Grosso French Lavender (Lavandula x intermedia 'Grosso')
Grosso French Lavender, Lavandula x intermedia 'Grosso', is a vigorous French hybrid lavender valued for its long, arching flower stems, deep violet purple blooms, and intensely fragrant gray green foliage. Plants form a broad, mounded shrub that looks handsome even out of bloom, then send up tall flower wands in summer that sway in the breeze and fill the air with classic lavender perfume. With its strong presence, heavy flower production, and reliable performance in hot, sunny sites, Grosso French Lavender makes an excellent focal point, low hedge, or cutting garden workhorse in herb, cottage, and Mediterranean style plantings.
Distinctive Features
Grosso French Lavender typically grows about 24 to 30 inches tall and 24 to 36 inches wide, with a rounded, shrub like habit and a framework of woody stems at the base. Long, sturdy flower stalks rise well above the foliage and carry dense spikes of violet purple florets, giving a big, showy display when plants are in full bloom. Narrow, gray green leaves add fine texture and a silvery cast that blends easily with stone, gravel, and a wide range of flowering companions. Known for its strong fragrance and long stems, Grosso is a favorite for cut and dried flowers, sachets, and craft work as well as for bold garden color.
Growing Conditions
- Light: Prefers full sun with at least 6 hours of direct light daily for best flowering, strong fragrance, and a compact, sturdy habit.
- Soil: Thrives in well drained, lean to average soils; avoid heavy, wet ground and favor sandy or gravelly conditions that keep roots on the dry side.
- Water: Water regularly after planting to establish; once rooted in, water deeply but infrequently, allowing the top of the soil to dry between waterings.
- Hardiness: Well suited to many temperate regions where French hybrid lavenders are grown outdoors, especially when provided with sharp drainage in winter.
- Size: Generally forms a mound about 24 to 30 inches tall and 24 to 36 inches wide at maturity, depending on climate and care.
- Growth Rate: Moderate grower that fills in steadily and develops a substantial presence without quickly outgrowing beds or large containers.
Ideal Uses
- Bold Focal Point: Use as a single specimen or small group in sunny borders and herb gardens where its tall flower wands and strong scent create a natural focal point.
- Edging and Low Hedges: Plant in a row along paths, drives, or terrace edges to form a low, fragrant hedge of gray green foliage and purple bloom.
- Containers and Patio Pots: Well suited to large pots and tubs where the mounded form and tall flower spikes add height, scent, and movement.
- Herb and Cutting Gardens: Ideal in areas dedicated to herbs and cut flowers where you can harvest stems for fresh or dried use.
- Cottage and Mediterranean Gardens: Mix with roses, salvias, ornamental grasses, and other sun lovers for relaxed cottage combinations or set into gravel for a dry, Mediterranean look.
Low Maintenance Care
- Watering: After establishment, water when the top inch of soil is dry; avoid constant moisture or soggy conditions that can lead to root and crown problems.
- Pruning: Shear lightly after the main flush of bloom to remove spent spikes and shape the mound; avoid cutting back into old, bare wood below the leafy growth.
- Fertilizing: Requires only light feeding; in spring, apply a small amount of balanced, slow release fertilizer if soil is very lean, since excessive nutrients can cause soft, floppy growth.
- Mulching: Use a thin layer of gravel or coarse mulch around the base to improve drainage and keep foliage off wet soil, avoiding heavy organic mulches against the stems.
- Seasonal Care: In colder climates, provide excellent drainage and a sunny, sheltered spot; in late winter or early spring, tidy lightly to remove any winter damage and keep the plant compact and productive.
Why Choose Grosso French Lavender?
- Exceptionally Fragrant: Strongly scented flowers and foliage make it a top choice for sachets, drying, and scented garden paths.
- Long Flower Stems: Tall, sturdy spikes are ideal for cutting and drying and give impressive height and movement in the garden.
- Classic Color and Form: Deep violet purple blooms over gray green foliage deliver the traditional lavender look in a larger, more dramatic package.
- Sun and Heat Tolerant: Performs reliably in hot, bright exposures when planted in well drained soil or raised beds.
- Versatile Design Use: Works as a focal shrub, low hedge, or mass planting in herb, cottage, and Mediterranean style gardens wherever you want big impact, strong fragrance, and a dependable lavender presence.
With its vigorous, mounded habit, long violet purple flower spikes, and intense fragrance, Grosso French Lavender is an excellent choice for adding bold color, scent, and a strong focal point to sunny borders, hedges, cutting gardens, and large containers.

