‘Gus Mehlquist’ Sprawling Sand Cherry

Prunus pumila var. depressa ‘Gus Mehlquist’

Accession Number
The alpha-numeric value assigned to a plant when it is added to the living collection as a way of identifying it.
Accession Date
The year the plant’s accession number was assigned.
Common Name
The non-scientific name for the plant.
Scientific Name
The scientific name describes the species of an organism. The first word is the plant's scientific genus and the second is the specific epithet. This two-word binomial is sometimes followed by other taxonomic descriptors, including subspecies (denoted by "ssp."), variety (denoted by "var."), form (denoted by "f." or "forma"), and cultivar (denoted by single quotation marks).
Plant Family
The family to which the plant belongs.
Propagation Material
The first part (material code) describes the material used to create the plant. The most common codes are "SD" (seed), "EX" (existing plant), "PT" (plant), "CT" (cutting), "SC" (scion), "SG" (seedling), and "GR" (graft). The second part describes the lineage the plant is derived from. The last part describes the year of propagation.
Collection Data
The first part indicates provenance (place or source of origin) using a letter code ("W" = wild, "G" = garden, "Z" = indirect wild, "U" = uncertain). The second part lists the plant source. For wild-collected material, the collector, collection number, and country are given.
Location
The location of the plant on the landscape.

‘Gus Mehlquist’ Sprawling Sand Cherry

This New England native sand cherry was collected by the Arnold Arboretum in New Hampshire. Its name honors University of Connecticut plant breeding and biology professor Dr. Gustav Mehlquist.

On May 4, 1990, Harvard University research scientist David Boufford and Robert Nicholson, then Arboretum assistant plant propagator, found an extremely low-growing sprawling sand cherry (Prunus pumila var. depressa) along the bank of the Connecticut River in Cheshire County, New Hampshire. Boufford and Nicholson recognized the stature of this short sand cherry as something special. A division was harvested on that spring day, transported to the Arboretum, and transplanted directly into the plant production facility landscape. The small division later flourished into a thriving groundcover in the landscape beds adjacent to the Dana Greenhouses.

Under Nicholson’s watchful eye, the plant kept its prostrate habit over the next several years. Nicholson introduced the exciting horticultural find as ‘Gus Mehlquist’ in 1993 through the New Plant Forum of the International Plant Propagator’s Society (IPPS) in conjunction with the Smith Botanic Garden, where he was employed at the time of release. The cultivar name ‘Gus Mehlquist’ honors the University of Connecticut plant breeding and biology professor Gustav Mehlquist (1906-1999). Like Nicholson, Mehlquist was also an active IPPS member and was a contemporary rhododendron hybridizer to boot. In fact, one his hybrids, Rhododendron smirnowii × degronianum ssp. yakushimanum can be viewed in its spring glory in Rhododendron Dell, near the intersection of Hemlock Hill and Valley Roads.

To ensure that the desirable diminutive habit is retained, ‘Gus Mehlquist’ can only be propagated vegetatively (for instance, by stem cuttings) not seed, which is typical of cultivated varieties. Replicates of ‘Gus Mehlquist’ were provided to the nursery industry as part of the Arboretum’s first formal plant introduction endeavor, the Plant Introduction, Promotion, and Distribution (PIPD) program. This initiative was started by former Putnam Fellow Kim Tripp in 1995 and was actively stewarded by the living collections department into the early 2000’s. ‘Gus Mehlquist’ was one of three 2002 releases, together with Chinese plum-yew (Cephalotaxus fortunei) and Korean weigela (Weigela subsessilis).

Sprawling sand cherry is native to eastern Canada south to the northeastern United States. It is a spreading, low-growing variety of sand cherry (Prunus pumila), which has a wider range and is found throughout the northern half of the United States and southern Canada. ‘Gus Mehlquist’ sprawling sand cherry is a rapid spreader, growing 3’ per year once established. It is entirely prostrate, forming a dense mat as it roots along its stems. It stands only 6-12 inches above the ground, compared the 9-foot-tall height that a sand cherry shrub can attain.

Flowers are dainty with five white petals, followed by  blue-black fruits in September. It has elliptic dark green foliage through the growing season, with fall color displaying brilliant crimson and maroon hues. New stem growth is a warm brown turning to gray in maturity, marked with white lenticels. ‘Gus Mehlquist’ sprawling sand cherry performs well in normal garden conditions, and displays bolder fall foliage when planted in full sun. It is extremely adaptable to both dry and wet sites.

About Our Collection

Fun Facts

  • The original 30-year-old plant is flourishing behind the Arboretum’s Dana Greenhouses. It was collected as a division from the wild.

  • ‘Gus Mehlquist’ only reaches a height of 12 inches, but grows several feet wide. It will also root along its stems, increasing its footprint.

  • Rabbit browsing during the winter has no effect – vigorous growth the following spring and summer recoup any feeding by rodents.
