The development sits almost exactly on the Meridian line and the garden designers Gillespies (who also landscaped the Skygarden on top of the Walkie Talkie, 20 Fenchurch St) took this as their inspiration, dividing the area into two geographic zones. Plants from the Western hemisphere such as ferns and Sweet Gum are on that side of the Meridian line, with Asian plants such as bamboos, magnolias and maples on the other. While the garden is mostly covered with a transparent roof, the central area is open to the sky, allowing in fresh air and pollinating insects. Paths wind through the planting with benches where you can relax and enjoy the surroundings. For the curious, descriptive plaques give details about the history of the area and the planting. Admission is free, and unlike the Skygarden, you can go there without booking in advance.
While work continues on the station in the basement, in other parts of the development shops, restaurants and a cinema have begun welcoming customers. The roof garden will also be playing host to theatre performances and family entertainment. See http://www.wharf.co.uk/whats-on/whats-on-news/events-coming-up-roof-garden-9234815
Once complete the 85-mile Crossrail line will stretch from Shenfield in Essex to Heathrow and Reading. Until then an easy way to reach Crossrail Place is the short walk north from the Jubilee line's Canary Wharf station.
