Black Knight Dragon Tree
Botanical Name: Dracaena marginata 'Black Knight'
Family: Asparagaceae
Origin: Madagascar
Plant Type: Evergreen small tree / architectural feature plant
Overview
Bold, dramatic and effortlessly stylish, Dracaena marginata 'Black Knight' is one of the most architecturally striking plants you can add to an Adelaide garden or outdoor space. Its slender, upright stems are crowned with tufts of long, strap-like leaves in deep dark green with rich red-purple margins — a combination that deepens and intensifies with sun exposure, creating a genuinely dark, moody effect unlike anything else in the landscape.
Slow-growing and low-maintenance, 'Black Knight' thrives in Adelaide's warm seasons and makes an outstanding feature in sheltered courtyards, alfresco areas and large containers. It copes with Adelaide's mild winters but appreciates protection from frost and cold winds. Indoors or out, this is a plant that commands attention without demanding much in return.
Key Features
- Mature Size: 2.0–3.0 m H × 0.5–1.0 m W outdoors (1.0–1.5 m in containers); spreading vase form with age as stems branch
- Growth Rate: Slow — 10–20 cm per year; easy to maintain at desired height
- Foliage: Long, narrow strap-like leaves; dark green when young, deepening to dark purple-red with age and sun exposure; foliage colour intensifies in brighter light; evergreen year-round
- Flowers: Rarely flowers outdoors in Adelaide; when it does, small creamy-white fragrant flowers appear in summer; followed by yellow-orange berries
- Fragrance: Flowers lightly fragrant when produced; foliage not fragrant
- Seasonal Interest: Dramatic dark foliage year-round → stems branch and spread with age creating sculptural multi-stemmed form → occasional summer flowers in warm established specimens
- Wildlife Value: Flowers attract bees and pollinators when produced; dense foliage provides shelter for small garden fauna
- Tolerance: Drought-tolerant once established; heat-tolerant; coastal-tolerant; frost-sensitive — protect from frost and temperatures below 5°C; shelter from strong or cold winds; tolerates part shade; dislikes waterlogged soils and fluoride-rich water
- Planting Density: Plant as a single specimen or in groups of 3 at 60–80 cm spacing for a dramatic foliage cluster; ideal in large containers (40 cm+)
- Pet Friendly: Toxic to cats and dogs if ingested — keep away from pets
Where It Works Best
- Sunlight: Full sun to part shade; full sun deepens the dark purple-red foliage colour; tolerates bright indirect light indoors
- Soil: Free-draining sandy or loamy soils; excellent drainage is essential — will not tolerate wet feet; use a quality potting mix with added perlite or coarse sand for container growing
- Water Needs: Establishment: water regularly for first 8–12 weeks. Established: deep soak every 2–3 weeks in summer; allow soil to dry out between waterings; reduce significantly in cooler months
- Maintenance: Minimal pruning needed — remove yellowing or damaged leaves; prune stems in spring to encourage branching and a fuller habit; feed with a balanced liquid fertiliser every 4–6 weeks in spring and summer; avoid high-fluoride water and superphosphate fertilisers
- Lifespan: Very long-lived; decades with correct care and drainage
- Climate Zones: Best in warm, sheltered positions — coastal Adelaide, northern suburbs and protected courtyards; grow in containers in cooler foothills areas for easy frost protection
- Soil pH: Slightly acidic to neutral (6.0–7.0); avoid alkaline conditions
Landscape & Design Ideas
- Architectural feature plant for modern, tropical or minimalist garden designs where bold form and dark foliage create dramatic contrast
- Group three stems together in a large statement pot for alfresco areas, pool surrounds and courtyard entrances
- Pair with silver-foliaged plants such as Westringia, Artemisia or Leucophyta to maximise the dark foliage contrast
- Use as a vertical accent to break up horizontal planting schemes in garden beds and mixed borders
- Outstanding indoor specimen for well-lit living spaces, offices and atriums — brings the drama of the garden inside
Why You Will Love It
'Black Knight' is the rare plant that looks incredible doing absolutely nothing. The deep, almost-black foliage is genuinely unlike anything else in the garden, and the slow, sculptural growth means it just keeps getting better with age. Low-fuss, high-impact and effortlessly bold — it's the plant for gardeners who want drama without the drama.

This book will educate and inform! A+
Format: Paperback
Now in my 7th decade, I spent my entire career in the pharmaceutical manufacturing industry. I can attest to the veracity of Dr. Brawley's dissertation. The maxim that all physicians and surgeons promise is the essential promise to "First, do no harm." Dr. Brawley teaches that not all who purport to care for us and our loved ones adhere to this promise.
Just ask a vet. On the battlefield virtually all medical care is superb. Here at home, alas, it is not so.
Too often, not always, but way too often he is right. Here's the bottom line. If you're not comfortable with what your being told about your health, or that of a loved one, don't hesitate, find another MD who though you may not like what they may say to you, you trust them with your life. That is exactly what you're doing. Much of the seeming heroics in medicine/surgery are really about making or saving money for the drug industry, or hospital, or doctor, or insurance carrier, and not about saving your backside. Certainly not always, perhaps not even most of the time, but way too often.
Read this book and you'll be radically better equipped to understand just what may be driving the responses of the health care systems to your malady, and how you can assure the appropriate care for yourself or a loved one. Are there great doctors and hospitals out there? You bet there are. There are also those who couldn't care less about quality health care for you and are only focused on their own backside. This book will educate and inform you.

"More" is not "better"
Format: Kindle
I had the privilege of working with Otis during part of his training at the National Cancer Institute at a time that policies on PSA and mammography screening were being newly scrutinized with respect to risk/benefit. The notion that screening might actually do more harm than good was seen as absolute heresy and I fondly remember the wonder and amazement in Otis' eyes as he unraveled to me just how this counter-intuitive idea could be so. Twenty years later, the truths I learned from Otis back then are still not widely appreciated among patients, indeed even doctors more sadly. I eagerly snatched this book up not only because I knew Otis and expected a riveting review of healthcare but because my experience in pharmaceutical development has led me to participate unintentionally in some of the perverse systems of conflicts of interest that characterize our healthcare system. I am at a personal watershed and this book is a strong antidote for what ails me, i.e. I feel emboldened to take my career in the direction of a solution rather than continue to contribute to the problem. Written for the general audience, We Do Harm breaks the ranks of legions of doctors who are invested in perpetuating a broken but remunerative healthcare system by introducing specific and by no means isolated instances where patients have been harmed. This book is at once disparaging of blind trust of one's physician and optimistic in that some stars like Otis and microcosms like Grady Memorial can and do avoid patient-disadvantaged conflicts of interest. This book provides evidence and motivation for every person in every role they engage in in the healthcare system: patient, consumer, provider, insurer, politician. No one can escape the relevance and import of the key message of this book that "more" is not always "better." Until such time, if ever, that our healthcare system operates under transparency, this is a must read for all. That means you! Now! It can't wait! I am a believer that healthcare quality will come from the bottom up and not the top down and this book exemplifies this spirit; read it and be empowered to ask the hard questions as to who is motivated to provide what care and at what personal gain.

Helpful for nursing school and NCLEX
Format: Paperback
This book was helpful in my nursing school journey. I still use it and it breaks it all down in simpler terms to better understand the material. Highly recommend for med-surg nursing.
