They may not be finished yet but Amazon certainly has a huge 'sphere of influence' on Seattle already.

The electric commerce mega-corporation unveiled three giant new steel-framed, glass-enclosed domes called, 'The Spheres,' and did the ceremonial first planting of the 400-plus species of plants that will eventually be housed there.

But there won't just be plants in the structures at Sixth Avenue and Lenora Street in Seattle, Washington.

The three spheres - the tallest of which is 90ft tall and 130ft in diameter - are part of a $4billion effort by Amazon to build a campus in Seattle, Washington

During the day, the temperatures of the spheres will be 72F with 60 per cent humidity and will be able to house more than 800 staff and personnel at the Sixth Avenue and Lenora Street location

More than 400 different species of plants will live in the domes and come from the company's Woodinville greenhouse

According to a press release given to media at the inaugural planting event, the domes are a space 'where Amazon employees can think and work differently.

'They are the result of innovative thinking about the character of the workplace and an extended conversation about what is typically missing from urban offices - a direct link to nature.'

Amazon also announced that it will donate $10,000 for improvements to schools' greenhouse and environmental education programs.

The interconnected domes are supposed to offer a chance for Amazon employees to work and create in an environment that more resembles the world than an office

All the plants are being cared for by an in-house horticulture team, led by botanist Ron Gagliardo (left joined by Seattle City Council member Sally Bagshaw, King County Executive Dow Constantine, Downtown Seattle Association President and CEO Jon Scholes and Amazon Director of Global Real Estate and Facilities John Schoettler)

In an interview, Gagliardo explained how planting the fern represented a big step after three years of hard work for his team that now consists of four people. 'Now we're there,' he said

Only select personnel and construction workers are allowed in the domes at this time

While an 11ft Australian tree fern raised in the company's Woodinville greenhouse was being planted at the event, John Schoettler, the head of Amazon's real-estate operations said: 'Today (Thursday) the Spheres truly come to life.

'I also call him 'The Lorax,' Schoettler said according to the Seattle Times, referring to the Dr. Seuss character who speaks for the trees.

In an interview, Gagliardo explained how planting the fern represented a big step after three years of hard work for his team that now consists of four people.

'Now we're there,' he said.

'When we got it, it was this big,' he said while holding his index finger and his thumb a few inches apart to show how small it was.

The five story structure will not have any official office or conference space and is slated to open in 2018.

Amazon has set up an Instagram account solely for the spheres so fans can follow the progress.
