    Uses Notes: 

    Excellent for mixed borders or woodland gardens. Can also be used in wildlife gardens. Its small size makes it a good fit for narrow beds or smaller gardens. Also good as a foundation plant.

    Maintenance Notes: 

    Little care is needed for this plant. It may be pruned to shape in late winter/early spring. It holds its tight, dense shape so heavy pruning is rarely needed. If desired, apply a granular fertilizer formulated for woody plants in early spring.  Tolerates damp soils.

    Add some fragrance to your late summer garden! 

    This dwarf summersweet has very fragrant pure white flowers that attract butterflies in mid-summer. It has dark glossy foliage and holds its tight dense shape without pruning. The dark green foliage turns yellow in fall. An excellent native plant for the home landscape.

    • I had high hopes for this plant, but they were in the ground for just 1 night before the deer found them and decimated all 6 of them. They are now surrounded by an electric fence...we'll see what happens next year.

    • I bought Vanilla Spice along with Sugartina Crystalina variety - both were labelled as fragrant. Well, none of them have any fragrance. On top of it these are highly invasive. I have the suckers popping everywhere on my flower beds. they have thick root system, but pulling them is ok because they seem to be spreading not too deep. However, I am not a fan of this, because while the flowers are ok, there is no fragrance and invasive. I will have to remove from the ground and put them in a concrete container.

    • I planted three of these two years ago in a small clump where they get about 3 hours of direct mid-day sun. They bloomed for 5 weeks both summers. I've been especially impressed with the fall foliage -- a pleasant but not especially notable pale brownish/yellow with hints of pale green, but when planted beside a big-leaf rhododendron (English Roseum, in my case), the clethra seems to glow. I will definitely be planting more next year elsewhere in my garden.

    • I'm sorry to say I am disappointed with this shrub. I planted it last year. This year it did bloom mid-August. The blooms only lasted 2 or 3 days and then browned. Also I could not detect a scent. I was looking forward to a fragrant shrub.

    • I planted this clethra spring of 2018, quart-sized. It grew nearly triple its size but did not bloom that summer. This year, it has been a strong grower and is blooming with many beautiful fragrant long-lasting blooms. Very pleased!!!

    • Was delivered healthy and packaged very well. Out of all the shrubs I planted this one has the most new growth in the shortest time. I have only had it for a month or so but it is thriving in North Carolina.

    • Wondering how long before new growth, (leaves) begin on previous years plant?

    • This bush was given to me as a dead stick. It has been transplanted twice and is beautiful. Smells great and the deer never touch it.
