Gardeners' Notes:

Neutral nathanieledison On Apr 18, 2013, nathanieledison from Santa Rosa, CA (Zone 9b) wrote:

This is a gorgeous plant and I don't like to give neutral ratings - but grown as a houseplant in zone 9b/10a, it has a few problems. Imagine every small bug or pest you can and chances are your crossandra will be attacked by every single one. I grow it a foot away from a 120V grow bulb but put it outside when it gets warm. Beautiful, beautiful plant grown inside, but requires constant supervision

This is a lovely plant I keep indoors (had it outside but too windy) It is starting to grow more on one side and a bit lanky, do you need to prune them does anyone know?. I have never seen another one so unable to buy more until I do. I love them.

I grow this plant in the Dominican Republic. What fascinates me is that the seedlings even when just poking through, the leaves are as shiny as the adult plant.

I have this plant growing fine in Wisconsin summer. This is the first time I had this and not sure if this survives indoor in the freezing summer months.... so far it's growing well and blooming too :)

Positive nolainbloom On Jul 22, 2010, nolainbloom from New Orleans, LA wrote:

The Crossandra growing in our garden was originally planted in a container for the patio. Given our region's semi-tropical climate, we soon found that one plant had managed to seed itself freely resulting in multiple volunteers. Spent flower heads, if allowed to remain on the plant, will disperse seed. The dry pods, when ready, are triggered to disperse during a watering or a rain shower with a "pop" explosion, sending seeds in all directions - thus our many volunteers. We now treat this plant as naturalized perrenial allowing it to flourish where ever it wishes. Several plants are growing from last season and even survived our unusually severe winter (four consecutive days with temps dipping to 26 degrees).

After all the comments about the seeds self sowing and becoming a weed, I have had no luck at all with seed set! I have searched for the plant year after year, (its not easliy available in this area). It blooms well and does great through summer.It never sets seed! I move it indoors along with my other tropicals, it dies not survive ! That is the only reason for my Neutral rating, otherwisw a great plant.

However, one of the outside cats is getting high in the pot of it every night until he falls out of the pot! Thus, I am having trouble keeping it upright.

This was my first time to grow this plant---so pretty!!! We had sever drought this year. I never one time watered this plant. It was in full sun all summer. It is now October, and it is still glossy green and blooming!! I am saving seed in case it does not return next year on its own. Love this plant---want more of it next year!!!

My experience has been similar to Mike's. I planted the crossandra in 2005. It seemed to die out, and now, this year, it has suddenly reappeared . . . everywhere, like a weed.

I've changed my rating to negative after having it grow here for more than a year. It looks nice and it will grow anywhere, but it ended up spreading like a weed and choking out some of my other plants. Unless you want to completely fill in an area, be very careful with it. I just had to remove some of them.

In south india, orange kanakambaram flowers are tied with jasmine into short beautiful lengths and sold in street stalls to decorate the hair with. Kanakambaram and jasmine are also sold outside of temples to use as offerings.

Great house plant, too! When you put water on the seed pods of this plant, they POP out, sometimes as far away at 12 feet! The best way to harvest the seeds is to put the dry seed pods in a jar, add water and place your hand over the rim (very quickly) to keep the seeds from popping out, and then lay them out to dry on a paper towel! You'll get a higher germination rate if you keep the seeds and soil at 90 degrees (and takes 10-14 days)! Seeds are hard to find sometimes.
