anthurium ace of spades dark form Anthurium 'Ace of Spades' – Rare Black Velvet AnthuriumAnthurium Ace of Spades Thick velvet leaves give Anthurium Ace of Spades its dark, spade shaped outline, with pale metallic veins running through the surface. New growth can open with burgundy tones before hardening to deep green to near black shades. The plant grows as an upright clump, with firm petioles holding the foliage above the pot. This slower Anthurium responds best to steady warmth, filtered light and an airy root zone once it has settled.
Anthurium ‘Ace of Spades’
Thick velvet leaves give Anthurium ‘Ace of Spades’ its dark, spade-shaped outline, with pale metallic veins running through the surface. New growth can open with burgundy tones before hardening to deep green to near-black shades.
The plant grows as an upright clump, with firm petioles holding the foliage above the pot. This slower Anthurium responds best to steady warmth, filtered light and an airy root zone once it has settled.
Foliage features of Anthurium ‘Ace of Spades’
- Leaf shape: Broad spade-shaped blades with a defined base and a tapered tip.
- Surface texture: Velvety foliage that can show marks if leaves stay wet or rub against nearby plants.
- Colour change: New leaves can flush burgundy before hardening to a darker mature green.
- Venation: Pale metallic to silvery veins become clearer as the leaf expands.
- Growth habit: Upright clumping growth from a compact base.
- Root behaviour: Fleshy Anthurium roots need oxygen around them and decline quickly in dense, wet soil.
Growth and leaf development
This is a velvet foliage Anthurium with weighty leaves and a relatively compact base. New leaves are soft when they emerge, then firm up as the surface darkens and the veins become more defined. A settled position helps new leaves expand with fewer marks, especially while they are still soft.
A potting mix with bark, coco chips, coarse perlite or pumice gives the roots space to breathe. The plant should sit firmly in the pot, while the mix remains open enough for water to drain and air to reach the root system.
Care for Anthurium ‘Ace of Spades’
- Light: Place it in bright filtered light. Direct midday sun can mark velvet foliage, while very low light produces slower, weaker growth.
- Water: Let the upper part of the mix dry before watering again. The root ball should not stay wet from top to bottom for long periods.
- Humidity: Higher humidity helps new leaves expand more evenly, especially while the blade is still soft.
- Airflow: Humidity works best with gentle air movement, because still damp air can leave velvet leaves marked or spotted.
- Temperature: Keep it warm and stable, away from cold windowsills, winter drafts and sudden temperature drops.
- Substrate: Use a chunky Anthurium or aroid mix with large particles for drainage and root aeration.
- Feeding: Feed lightly during active growth. Flush the mix occasionally if mineral residue builds up from fertiliser or hard water.
Common issues with Anthurium ‘Ace of Spades’
- Brown patches on velvet leaves: Often linked to direct sun, water sitting on the leaf surface, low humidity or mechanical damage.
- Yellowing lower leaves: Check whether the mix is staying wet too long or has compacted around the roots.
- Stuck new leaves: Dry air or unstable warmth can make emerging leaves unfold unevenly.
- Soft roots or sour-smelling mix: The substrate is too wet or too dense and should be checked before more foliage declines.
- Fine speckling or dull patches: Inspect the undersides and petioles for spider mites or thrips, especially in warm dry rooms.
Safety for Anthurium ‘Ace of Spades’
Anthuriums contain insoluble calcium oxalates. Keep Anthurium ‘Ace of Spades’ away from pets and children who may chew leaves or stems, as ingestion can irritate the mouth, throat and stomach.
Name etymology and background
The genus name Anthurium comes from the Greek words anthos, meaning flower, and oura, meaning tail, referring to the tail-like spadix. The cultivated name ‘Ace of Spades’ is used for this dark velvet selection with spade-shaped leaves, burgundy new growth and compact upright habit.

Native American history at its best!
Format: Hardcover
Kent Blansett's engrossing story about the life & times of the famed Mohawk activist Richard Oakes is Native American history at its best. I appreciated the well-written context provided about the birth, growth and impact of the Red Power Movement and the pivotal role that social justice activism played in the rise of modern Indian nations in the United States today. This scholarly work helps us understand modern Native America and is a "must-read" for every Native American Studies student and scholar, as well as readers interested in important American social justice movements.

