About Grape hyacinth
Grape hyacinth is neither a grape nor a hyacinth, though it is a close relative of the latter — the name comes from the tight cluster of small rounded flowers, which does resemble a miniature bunch of grapes. It naturalises very readily and can become a persistent colonist in lawns and borders, spreading both by seed and by producing offsets around the parent bulb. The leaves commonly appear in autumn, months before the flowers, and look untidy through winter, which regularly worries gardeners who assume something has gone wrong.
Growing notes
