Another flower of the day; white lace flowers

I saw a beautiful display of white lace flowers in May in Saitama Prefecture and fell in love. White lace flowers typically bloom in May in Japan, but for some reason they are the birth flower of October 4th. They are also the birth flower of March 15th and June 7th. You might still be able to find white lace flowers blooming in June, but it is unlikely that you will find any in bloom right now. But you might be able to pick some up in a florist. 

White lace flowers are so named because they resemble delicate white lace. They are said to represent a "pretty heart", "delicate love" and "gratitude" in the 'hanakotoba', aka language of flowers. I really don't know much more about white lace flowers unfortunately. I hope I can learn more over time. An Internet search revealed that they are native to the Mediterranean and thrive in vineyards and olive groves. 

According to Wikipedia, there scientific name is Orlaya grandiflora and they are a species of a flowering plant in the Apiaceae family. I find them so gracefully delicate and would love to grow some myself. Have you ever grown white lace flowers? Have you seen them in either a garden or florists here in Japan?
