| My best guess would be Stock (Matthiola incana). I find the fragrance of stock is similar to Dutch Hyacinths. And both are exceptionally wafty. They're very cheap too and only cost $2~3 for a six-pack at my local nurseries. They prefer the cooler seasons and when Summer comes, they usually bow down. |
