Flower in Darts Hill Garden

Flower in Darts Hill Garden. Tulip?

 

Yes Tulip..Tulipa sp.

Is the centre blue?
It may be Tulipa hageri "Little Beauty."

Paghat's Garden: Tulipa hageri 'Little Beauty'

 

Probably, they were not open. Are tulip's leaves can be so narrow?

 

Yes, they can. Many Tulipa species do. I grow in my garden a 'Peppermint Stick' Tulipa clusiana, which has leaves even more narrow.

 

Thank you
