I adore Tulips. Every day is a surprise watching them develop into fully open blooms that follow the sunlight. I personally love how the stems grow longer & the flowers flow out of a vase in every direction. If you prefer your Tulips to grow a little straighter one trick is to take a pin & carefully push it through the stem just below the flower. Refer to picture below. Remove the pin, remove any lower leaves & recut your stems before placing your Tulips in water.
