Allium 'Globemaster'
Overview
Ornamental onion (Allium 'Globemaster') is an amazing plant species to have in any garden. Its tall flower stems, with unique globe-shaped clusters of lavender-purple flowers, create an impressive show of color and texture in the garden. The strong aroma of the pollen deters deer and rabbits, making it a great choice for wildlife gardens. It's also very low maintenance and drought tolerant, only needing a light fertilization early in the growing season for optimal blooms. Ornamental onions are mainly perennial and will come back season after season.
Care Guide
Watering
Water your ornamental onion deeply, about every 5 to 7 days in the hotter months of the year, and allow the soil to dry out slightly between waterings. In cold months, they may need less water, about once every 10-14 days. When watering, make sure you fully saturate the ground around the plant with water. Don't just splash a little water against the stem or leaves. It's also important to monitor the soil's moisture level to ensure your ornamental onion is getting enough water. If the soil is too dry, the leaves may start to wilt.
Light
Ornamental onion (Allium 'Globemaster') plants prefer full sun, which means they need 6 to 8 hours of full sun per day. The best time of day for plants to get sunlight is in the morning or early afternoon. This allows the plants to benefit from the light of the day without the added heat of the sun. Ornamental onions should receive full sun for best growth and flowering.
Temperature
Hardiness zone 5–8.
Pruning
Ornamental onion (Allium 'Globemaster') should be pruned at the end of the winter season, or in early spring before the flowers begin to bloom. Pruning should be done in order to get rid of any dead, damaged, or diseased stems or foliage. To prune, use clean, sharp pruning shears and cut back the foliage and stems down to a few inches above the ground. Additionally, any dried flower heads should be removed once the blooming period finishes.
