During May, many people honor the Virgin Mother with May crownings and May altars. It’s also the time when Mary gardens begin to bloom, or be planted.
For example, there has been a Mary garden at St. Francis Xavier Cathedral for almost 10 years. https://www.thecompassnews.org/compass/2008-08-15/news1.shtml
In my own garden, partially shown here, the bleeding hearts (Mary’s heart in a Mary garden) and (in the background) periwinkle (called the Virgin’s flower in a Mary garden) started to bloom on Mother’s Day this year. Also blooming are lilacs (called Ascension flowers in Mary gardens) and tulips (Mary’s prayer.)
