Mammoth Bulk - De Vroomen CA

BULK-READY VARIETIES

  • Begonias: Heavy‑duty flowering begonias deliver lush, saturated colour in shades of pink, red, yellow, and white. Large tubers built for robust garden beds or container plantings—perfect for high-foot-traffic landscapes and seasonal displays.
  • Callas (Calla Lilies): Elegant and architectural, Calla lilies bring refined form with their glossy foliage and trumpet-shaped blossoms. These rhizomes perform beautifully in borders or premium cut flower programs, delivering garden refinement at scale.
  • Crinum (Crinum powellii & others): Towering stems crowned with lily-like blooms bring tropical flair to large planting schemes. Crinums are reliable, long-blooming, and ideal for creating focal points in urban parks or generous perennial borders.
  • Ornithogalum (Star of Bethlehem): Striking clusters of white star-shaped blooms with bold centers, Ornithogalum offers excellent structure and bold contrast in massed plantings—especially in full sun and well-drained soil.
