Other flowers are mentioned in the Bible such as the "rose" that was actually a narcissus badly translated from Hebrew (Isaiah 35: 10-2). Ask your pastor to verify this. There are the "flowers of the field," "blossoming vines," and the "rose of Sharon."
We also find that Solomon's Temple was decorated with carvings of "open flowers."
WERE THERE FLOWERS IN THE GARDEN EASTWARD OF EDEN?
We certainly like to believe that there were beautiful flowers there. However, in spite of many paintings of the massive garden eastward of Eden, there is no Biblical record of any flora there except for trees. See Genesis 2.
However, there are alway legends to spare. One of thse is a legend that Lilies of the Valley grew up wherever Eve's tears fell as she was banished from the garden eastward of Eden.
Another claims that the only plant surviving from the garden eastward of Eden following the disobedience of Eve and Adam is the Lign Aloe. This tree can grow to the height of 120' and has a girth of 12 '. Being a tree it could have easily have been in the garden.
The Rose, according to another tradition, did not have thorns in the garden eastward of Eden. After the sin of Eve and Adam the rose continues to grow around the world to remind us of the splendor of paradise. The rose has prickles rather than thorns. Prickles can be shoved off a cane with pressure of a thumb. A rosarian at the Smithsonian Castle rose garden in Washington D.C. shared this with the writer many years ago.
Notice we mention the garden as the garden eastward of Eden. The garden was not in Eden. A river flowed from Eden into the garden eastward of Eden. See Genesis 2. God placed Adam then Eve in the garden eastward of Eden.
God prescribed incense to be prepared in a specific manner and burned in Solomon’s Temple. It was made of four spices: galbanum, which looks like yarrow; onycha that is called rockrose with petals about 3” across; stactge or myrrh; and frankincense.
The first two are flowering plants that were familiar to many in the Holy Land.
