About This Exercise caution and use your best judgment before ordering during unusually hot or cold weather (below 32 degrees F, or in excess of 95F for shipping purposes), as these extremes may leave your plant vulnerable to damage. The optimal time for planting for most of our material is in mid to late spring, past the danger of hard frost. Please refer to our preferred shipping and planting guide for your area below. Medium height and mid-season blooming in a large selection of colors, make these tulips one of the most popular varieties. They have a strong stem which holds up well under windy conditions. Their height makes them an excellent choice for indoor forcing as well as cut flowers. Plant bulbs from October to December; Tulip bulbs can actually be planted up until Christmas and still flower perfectly well in the following spring because they only need a short season of growth. The rainbow of colors in this mixture will add the perfect touch to your garden this spring!