Astonishing, Fun, Entertaining, Fantastic
Format: Kindle
I consider The Martian my favorite fictional novel of the last 15-20 years. The movie was incredible in that they actually followed the book closer than 99% of other films based on books. It remains my favorite movie of the last 15 years or so as well. I don't know anyone (personally) that loves either of them as much as I do.
With that said, I was REALLY looking forward to Artemis. It was good...but, it was certainly not in the same caliber as The Martian was (at least not for me). I enjoyed it a lot, however and appreciated how author Andy Weir chose to go in a completely different direction and not just rehash another similar story, which I am certain would have been great as well.
As a result, I was cautious regarding Project Hail Mary. It sounded a little too close to The Martian, but yet, also different in that the circumstances simply could not be more opposite and the stakes so much higher. I'm trying to figure out the best way to summarize without giving too much away from this utterly compelling novel. As I read several reviews, I noticed a recurring theme: SCIENCE. Lots and LOTS of science. Holy cow, they were right. Many years ago I read Apollo 13 and Jim Lovell and his co-writer, try as they might, simply could not dumb down Orbital Mechanics anywhere near enough for me to have even a minor clue as to what they were attempting to say...I just skipped 90% of it and hoped that the sentences written afterwards, would help to make sense of what I had just skimmed over. I'm a lot of things, but a math wizard is definitely not one of them. Michael Crichton (Jurassic Park) had an amazing talent for dumbing-down the science of what he was trying to explain in ways that genuinely made sense (most of the time). Not everyone has this talent, and I would say Andy Weir falls squarely in between. He's certainly better than Jim Lovell, but not quite as good as Crichton. But then again, outside of a science textbook, I haven't really read anything with quite as MUCH science as Project Hail Mary. So maybe he's just as good, but he just puts more science into his books than Crichton, maybe that's it...? Either way, be prepared for a lot of astonishingly interesting science within the pages of this novel...and I DO mean a LOT. I don't say this to make you wary or steer you away...on the contrary, Andy Weir has a special talent for making hard science truly entertaining.
The book opens with an absolutely amazing and frightening premise: an astronaut awakes from an induced coma to find the only other two people on board have died at some point along their journey...but it gets worse. He has no idea who he is, or why he's on the ship, and oh yeah, they look to be a long way from home. A really, REALLY long way from home. In fact, the sun he sees isn't actually OUR sun at all. He's managed to leave our solar system entirely. And he has no idea why.
((Minor Spoilers)) The book goes through some clever flash-backs, which set the stage for why the mission happens, and slowly, carefully explains how they managed to get so far away from earth in such a short amount of time. Basically, earth's sun seems to be dying. At the rate of decay, we have maybe 19 years left before the gradual cooling has catastrophic consequences resulting in the death of billions (best guess). Why the sun is dimming is quite the conundrum in the first place. Turns out it really isn't dying, it's being killed by an outside source...which turns out to be easily the greatest find in history. It's alien life, and they are using the sun for food, essentially. It's alien life, but not intelligent life. But still, wow! ALIENS, right???
After this monumental discovery, and some tremendous research done by the most improbable scientist, the investigation into what is happening and why and what to do about it expands exponentially to other nations in order to pool all the resources possible to hopefully save the sun, and by extension, the human race as well. They learn. A LOT. A plan is put together, and with the help of the newly discovered microscopic alien life, which can also double as a power source (along with a few other nifty surprises), they begin to create one last, Hail Mary that could very well be the last chance we might have to save earth. It's audacious. It's dangerous, and it is absolutely critical that it succeed.
As our astronaut's memory slowly unravels, so does his identity: Ryland Grace. He's a teacher on earth. Just a science teacher. Not even a college professor. He's amazingly smart, though. But he's no astronaut...and certainly not one who would volunteer to go on a one-way mission to another solar system to "try" and save humanity. Yet here he is. Alone. light years from earth, trying to solve the biggest riddle in all of human history. Ryland accepts his situation, such as it is, with relative indifference (for the most part). It doesn't matter HOW he got here. He's here now and he may as well use that time to be as productive as possible, right? Along the way, he unravels even more information regarding the microscopic alien life which is slowly dimming our sun during some additional flashbacks. The aliens, dubbed, "Astrophage" are quite the galactic plague as it turns out. Stars all over the galaxy are also losing their light, all due to the little buggers. All that is, except one particular star named, Tau Ceti. Now why would that one star be unaffected by Astrophage, when every single star around it has been affected to some degree. The plan is to go there and figure it out and send the information back, hopefully in time to save the sun before the damage to earth is beyond repair.
There is an incredible amount of stuff going on. The story switches from Tau Ceti to flashbacks of how the whole mission was planned and implemented (which is VERY entertaining, especially Director Stratt, who may actually be my favorite character in the entire novel). Weir is becoming quite adept at building tension, and abruptly switching the story from Tau Ceti back to earth and building more of the backstory then switching back to Tau Ceti. Keeping it all in check and most importantly, interesting all while mixing in a healthy dose of science, which I am to understand is pretty much all genuine, is quite the juggling act. I have long known science can be astronomically entertaining (see what I did there?) when done right...but unfortunately very few people in a position to teach science actually know the best way to create that interest in others. I can say without reservation, Andy Weir definitely knows how to do it...at least in written form.
There is so much I want to say more regarding this truly phenomenal story, but I simply cannot without ruining a lot of the fun and surprises revealed along the way...and it is killing me to keep it locked in. Though I labeled a spoiler warning earlier, I don't think it gave away any more than what the author himself has revealed in interviews he has done regarding the book, and what you can glean from reading the summary here and just a couple other reviews. Tying all of that science together is truly astonishing to me. The creativity to put it into a novel that is remarkably exciting to read is nothing more than incredible talent. Kudo's to Andy Weir for not just hitting a home run, Project Hail Mary is a Grand Slam all the way. I truly did not want this story to end. By the way, I enjoyed the ending quite a bit. I don't know if everyone will. But it was fine for me. I think the ending screams "sequel" at some point too. A lot was left open-ended (IMO) and I wouldn't mind reading a follow-up to this. It doesn't HAVE to happen, but there are a lot of ways where the story could go if Andy chose to do it. Just sayin'.
Just run out and buy this book.

