Things are about to get blooming serious in the land of Bake Off because it's Botanical Week. The rough guideline to the theme – which may not be featured again after the BBC1 series moves to Channel 4 in 2017 – is that anything that grows, goes.

This means we can expect an influx of floral shirts parading around the tent of dreams (we're imagining Paul Hollywood in a Hawaiian and Mary Berry rocking a poppy-print blazer). Hollywood has killed the dream, however, and will grace this week's episode in an all-black ensemble – proving that he doesn't have a budding interest in spring florals.

Presenters Mel and Sue are giddier than ever as they get the remaining seven contestants on their marks to bake in search of finding a blossoming stand-out contender among the seven remaining contestants.

Tensions remain high as there are a fair few messy meringues, with one disappointed baker claiming their aesthetically-displeasing creation "looks horrendous." There are, however, a good number of showstoppers on tonight's programme.

Bake Off news

In the news, it has been reported today that 2015 Bake Off winner Nadiya Hussain has claimed she has had "no offers" from Channel 4 to join the show next year. When asked if she was approached by the television channel, she told BBC's Newsround a straight "no".

She added:"I love writing, cooking and baking. I'm enjoying what I'm doing and I don't want it to be taken away from me." The long-running series, which is produced by Love Productions, received another blow last week when its key ingredient, Mary Berry, stepped down as judge.

"My decision to stay with the BBC is out of loyalty to them, as they have nurtured me, and the show, that was a unique and brilliant format from day one," she said in a statement. "The Bake Off family –Paul, Mel and Sue have given me so much joy and laughter."

"I wish the programme, crew and future bakers every possible success and I am so very sad not to be a part of it. Farewell to soggy bottoms," she added.

The show's other judge, Paul Hollywood, has contrarily signed a deal with Channel 4 to join the new version of the Bake Off.

The Great British Bake Off airs on BBC1 at 8pm tonight.