Excellent book on ML
Format: Paperback
This is a great book on machine learning. Topics covered are extensive - from beginner level to advanced topics including math behind different algorithms. However, not "all" algorithms are covered. Please go through the table of contents.
The first part - 11 chapters - covers machine learning concepts and second part covers advanced topics with Pytorch. There are lots of excellent code and they work!!
The quality of the book I received is excellent. I have gone through all 742 pages, and it has held up very well!!
I used Jupyter notebook to run all examples. I created a new notebook and copied and pasted the code and ran them. This approach worked very well for me. At the same time, I could experiment with my take on the code snippets and definitely added to my knowledge.
Only issue I have is on the second part of the book discussing PyTorch: (1) Some packages are a bit older version: e.g., transformer 4.9.1 whereas current version is 4.48+. It took some tweaking/recoding to get the examples working. (2) There is not much discussion on why certain architecture was chosen - e.g., number of layers, is there a rule of thumb on how to improve performance by changing these parameters? Even with CUDA the code run for a long time. Therefore, experimenting with different values of parameters become too time consuming. (3) On the same note, if I can achieve test accuracy of 90%+ using logistic regression and almost the same (perhaps one or two percent better with PyTorch with IMDB movie review dataset and that two much faster why should I use PyTorch for this dataset? Obviously, PyTorch is for certain types of problems. Discussions can be included by not adding to the exhaustive (and apt) contents.
Personally I was disappointed by lack of any example on time series.
Must have for ML practitioner as a reference and guide.

Excellent Textbook for Hands-On Learning of ML
Format: Kindle
This textbook is for the serious life-long learners of machine learning. There are at least two ways to ‘consume’ this book.
For the expert in ML, this is a textbook to study as a clear comprehensive ML overview and then to dive into sections of interest or ignorance. The concepts are grounded in code examples and are well cited (with links) to sources. Further, this textbook is appropriate if you are TensorFlow-centric and want to broaden into cutting-edge ML models/tools coded in PyTorch.
For a new learner to ML, this is a textbook to DO (not just READ) with hands-on and brain-engaged. If you realize that ML is a key life-long skill for your career, consider this textbook as part of a daily learning habit (10-30 min).
From personal experience, my advice to the new learner is as follows… First, clone the GitHub repository, setup your Python environment, and study the textbook, while working through the notebooks. Go on tangents and break the code. Do this methodically as part of your daily learning habit, but do not hesitate to jump ahead several chapters to prepare for tomorrow’s meeting. There is enough excellent material here for a full year of ML adventures.
I did a similar strategy with Raschka’s first textbook. About four years ago, I had finished Andrew Ng’s Deep Learning Specialization as a student in his first cohort. I knew the concepts well but could not do the actual application coding. I was surprised how my Python coding improved by following Raschka’s clean and elegant style. And Raschka’s code examples were meaty enough to be springboards into working applications.
Several textbook editions later, what is different about this new edition?
First, it moves you through scikit-Learn (a firm foundation) to PyTorch, instead of TensorFlow. PyTorch is a better stepping-stone, both conceptually and practically. With PyTorch, you will go further with less energy, while being able to convert your efforts into TensorFlow as needed. In addition, most of the cutting-edge ML/AI/DL research is in PyTorch. It is nice to read a recent arXiv paper, clone their repository, click on the Colab tutorial, and replicate their experiments, along with picking up a ton of new coding tricks & tips. I am excited to work through these PyTorch sections to hone my skills.
Second, there is a clear recognition of model tracking and tuning practices. This is often a gap in other ML textbooks and courses. Once you progress beyond the simple demo examples in a lecture, you realize that the real work is experiments, more experiments, and still more experiments, so that you must understand what the model architecture and hyperparameters are doing to your dataset. There is good coverage of scikit-Learn pipeline, grid search, model performance, and the like.
Third, ML/AI/DL practice is rapidly evolving. Every week new ML packages/services become available that could save much grief on your current project. What is refreshing about Raschka’s textbook series is that he constantly adding cutting-edge topics because he likes to stay current and to help us stay current. Hence, this edition contains recent ML treats as: transformers, self-supervised learning, autoencoders-to-GAN, graph neural networks, DBSCAN, t-SNE (with brief mention of UMAP), and PyTorch-Lightning.
