More Information

Description The compact Tuff Stuff Ah-Ha® Hydrangea (Hydrangea serrata) is packed full of flower power. This mountain hydrangea blooms in early summer and just doesn't know when to quit! You can expect massive, dinner plate size blooms of waterlily-like florets. Colors range from a soft pink to a light blue depending on the soil conditions. It's a prolific rebloomer, so you can enjoy a constant supply of flowers all summer long. Tuff Stuff Ah-Ha lives up to the name! Hydrangeas can lose buds during harsh winters, but this hydrangea won't fail. Its buds are cold tolerant and perfect for growing down to zone 5. Try planting it in flower gardens, cottage gardens, or patio containers for an impressive floral display. Details Botanical name: Hydrangea serrata 'SMNHSDD'
Patent #: USPP 29832

Height x width: 2 - 3' tall and wide
Flower color: Blue or pink
Foliage color: Green
Season of interest: Summer - fall

Features: Space savers, Proven Winners, heat tolerant, container plants, best sellers, best for beginners

How To Grow Soil: Average, medium moisture, well-draining soils. Mulch to conserve moisture and buffer soil temperatures.
Light: Most varieties tolerate full sun in the North, but benefit from afternoon shade. They tolerate full sun only if grown with consistent moisture. In the South, plants require afternoon shade. Intolerant of drought, with foliage tending to decline considerably in dry conditions
Water : Water to keep soil moist, but not wet.
Spacing: 2-3 feet
Fertilizing: Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15).
Winterizing: Remove any fallen foliage. The roots are shallow, so apply an extra 2-3" layer of mulch for insulation before winter.
Maintenance & pruning:Bloom on old wood, which means they have their flower buds for the following season all through winter, so they should not be cut back. Avoid pruning your mountain hydrangea except for dead wood in the spring.

Appears to be thriving; very hardy.

Also purchased 3 types of rose bushes
The Rose bushes don’t appear to be thriving so much; however I will give it more time .

I PLANTED THESE IN A POT ON SOUTHSIDE OF MY HOUSE AND LOOKS LIKE THEY CAN NOT HANDLE HOT SUN. IT WAS 87 DEGREES TODAY AND IT PARCHED LEAVES. I MAY TAKE OUT ON CONTAINER AND PUT IN SEPARATE POT UNTIL QT SIZE GETS BIGGER. DON'T LOOK LIKE THEY ARE GOIN TO MAKE IT.

Love them, very healthy, already thriving despite fall planting. I know they will do great things come spring and summer and I can't wait! As usual, thanks to Great Garden Plants, my reliable "go to" for purchases.

Beautiful, delicate blossoms

I planted this in fall 2021 and is frequently the case the hydrangea didn't do too much its first year. However you can see now in the second year I have tons of beautiful blossoms!
