OPUNTIA
Yes, you can plant other flowers around tulips when their leaves are still green. Be careful not to dig into the tulip bulb when planting the new flowers. When tulip leaves are yellow and brown and drying, you can give them a small tug and they'll come free from the bulb. Don't remove them while still green - they're making food for the bulb to store for next year's blooms.
