At 3300' elevation in AZ. Last year had 5 days of snow and 18 degrees for winder. Red Baja made it through beautifully without any cover protection. Summer here brings 108 plus, so it does need weekly, slow deep soak.

Using peat moss and crushed vermitculite for seeding medium, am attempting to grow from seeds.

First set of six planted did NOT set, grown outside in March. Out of Second trial of seeds, One and only one has come true; grown outside in April. From Third trial of seeds (grown in May) inside of home, produced Bird of Paradise looking plants (am growing them to see "What is going to bloom" if anything). July 2014, am trying another 6 and will post when they are at least 4" tall. These seeds are fresh from the bush growing in my yard. All t... read more

I just bought this plant so I am unable to evaluate it at this time. It prefers a very dry location and would make an excellent plant to use in rock gardens, xeriscapes and wildscapes. It is a hybrid between the Pink Fairy Duster (Calliandra eriophylla) and the Baja Fairy Duster (Calliandra californica). It has been producing blooms constantly for weeks.

Update 9/25/05: I just found out that Calliandra can sustain leaf damage at temperatures below 25F (-4C) and are often killed when they fall to 20F (-7C) and below. We have had mild winters the past few years, but temperatures can fall into the teens here. I may have to keep this plant in a container just in case. The plant is doing wonderfully blooming almost nonstop during days upon days of 100 degree weather and no ... read more
