This is Hellboy*, he’s a very special chilli pepper. He’s part of the Space Chile Grow a Pepper Plant Challenge, which is run by Jacob Torres (who gets name-checked in episode 12 of Gardeners of the Galaxy).
Jacob works at NASA, on the Plant Habitat-04 project, which is going to be blasting chilli peppers up to the International Space Station next year. The chillies will be grown in the Advanced Plant Habitat, or APH, which is currently growing space radishes.
(The space radish experiment is Plant Habitat-02. What’s Plant Habitat-03 going to be, I hear you ask? Well, it’s going to be an Arabidopsis experiment. But it will probably be after Plant Habitat-04, because sometimes things don’t always go according to schedule in space.)
The idea behind sending chillies into space is that they would provide astronauts with a vitamin-rich flavour bomb to liven up all of their meals. After exhaustive testing, NASA chose a variety from Española, New Mexico, as its chilinaut, because it’s quite a small plant, and drought tolerant.
There’s just one teensy little problem. When grown in the lab, under space-like conditions, the peppers just don’t develop the same levels of heat (capsaicin) that they do under normal growing conditions.
And so Jacob has developed a citizen science project aimed at discovering how to give space peppers a consistent kick. People all over the world are growing the same chilli variety, in different ways, to find out what makes them hot. Jacob will collect sample peppers and test their capsaicin levels.
Hellboy is my experimental space chile. This photo was taken on DAP 26 (26 days after planting). I sowed 6 seeds in my AeroGarden (two in each slot), but most succumbed to mould issues. Hellboy was the only one to
Decorating for fall can go far beyond pumpkins and plaid. It's the season of rich textures, warm colors, and nubby knits. It's when you can layer enthusiastically, embracing your inner cottage dweller while happily sipping on your pumpkin spice latte.

Climb the cast-iron steps to the roof garden at the Reading International Solidarity Centre (RISC) and you can almost forget that you’re in the heart of the city. Just 30 by 6 metres, the garden manages to fill every vista and the breeze through the trees drowns out all but the loudest city noises.
Move over, Mark Watney, there’s a new space botanist heading for Mars! Ryan and I have just finished watching the new Netflix series Away, which follows (over 10 episodes) the quest of five international astronauts to be the first people to set foot on the red planet.

Over our heads, on the International Space Station, chilli peppers are blooming and being hand-pollinated by astronauts.
Join Emma the Space Gardener as she explores gardening on Earth… and beyond! In this episode, Emma recaps important spacecraft Arrivals and Departures and learns about growing nutrients and medicines in space. There’s a new plant experiment running on the International Space Station, and exciting news from ESA.
Myrtle (Myrtus communis) is a plant that has been on my ‘to grow’ list for years now, although it has yet to make an appearance in the garden. In the UK it is often grown as an ornamental plant, an evergreen shrub up to 3m in height and width. Given a spot in full sun and well-drained soil, it produces pink buds that open into white flowers with multiple gold-tipped stamens, followed by blue-black berries. It is hardy down to -10°C, and in mild areas can be grown as a hedge as it tolerates regular clipping. The species has the most frost tolerance; some of the named varieties are less hardy, but there are also smaller varieties that will tolerate being in a container long term, and so can be moved into more sheltered accommodations for the winter.
I found some time (and a blackbird-free window!) to spend in the garden yesterday afternoon. After pottering around looking after my seedlings, and repotting my salmonberry, I had to do some watering. April has been uncharacteristically dry, I don’t think we’ve had any rain to speak of this month. Everything in a raised bed is doing OK, but things in containers were starting to wilt.
Just over 3 weeks ago, I started the AeroGarden on its latest mission – rooting herb cuttings. Unsurprisingly, the mint was the first plant to take root, which it did in under a week.
Can we grow food on the Moon or Mars? That was the question that started Dr Wieger Wamelink, ecologist and exobiologist at the University of Wageningen in the Netherlands, on a research quest in 2013.
