The flowers of Hyacinthus come in a range of colors, including pink, purple, white, and blue. They are commonly used in gardens and as cut flowers, as their sweet fragrance and striking appearance make them popular for both ornamental and decorative purposes. It is important to note that the bulbs of Hyacinthus plants contain toxic compounds, so they should not be ingested.
