Maintenance Notes: 

Easy to maintain.

Beloved for its unique star-shaped, lavender flowers and interesting texture, this plant plays well with others in combination containers and landscapes. Once it gets started, it blooms right on through the heat of summer until frost.

  • First got one of these in 2009 under the Proven Selections category. Every year since then have gotten 2 including this year, its inaugural year under the Proven Winners badge. I see no difference but that's a good thing because these plants are unique, robust and very close to a true blue.

    These do require a tad bit more maintenance than say, lantana or verbena but just some water, regular fertilzer and a little relief from unusually hot summer sun and this chap will bloom prolifically and continuously all summer.

    One of my top 3 or 4 PW plants and would recommend if only for the unique shape and rich blue color.

    Outstanding My favorite plant, I recommend to others all the time and explain the reasons why I like it so much.

  • I plant this in the center of a 24 inch round pot - right in the center. I have 3 on my patio. Then I plant white begonias (4) around the Blue Star. It is an outstanding display for my patio! Not vivid enough for viewing from afar - but perfect for enjoying while on the patio. My entire garden is filled with Proven Winner plants - love them!

    Above Average Superior performance, among my favorites, would recommend to others.
