Took a month and a half to turn bushy but they were prolific and added so much life with zero maintenance
Which best describes you as a gardener? IntermediateBIBotanical Interests11/19/25Hey Kane,
Thank you so much for sharing your thoughts. We're thrilled to hear that your Oriental Nights Sweet Alyssum turned out to be such a prolific performer for you!
Sweet alyssum can definitely take its time to really get going and fill out into those gorgeous bushy mounds, so we totally understand that month and a half wait feeling like forever when you're eager to see results. But it sounds like your patience really paid off! Once they hit their stride, sweet alyssum just becomes this amazing carpet of blooms that keeps going and going.
That's exactly what we love to hear about the zero maintenance aspect - Oriental Nights is such a reliable variety once it's established. There's something so satisfying about plants that just do their thing and keep adding that pop of color and life to your garden without needing constant attention. Sweet alyssum is perfect for those spots where you want continuous blooms but don't want to be out there fussing with them all the time.
Your experience with the timing will be super helpful for other gardeners who might be wondering what to expect during those early weeks when the plants are still getting established!
Keep on growing 🌻️
