply this fertilizer prior to spring, so that the tree has access to nutrients in the spring and fall growing periods.
How and when to prune the Rising Sun RedbudPruning can be a challenge for new gardeners, so unless you are experienced, we recommend limiting pruning to a few branches each season. Pruning can be done during the winter months, but will rob you of the newest blooms. Pruning can also be done in late spring, after the blooms fade. Try to focus on branches that cross into the tree or create a steep V as these can create rubs, restrain growth on the central leader, and lead to breakage. Prune branches that are lower to the the ground to allow for space under the tree for mowing and and a more tree-like appearance. Most redbuds will grow shoots around the base of the tree, trim these back as low to the ground as possible each season. I've seen shoots grow almost to the size of a small tree within a few months, so get them as early as you can. When pruning take care to prune branches when they are as small as possible and take no more than 1/3 of the branches from a tree in one season.
