Anderson advised on Friday that the display will be at its best for the next ten days.
He said: "We have been busy over the early Easter holidays and our visitors have all been flocking to see the magnolias with cameras in hand. We have been fortunate this spring not to have had many frosts, which damage the magnolias, so this is a great year to see them."
Stars of the show include two magnolias very close to the visitor entrance – the sky piercing Magnolia veitchii and the large blooms of Magnolia Apollo.
"These magnolias definitely have the wow factor" said Anderson. "Their pink blooms set against a blue sky are one of the wonders of spring. Look out too for 'Black Tulip' near the Sundial Garden with its distinctive dark purple flowers. Elsewhere we have other magnolia walks in the Home Wood area of the Gardens, with Magnolia soulangeana 'Alexandrina' in full flower and the smaller flowers of Magnolia stellata 'Star Wars' putting on a wonderful display behind rows of camellias on the New Camellia Walk.
Exbury has over 150 different types of magnolia, many of them mature specimens, with blooms ranging from white and yellow to shades of pink and purple.
