There’s been a change to my talk at the Chelsea flower show - it’s still on Friday May 22 at 3pm, but I am now being interviewed by designer Paul Hervey-Brooks. As it stands, the RHS is not planning to cancel the show, but if that changes I shall let you know straightaway. For the moment, I am holding off on the giveaway for a pair of tickets, until the situation becomes clearer.
Question of the week
Lynne asked me to recommend some houseplant books other than the oft-mentioned Dr Hessayon’s Houseplant Expert … here’s my top five.
The RHS Practical House Plant Book by Fran Bailey and Zia Allway (DK, 2018)
This is probably the modern-day equivalent of Dr Hessayon’s Houseplant Expert, with lots of practical advice for houseplant growers. The plant profiles are perhaps a little less detailed, and there isn’t a huge amount on plant propagation, but the projects are a nice addition, and are all very achievable even for the DIY-ice challenged like me!
The Care of Houseplants by David Longman (Peter Lowe, 1979)
This is probably my favourite of the five because it has really detailed entries for each of the plants it profiles, with beautiful line drawings of tasks connected with the plants it profiles: of which there are many.
It’s probably not the book for you if you want advice on styling, but for solid houseplant growing advice, it’s excellent.
Plant Love by Alys Fowler (Kyle Books, 2017)
Friend of the show Alys Fowler’s book is beautifully shot without looking like one of those unattainable houseplant styling books. She covers plant care and profiles key plants in detail, producing an all-round general houseplant book that’s hot on sustainability.
Alys’s writing style is accessible and clear, and she has a great way of spreading her passion for plants to her readers.
Oh, and she covers Crassulacean Acid Metabolism too!
What Houseplant Where by Roy Lancaster and Matthew Biggs (Dorling Kindersley, 1998)
If you are looking for a specimen plant for a big room, or houseplants with sword-shaped leaves, this is a great resource as it will help you narrow join your choices.
There are useful illustrations and plant profiles as well as a handy room-by-room section called ‘choosing the right plant for your home’.
The Indoor Garden by John Brookes (Guild Publishing, 1986)
Brookes - a giant of the British garden design scene, now sadly no longer with us - wrote this wonderful book on indoor plants in the 1980s, but it still stands as a great design resource.
Some of the ideas may not have stood the test of time, but do check out the instructions for making a moss pole, they really are far superior to the poles you can buy today! You’ll also love the flat lays of gorgeous houseplant leaves and the delightful eighties styling of some of the rooms.
Want to ask me a question? Tweet @janeperrone, leave a message on my Facebook page or email ontheledgepodcast@gmail.com. The more information you can include, the better - pictures of your plant, details of your location and how long you have had the plant are always useful to help solve your issue!

#OTLsowalong updates
Remember, there is loads of information on how to find seed, how to sow it and how to care for your seedlings - check my OTL sowalong page for more.
My recommendation for windowsill chillies are the compact, variegated variety ‘Trifetti’ aka ‘Purple Tiger’.
The golden-veined shamrock I am trying to grow from bulbils is Oxalis corymbosa aureo-reticulata, pictured left. I got mine from West Cornwall Carnivores on eBay.
Ashley was looking for stuff to grow that’s not cacti or succulents. Did you know you can buy airplants from seed? Online shop Unusual Seeds has various Tillandsia species for sale. Seedman.com has seeds of the ‘Gryphon’ Begonia and asparagus ferns in its houseplant pages.
Inside the seed
Seed is classified as either orthodox or recalcitrant: recalcitrant seed need to be planted quickly after harvesting, as they will not stay viable if they become dry, whereas orthodox seed can be dried and will still sprout. Chilli seeds, for instance, are orthodox, whereas avocado seeds are recalcitrant.
What’s a seed anyway? It’s a package containing all the materials needed to make a new plant: DNA, protein and starch. A seed is a propagule, which simply means a unit of propagation, be it asexual (eg a stem cutting) or sexual (seeds). Most seeds have three main parts: a seed casing aka testa, the embryo, which goes on to form the root, cotyledon(s) and stem, and the endosperm, which is mostly starch. The micropyle is a weak point in the testa where water begins to enter as the germination process begins.
Want to know more? The Book of Seeds is a lovely compendium of seeds from around the world. Strelitzia reginae (bird of paradise) is a standout for its bright orange aril which encourages birds to pick up and disperse the seed.
