Did you know Tulips actually continue to grow after they are cut and they do not need cut flower food? ๐ฏ๐คญ They will grow about an extra inch after they have been cut. โฌ๏ธ They will also bend and twist to grow towards the light even when they are in a vase! If you keep them well watered and away from heat sources like radiators, they should last around seven days.
