I love the tropical vibe these Hibiscus flowers bring to my garden! The colors are rich, and the petals are so soft. I just wish they bloomed a bit faster.
The seeds arrived fast, and I�m pleased to report they all germinated! The flowers bloom beautifully and last quite a while, which is a plus in my garden.
I added these to my flower bed for some diversity, and they really stand out. The color and size of the blooms are impressive, and they�ve been easy to care for.
I planted these seeds in late spring, and by mid-summer, they were flourishing! They made a lovely addition to my flower bed with their vibrant color.
These flowers were a hit with the pollinators! I planted them in a sunny spot, and they quickly drew in bees and butterflies. They�re beautiful and beneficial.