Wonderful
Format: Kindle
The amount of detail in this book is so interesting and the specifics of so much theoretical ideas revolving around true ideas makes it so fun to read. The writer does a great job and describing every situation enough where you get the point but not too much to try to bore you . The book is very easy to follow, keeps you on your toes, was pretty funny to me, and truthfully just a great book for anyone!

Read it in 2 days
Format: Paperback
This is science based science fiction. How refreshing to read science without turning the story into horror. Without a plethora of characters, it is easy to remember who is who. The story moves along well enough that I wanted to keep going. It us a p age turner in many respects.
All this said, there were too many crises suddenly resolved like some Star Trek episode from 1966. It reached the point where I said to myself, "OK, this doesn't matter. Move along, nothing to see here."
There was good humor, some surprising twists, and enough involvement with characters that I didn't want to put it down.
As science fiction goes, it was good like pulp stories go. It wasn't like Ursula LeGuin or Robert Heinlein but I would probably pick up the next book he writes.

A book worth rereading
Format: Hardcover
This was a book club pick. Honestly, I wouldn't have chosen to read this myself, but I'm glad that I did. I would have missed out on an incredible story.
I've been reading a lot of thriller and fantasy books lately, that I forgot how much I enjoy sci-fi. This brought it back for me. There's a lot of science-heavy discussions in the book and I loved it! When I got to a subject or term I didn't know, I would go online and learn more about it. I feel that Grace is a dork like me because he wouldn't curse. He had little anecdotes he uses in place of swearing. Something I definitely do myself!
A lot of the book is the MMC talking to himself. Surprisingly, it worked. There's so much humor that it kept the story going. There was not a lull. Usually I dislike info-dumping as an introduction to get all the background story told, but I didn't mind it at all. Maybe I'm being biased because I love science talk.
**SPOILERS AHEAD**
What makes the whole plot engaging is the fact that the plot doesn't seem too fantastical. It's something that could happen. There's a lot of ethics and morals involved in determining what should be done. I would hate to be in a position where I have to chose what's best for everyone. That's why Stratt is a necessary character. I hated some of her decisions and how she operated, but you need someone who's focused on the general welfare of humanity. I would be too focused on myself, my family, etc. As much as it hurts to admit, I'm selfish (and a coward) like Grace. I wouldn't want to die. But was it right for Stratt to force him on the mission? This could also be taken religiously. If God has a plan and things happen for a reason, is it our right to deter what's going to happen? God wiped out the world many times because of humanity's sins, what if this was God's doing? So many questions and debates on right vs wrong, ethics vs morals, and religion vs humanity made for a incredible book club discussion.
I love how this book ended. I wish I could continue reading about Rocky and Grace's adventures, it's that fascinating. However, I think Grace staying on Erid was the best outcome. If the roles were reversed, I don't think Rocky would have the same welcome. I feel that those in charge would have dissected and kept Rocky hostage, all in the name of science. Just as the Astrophage were first introduced, the first things the scientists did was poke and probe. Essentially torturing the Astrophage to see what makes them tick. I think Rocky would have the same fate.
Oh, and my favorite part is the relationship between Rocky and Grace. I cried so many times when I was reading. Scared that something bad was going to happen to either of them. Especially in the scene where Rocky busted out of his tunnel to save Grace. I got upset and told the book that 'if Rocky dies, I swear, this is the worst book ever!' And the scene where Rocky learns about radiation poisoning. How he slowly becomes aware of what happened to his crew, his friends. I was a mess.
This book is definitely one that I could go back and reread.
I did watch the movie afterwards. There's a lot of differences to adapt the story to screen, but it was okay. They got the humor down pat, but I didn't get the direness of the whole situation nor the special bond that both MCs had.

Excellent story
Format: Kindle
This book is worth your time. It is a great introduction to a variety of scientific disciplines without insulting the reader. It also respects and understands humanity, engineering, history and political science. Then it lays that foundation to tell the story of a unique friendship of two beings with mutual goals who have to communicate and problem solve together. Along the way, you can really contrast how Grace and Rocky do it, vice the Hail Mary team did it.
