When is a “rose” not a rose? When it belongs to a completely different family than roses. Roses (Rosa) are woody shrubs in the Rosaceae family. Most of us recognize a rose without even thinking about it.
So why do so many other flowers have “rose” in their name? Who knows. Maybe because of the romance and sentimentality associated with a true rose.
Ross Moss (Portulaca Grandiflora) is considered an annual, but is a perennial in our area. It is a member of the Portulacaeae family.
Even in a plastic pot on the north side of the house, it returned after a cold and long winter this year. Rose Moss can’t tolerate our heavy clay soil, so it needs a pot with good drainage.
Desert Rose (Apocynaceae Adenium Obesum) is actually a succulent member of the Oleander family.
One of its characteristics is the formation of a bulb shape at the base of its stem as it ages. This one only has a slight bulge so far.
Mexican Tuberose (Polianthes tuberosa) is a perennial related to the agaves. Polianthes means “many flowers” in Greek.
They don’t usually start blooming here until August, when the heat has been around awhile. This picture is from last year. The temps, as well as the humidity, have hit high gear, so they might be blooming in a month or so.
Texas Rock Rose (Pavonia lasiopetala) is a member of the Mallow family. It is a small shrub that needs little moisture. Mine doesn’t get much bigger and rarely blooms, maybe because it’s in a bed that gets watered. It could also be that the amended soil in the lasagna bed is too good for it. Never thought I’d say that about anyplace in my yard.
Rose of Sharon (Hibiscus syriacus) is in the Mallow family. It is also known as althaea.
More pictures show the abundance of flowers.
All the bushes in the above pictures came from a friend’s cuttings. She got them from her sister in Michigan.
This is a different variety of Rose of Sharon that I ordered from a catalog. Nice color and ruffled center.
Doesn’t even look like the same flower. All Rose of Sharons are hardy, hardy, hardy. Not much water is needed to live, but it is necessary for them to bloom.
What do all these plants have in common? They are drought tolerant, pretty, and thrive in the heat. Despite their names, they are not in the rose family. Even a stone is called a rose. If you use your imagination, a rose shape can be seen.
Desert Rose is a variety of gypsum that forms in the spaces between sand particles. It traps the loose sand in a unique flower-like crystal structure. They tend to be small. These are 1.5 inches across.
Rose rocks are found in Tunisia, Algeria, Canada, Saudi Arabia, Jordan, and in central Oklahoma.
Oklahoma rose rock was formed during the Permian Period, 250 million years ago, when western and central Oklahoma’s shallow sea coverage was receding. It is the official rock of Oklahoma. Didn’t even realize that states had designated rocks.
“I once had a rose named after me and I was very flattered. But I was not pleased to read the description in the catalogue: no good in a bed, but fine up against a wall.” Eleanor Roosevelt
