One of London's most surprising green spaces is about to shut its doors for a while. The Barbican Conservatory — the huge, jungle-like glasshouse hidden on top of the Brutalist arts centre in the City of London — is heading into a restoration, and before the work begins it's hosting a final-chance event where visitors can take home free plant cuttings. It's a rare opportunity to grab a living souvenir from a place most Londoners don't even know exists.

The conservatory is a genuinely odd gem. Tucked above the Barbican Centre's foyers, it's one of the largest glasshouses in the capital after Kew, home to more than 1,000 species of tropical plants and trees, koi carp gliding through ponds, and even resident terrapins. It opened back in the 1980s and has that unmistakable atmosphere of finding a rainforest in the middle of concrete towers — brutalism on the outside, humid greenery within.

Access has always been limited. Unlike a normal park, it doesn't open daily; the conservatory typically welcomes the public only on selected weekends and for ticketed events, so visits require a bit of planning at the best of times. With the closure for restoration now confirmed, those chances are about to become a lot scarcer for anyone who hasn't ticked it off yet.

That's where the cuttings event comes in. The idea is simple and rather lovely: rather than waste plants during the restoration works, the Barbican is letting visitors take cuttings home free of charge. You get a piece of the conservatory for your windowsill, and the venue gets a nice send-off while the much-needed renovation happens. Details of exact dates and how the closure schedule will run are being handled via the Barbican's own listings, so check there before turning up — capacity is limited and these free slots tend to go fast.

For travellers, this is a two-sided story. First, if you're in London while the conservatory is still open, prioritise it: it's free entry, a few minutes' walk from Moorgate or Barbican stations, and pairs brilliantly with the rest of the arts centre, from the gallery to the lakeside terrace. Second, if you miss the window, there's still plenty around it — the City's remaining post-war architecture, the Museum of London's former site nearby, and St Paul's a short stroll away.

Restorations of this kind usually mean years rather than months, so don't bank on a quick reopening. The consolation is that the venue is being invested in properly, which should mean a healthier, more resilient jungle when it returns. Until then, your best bet is the free cuttings event — and a potted reminder of one of London's strangest, most atmospheric interiors sitting happily on your desk at home.
