Ashikaga Flower Garden

Will I see certain kinds of Wisteria in full bloom if I go Ashikaga Flower Garden on April 13th? I noticed this year , cherry blossom is early. Will Wisteria be early too. In some website, I saw that blooming time is also from Mid April but some in end of April. But If not, what kind of flowers I will see?

We were in Ashikaga Flower Park on April 25 last year and wisteria was not in bloom.

Here are some of the Park archive photos last year during the end of April.

True that cherry blossom season is much earlier this year but even if wisteria will bloom earlier it is doubtful whether it would be as early as mid April. You can monitor the following webpage for the flower blooming situation in the Park. Tulips and cherry blossom are evident a couple of days ago.

Thank you very much. Appreciate you answer. I will follow the website you mentioned. It is so beautiful in the photos. I do not know where else to see Wisteria in Mid April. Even if we see it , it will not be full bloom like tunnel for sure then.
