This year October 26 is the Feast of Christ the King.  The Mass propers can be found at Usus Antiquior here. The liturgical color is white.
Above are Gemma's very lovely altar flowers for this feast (from 2020).  There are many more images here.

October 15 is the feast day of St. Teresa of Avila. In a vision, Teresa received a veil and necklace from Our Lady and St. Joseph. Read more at Fountain of Elias.

Upcoming on October 15 is the feast of St. Teresa of Avila.  Here is an interesting facet of this great Saint: 
One finds in the writings of the saints, and in art, powerful figures of speech depicting God as a lover in ardent pursuit of the human soul.  An example is Francis Thompson's poem, The Hound of Heaven.
St. Teresa of Avila, however, in writing about contemplative prayer, reverses the chase.  She uses a breath-taking metaphor where the human soul is a chess player seeking to capture Christ the King:
"I hope you do not think I have written too much about this already; for I have only been placing the board, as they say. You have asked me to tell you about the first steps in prayer; although God did not lead me by them, my daughters I know no others, and even now I can hardly have acquired these elementary virtues. But you may be sure that anyone who cannot set out the pieces in a game of chess will never be able to play well, and, if he does not know how to give check, he will not be able to bring about a checkmate. Now you will reprove me for talking about games, as we do not play them in this house and are forbidden to do so. That will show you what kind of a mother God has given you -- she even knows about vanities like this! However, they say that the game is sometimes legitimate. How legitimate it will be for us to play it in this way, and, if we play it frequently, how quickly we shall give checkmate to this Divine King! He will not be able to move out of our check nor will He desire to do so.Source:
"It is the queen which gives the king most trouble in this game and all the other pieces support her. There is no queen who can beat this King as well as humility can; for humility brought Him down from Heaven into the Virgin's womb and with humility we can draw Him into our souls by a single hair. Be sure that He will give most humility to him who has most already and least to him who has least. I cannot understand how humility exists, or can exist, without love, or love without humility, and it is impossible for these two virtues to exist save where there is great detachment from all created things.
"You will ask, my daughters, why I am talking to you about virtues when you have more than enough books to teach you about them and when you want me to tell you only about contemplation. My reply is that, if you had asked me about meditation, I could have talked to you about it, and advised you all to practice it, even if you do not possess the virtues. For this is the first step to be taken towards the acquisition of the virtues and the very life of all Christians depends upon their beginning it. No one, however lost a soul he may be, should neglect so great a blessing if God inspires him to make use of it. All this I have already written elsewhere, and so have many others who know what they are writing about, which I certainly do not: God knows that.
"But contemplation, daughters, is another matter. This is an error which we all make: if a person gets so far as to spend a short time each day in thinking about his sins, as he is bound to do if he is a Christian in anything more than name, people at once call him a great contemplative; and then they expect him to have the rare virtues which a great contemplative is bound to possess; he may even think he has them himself, but he will be quite wrong. In his early stages he did not even know how to set out the chessboard, and thought that, in order to give checkmate, it would be enough to be able to recognize the pieces. But that is impossible, for this King does not allow Himself to be taken except by one who surrenders wholly to Him."
We live in a time of vulgarity, irreverence -- and worse -- even in high places in church and state.  We must not join in this. We need to frequently turn our minds to Our Lord, Our Lady, the angels and saints, and everything we know to be good, beautiful, and true.
We need to sanctify our homes in every way possible. We need statues, art, candles, music, books, and flowers that call our minds to higher things and refine us.
We need etiquette in our homes as well as in public places.  We need to observe the proper order of things.
I hope that readers of this site will adapt information found here about church flowers to their "oratories" at home.  I hope  too that many will honor Our Lady with a Mary garden, whether it be outdoors or on a windowsill or table top.  And I hope that our Queen will inspire us to remember that we are only as good as we are in private when we think no one is looking and forget that all of Heaven can see us.
