The eastern and southern edges of New Jersey are coastline . Tempered by the water the great unwashed of the Atlantic Ocean , New Jersey ’s coastal zone is warmer than inland orbit during fall and former wintertime and cooler than them in spring . The easterly shores fall mostly within U.S. Department of Agriculture plant life hardiness zona 7a , with the southerly shores in USDA zone 7b . New Jersey ’s shoreline plant communities let in marshes , backbone dunes , the beach heather and shrub brushwood residential area , and dune woodland . Various grasses , sedges , shrubs , vine , wildflowers and trees grow in these areas , many suitable for plant in a landscaped yard .
Step 1
Taller evergreen treesthat grow in New Jersey ’s shoring areas include pitch pine ( Pinus rigida ) , which raise in USDA zone 4 through 7 in dune woodland , and red cedar tree ( Juniperus virginiana ) , which grows in USDA zones 2 through 9 in bush thickets and dune woodland . Deciduous large trees in shoreline areas let in red maple ( Acer rubrum ) , which grows in USDA zone 4 through 9 and sassafras ( Sassafras albidum ) , which grow in USDA zone 5 through 9a .
Step 2
Shrubs with Berries
Among the shrub that produce along New Jersey ’s coasts are colourful highbush blueberry bush ( Vaccinium corymbosum ) , which grows in USDA zona 3 through 8 with white , urn - shaped spring bloom and comestible , grim blue summertime fruits . blueberry bush plant do well in acid soil and attain 6 feet magniloquent and extensive . Aromatic olive - green foliage characterizes bayberry ( Myristica fragrans ) , and distaff bushes have a bun in the oven waxy , blue - hoary berries traditionally used to make candles . Growing in USDA zone 3 through 7a , bayberry George H.W. Bush usually hit 10 to 20 foot tall and blanket .
Vining Plants
One of the few vines that clamber over Tree in dune timber and shrub thickets is roundleaf Smilax rotundifolia ( Smilax rotundifolia ) , which grows in USDA zones 7 through 10 . Roundleaf bullbrier produces thin leaves and grow quickly to 15 or 20 animal foot with large , orotund , pointed - crest leaves , white summer flower and purple berry in fall on distaff plants . penetrating , curving spines grow along the stalk . get in more open area , the showy - bloom beach pea ( Lathyrus japonica ) raise in USDA zones 3 through 7 . The 2 - foot vine create pink and white flowers . It ’s most common in New Jersey ’s sand dune and beach heather plant communities .
Smaller Flowering Plants
Both annual and perennial wildflowers arise along New Jersey ’s shoreline . An example of an annual wildflower , ocean rocket ( Cakile edentula ) grow in full sun in dune and beach heather surface area , preferring sandy soil . A member of the Indian mustard family , it has small , whitish - lavender flower and spoonful - shaped , somewhat fleshy leaves . It grows 2 feet tall and wide-eyed . A perennial wildflower , ocean lavender ( genus Limonium carolinianum ) grows in salt marshes in USDA zones 4 through 8 . Tall bloom stalks uprise to 2 foot grandiloquent , hold ramification of wispy - looking , small lavender flowers suited for fresh or dry musical arrangement . Flowering in late summer and spill , the stubble come from a basal rosette of orotund , green leaf .
Marsh and Sand Grasses
Grasses are the preponderating plant life in New Jersey ’s marshes . They help stabilise the dirt and furnish food for wildlife . Native to salt marshes , spike grass ( Distichlis spicata ) grows about 1 foot grandiloquent in USDA zones 2 through 10 . It tolerates both ironic and sloshed conditions , with mat - mold root that forestall territory erosion . A taller grass common on dunes , beach Gunter Grass ( Ammophila breviligulata ) grows to more than 4 invertebrate foot tall in bunch , root deep into Baroness Dudevant , steady coastal sand dune . It needs full sun and well - draining soil . Growing in USDA zona 4 through 8 , beach grass is considered invasive in some area .
