Egyptian Starclusters are semi-tropical shrubs grown as annuals that seem to be tailor-made for butterflies The nectar-rich flowers grow in clusters over a long blooming season in the vibrant red, pink, and purple shades that act as a butterfly beacon. Clusters of many shallow blooms provide an easy access for the butterfly proboscis, allowing the insects to dip into many flowers in a short period. Bees like them too, so consider adding this plant to a landscape space you want buzzing with activity.
Starcluster plants that receive at least three hours of direct sun will have the best blooms. They appreciate a mildly acidic soil pH, in the range of 6.0. Amending the soil with compost or leaf mold can increase the acidity of your soil if it’s on the alkaline side. They need regular irrigation to stay healthy; keep the soil moisture about the same as a wrung out sponge.They tolerate dry conditions. Avoid regular overhead watering to prevent unsightly brown spots on the foliage.
