[2] Populations that have been described under the synonym Tulipa neustruevae have firmer bulb tunics, more glossy leaves, and brighter yellow flowers. [3]
How do I plant tulip bulbs? Find a spot in full sun, which is about 6 hours of direct sunlight per day. Then dig a hole that’s about two to three times the depth of the bulb’s height.
