ornamental onion

Ornamental onion (Allium hollandicum (incl. hybrids)) is an attractive flowering plant that provides tall mounds of blooms from summer to fall. It thrives best in full sun, so make sure to plant it in an area that gets plenty of direct sunlight. For ideal growth, water the plant every 2 to 4 days or about 1 inch of water per week. This can be done through either supplementing rain, sprinklers, soaker hoses, or hand-watering depending on your preference. Avoid overwatering, as this can cause root problems or make the plants too soggy and prone to disease. Be sure to check the soil before watering and if it’s already wet, hold off until it dries out a bit.

Ornamental onion is a flowering plant species that requires an ample amount of sunlight to thrive. When grown outdoors in temperate climates, these plants should be placed in locations with full sun (6 or more hours of direct sunlight daily). In more tropical climates, partial sun (4 to 6 hours of direct sunlight and shade the remainder of the day) is required. If grown indoors, the plant should be placed in an area near a south- or west-facing window. If possible, relocate the plant outside for a few hours each day, allowing it to soak up the direct sun. Additionally, the plant should be rotated periodically, so each side can enjoy equal levels of sunlight.

For ornamental onion, or Allium hollandicum (incl. hybrids), pruning should be done lightly in early spring. Remove dried flower scapes and small clumps of foliage that have started to die off. Prune back any foliage that is taller than the mid-section of the plant for a neat and tidy look. You may also need to snip off any foliage that is blocking out other nearby plants. This species is best if the pruning is kept to a minimum as it encourages a more bushy and mounded form.
