    Snow Princess is cold tolerant and heat tolerant, she bloomed through the summer at the Dallas Arboretum and the University of Georgia trial garden. She is very vigorous so pair her with other vigorous.

    Snow Princess is a "heavy drinker" and will prefer evenly moist soil. It will be quick to show drought stress, but should bounce back quickly once re-hydrated. In a hanging basket you should be prepared to water often, maybe more than once a day during warm weather. Plants are easier to keep moist when planted in large planters. Due to her water needs Snow Princess is ideal for use in larger planters. In containers an application of continuous release fertilizer at planting is best. To help maximize performance use applications of a well-balanced water-soluble fertilizer (according to package directions) starting in mid-summer.

    Snow Princess will also perform well in the landscape where she will function as an annual, full sun, groundcover.

    While plants shouldn't need to be trimmed back, if she is taking over your walkway or is looking less than her best a trim can be administered at anytime. Use a sharp pair of scissors or pruning shears as needed.

    A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

    If there's one new plant that should be on everyone's list, it's Snow Princess, a unique breakthrough in the genus for heat tolerance and extended season performance. This sterile Lobularia is extremely vigorous, and because it puts no energy into setting seed it has an incredibly long bloom time. Creates a great hanging basket or window box and is a perfect filler in combinations.

    I am the landscape superintendent of a country club in coastal Wilmington, NC. Our club requires high quality seasonal color display beds that will perform all season long. I like to introduce new varieties in my designs that will meet our requirements. I was so impressed with Snow Princess that I purchased several flats for my house. I planted the Snow Princess behind a retaining wall in mostly sandy soil at the house. Snow Princess is thriving in our hot and humid summer and it kept up the bloom display until the fall. I want to thank Proven Winners for introducing such a fine plant.

    • I wanted to love these so badly! I had them in containers and in the landscape, made sure they got plenty of water, fertilized, and neither bloomed well. I’ve tried trimming them back to hopefully encourage new growth, and nothing. My plant in a container has a few blooms, but the ones in the landscape have about 1-2 blooms each. I don’t think I’ll try this one again.

    • This plant was a real stand out in my garden last summer. I purchased 5 plants in the spring and thought initially they looked so tiny in their pots. Once they got going though they did not quit! From a small plant in a 4" pot to glorious cascading never ending blooms. I had a number of people walking by ask me what they were and have started to receive messages from friends this spring asking what it was so that they can get some this year. The only problem I encountered was a a mid season infestation of spider mites, but luckily one good treatment with insecticidal soap and they were back to blooming. I'll definitely be planting this again. Hopefully my friends will leave some at the garden centre for me lol.

    • Fabulous plant! Bloomed all winter and spring and is still blooming at the end of summer despite our hot (many weeks around or over 100F) and dry weather. I have it planted where it does receive irrigation from drip lines and no overhead watering. I also have it in a container in full sun where it is still green and alive, but has stopped blooming - probably due to the heat and a more stressful environment. I suspect it will start blooming again once it gets a bit cooler. This beats regular alyssum by far!

    • Ordered 2 of these directly from proven winners among many other plants. One barely survived and one died from shipping. Proven winners (great customer experience for me) sent me a new one that also died. I do not recommend ordering these but instead finding them locally as they are too susceptible to drowning during shipping. However, the one that survived has thrived and is now taking over the pot, which includes supertunias and superbenas, and will need to be cut back. In just five weeks of being in a self-watering container which only receives fertilized water, it went from looking like a dying weed to being 12 inches high, 15 inches wide, and trailing 24 inches. If you are looking for a vigorous trailing plant, this is the one.
