Dicksonian Tree Fern in Cambridge - How Early is This?

I planted this beautiful Tree Fern is a small, really sheltered garden in central Cambridge last summer along with other Tropical plants including Gingers, Cannas and Bananas. This was taken on 6yh September 2023. It was packed with straw and fleece in the crown for the winter,

I went back today, 18th April 2024 and was amazed to see a mass of new fronds starting to appear so I removed all of last year's giant fronds to let these new ones come through. This is so early and you can see how much the plant has grown since last May!

Top down view showing all the new fronds coming through. I counted 17 new ibis. What a success story. t will be putting it's roots down properly now too and will be watered well throughout the summer along the base and also up and down the trunk.
