Transcript

Jane Perrone (00:05) Hello and welcome to On the Ledge Podcast. I'm your host, Jane Perrone and in this week's show I'm visiting London's oldest botanic garden, the Chelsea Physic Garden, taking a potter around their glass houses with curator Emily Hazell. Finding out why some plants love living with ants.

How to make sure your succulents have not been poached and why geophytic pelargoniums might make an excellent addition to your houseplant collection.

More from the Chelsea Physic Garden shortly, but first a little bit of housekeeping. Thank you to those who've joined my Patreon of late. Rosanna has tried a seven-day free trial of the legend tier, and Katie, Steve, Brandon, Tim, and B all became free members. Thank you to all of you for supporting the show. It's much, much appreciated. If you want to go and check it out for seven days for absolutely free.

Please do that. You'll find my Patreon at patreon.com/ontheledge All the info is there, but do drop me a line if you've got any questions. And this is going to be the last episode of the show before I take a short break of three weeks. I am gonna be totally honest with you. I am really severely burnt out right now, having come.

Off of being made redundant, I had to hit the ground running straight away, and it's been a slog. ⁓ on top of well, I don't talk much about personal stuff, but let me just say I've been going through a migraine hell, if I can put it that way, and it's been a really difficult period dealing with up to 10 plus migraines a month for

Well, that's been going on for years to be quite honest, although it has got worse recently, and I'm finally on some medication that is working, which is great, but I am just really burnt out now. So I'm gonna be taking three weeks off. I will probably, if I get the chance, put out some on the ledge reloaded episodes. So bringing back old episodes for you to enjoy for those three weeks.

So there'll be something dropping in your feed, and then I'll be back on July the 17th with a new episode. I just can't keep going. ⁓ and you know, I keep telling myself it's okay to take a break because it is, and I'd say that to you too, as somebody who is phenomenally bad at taking a break and relaxing, that's exactly what I'm gonna try to do.

And if you miss the show, well, all I can say is, you know, do go and join the Patreon because there's so much stuff there. Extra leaf episodes, the first 50 episodes of the show, my audiobook, which if you join for the legend free trial, you get access to The Atlas of Deadly Plants. And if you become a super fan, you can access my other audiobooks, but you could also

Buy those individually as well. So there's just a wealth of content there. So if you're missing the show, please do go and check that out. It's a really great way of supporting me, particularly right now when I'm coming back off rebuilding my freelance business and it's tough. So I would love to have your support. It doesn't have to be in monetary form, it could just be passing on.

That you've enjoyed the show to s another planty person, or maybe leaving a review for my podcast or one of my books. It all massively helps me. So thank you for everyone who does all that already, and thank you to everyone who's planning to do so as a result of this. But yeah, burnout is no joke, and I need to take a breath. So I hope you understand. And yeah, I will see you on the other side. But for now, we're going back.

Into the Chelsea Physic Garden. Join me.

And that's not quite it. We also visited a small conservatory that plays home to a load of cacti, which we didn't end up talking about, but in addition to that, lots of carnivorous plants, which we did talk about. I had to check whether people outside the UK know what a flume ride is, a log ride, a water ride.

That's what I'm talking about when I say ⁓ talk about flumes at the start of this audio. So do enjoy this last chunk of chat from the Chelsea Physic Garden.

Join Emily Hazell, the curator of the Chelsea Physic Garden, as she guides us through the rich history and diverse plant collections of this historic London garden, including the tropical corridor, pelargonium house and the carnivorous plant collection.
