I bought these as a first attempt at flower gardening, and they didn’t disappoint. They sprouted quickly and bloomed steadily without too much fuss. I love how they brighten up my small space.
My cottage-style garden needed more blue hues, and these seeds fit the bill. They bring such charm with their delicate flowers and natural look. They blend effortlessly with my daisies and cornflowers.
These flowers don’t demand much once they’re established. A little water, some sunshine, and they just keep blooming. The blue color pairs perfectly with my petunias. Definitely a must-grow for anyone wanting easy results.
I filled my window boxes with these seeds, and within weeks, I had cascades of tiny blue flowers spilling over the edge. They’re charming and make the house look so welcoming from the street.
I’ve grown nemesias before, but this ‘Blue Gem’ variety is definitely the prettiest. The blooms just keep coming, and they haven’t faded despite some hot summer days. Lovely scent as well, light but noticeable.
