Crevice Garden

The Crevice Garden in Winter

The Crevice Garden, located at the corner of Shea and Holt drives,  was expanded in 2023. The Master Gardener Intern Class of 2023 extended the garden to the west end of the planetarium on Holt Drive.

From a distance, the garden appears to be asleep in December, waiting patiently for Spring to come. However, if you take a closer look, you will see a few cold-hardy plants thriving.


Have a seat on the bench in the west side of the garden and you will find Stonecrop, Candytuft, Garden Pinks and Ice Plant nestled between the crevices. These plants have evergreen leaves in winter and showy foliage in spring.


Stonecrop Sedum rupestre ‘Angelina’ is a succulent with evergreen leaves. When the weather gets cold, you may see its leaves turn a red orange in color. It prefers a sunny location but will do fine in light shade. Stonecrop is used as a ground cover, in rock gardens and in hanging baskets.

candy tuft1

Candytuft Iberis sempervirens ‘Alexander’s Whites’ is a low growing, spreading, evergreen ground cover. In the late Spring, this plant will be covered in clusters of four-petaled flowers that will last into summer, attracting various pollinators. It does well in sunny to part shady areas but will have more flowers in a sunnier spot.

garden pinks1

Garden Pinks Dianthus ‘Georgia Peach Pie’ is an evergreen perennial which flowers in late Spring, Summer and Fall. It does best in full sun. Dianthus is a good choice for borders, edging and rock gardens. It attracts bees and butterflies with its fragrant blossoms.


Ice Plant Delosperma ‘Fire Spinner’ is an ornamental perennial that does well with drought conditions. Evergreen in warm winter areas, it produces abundant blossoms from Summer through Fall. You can see a blossom in the photo above, taken in December!


Enter from the gravel path on Shea Street and you will find two additional winter hardy perennials around the old Oak tree.


St. John’s Wort Hypericum calycinum is a broadleaf evergreen shrub/groundcover. This plant tolerates growing under the heavy shade of large trees. In the Summer, it will present showy 3-inch yellow flowers attracting butterflies. It is resistant to drought and does well in rock gardens.


Cast Iron Plant Aspidistra is a shade tolerant perennial that does well in shady woodland areas. This plant is low maintenance. They got the name Cast Iron from their ability to tolerate poor soil and neglect. They can also do well as house plants.
