Or you may go to 花墟 to have 12 橙紅色鬱金香,襯<滿天星>或<毋忘我> , around $200 I think. Unlike roses, how many stews is not important for 鬱金香. No less than 10, no more than 15 should be the right size for a girl to carry home.
If 10 鬱金香, I think it would be better to go with 毋忘我 and mix them together. If 15 鬱金香, then may use 滿天星 just to surround the main flowers
