Prime-Ark® 45 Blackberry Bush

Availability: Out of stock

If you just love sweet, juicy blackberries, you'll want to include Prime Ark® 45 Blackberry Bush (Rubus 'APF-45') in your edible garden this year! Twice a year you'll enjoy glistening white blossoms and the pollinators that flock to these blooms. With their help, these self-pollinating flowers produce two crops of delectable glossy black berries!

You'll definitely get your blackberry fix with these delicious and healthy fruits! The first, heaviest crop comes in June on second-year Floricanes, then you'll usually see a second crop on new Primocanes later in the season, making this a wonderful and bountiful everbearing blackberry bush!

You might have a hard time gathering enough for a bowl, as you might find yourself eating them straight from the bush. These berries are known to ship well, so if you are able to control yourself, you'll be pleased with how long the berries last inside.

Planting and Application:

Regardless of how much space you have available, this is an excellent, erect-growing variety that produces berries that are succulent, firm and of good size! The flowering and fruiting displays twice a year, in conjunction with the gorgeous, toothy and textured green foliage, make these fantastic landscaping plants! Use them anywhere you would any other flowering shrub in the sun.

The thorns create a sturdy defensive barrier year-round, so use these and other fruiting shrubs as linear berry orchards that feed you, provide great privacy or block that messy neighbor, keep trespassers out, and give birds a place to nest and hide! Urban edible landscaping and food sustainability never worked so hard for you!

  • Sweet Firm, Good Sized Blackberry
  • Gorgeous White Blossoms
  • Lovely Green Textured Foliage
  • Early Ripening & Later Second Crop
  • Boon for Pollinators & Birds!

#ProPlantTips for Care:

Prime-Ark® 45 needs full sun to do its best flowering and fruiting, favoring the drying power of the morning sun. Plant in enriched, well-drained highly organic and slightly acidic soil and a thick layer of mulch on top to insulate and protect roots. Keep the soil moderately moist for best results! In late winter or early spring, prune out all the canes that fruited last year, cutting them to the ground.

  • Full Sun
  • Prune Everbearing Canes Late Winter/Early Spring
  • Slightly Acidic Organic Soil
  • Moist, Well-Drained Mulched Site
  • ~300 Chill Hours

Delicious flavor, improved disease resistance and sweet, big, firm blackberries. There's not much better than that! Order the versatile and hard-working Prime-Ark® 45 Blackberry Bush for yourself today from!
