Bought this plant at the Mercer Arboretum Sale in Houston,TX as Yellow Alder. Has been great. I have it in both pots and in beds. Have rooted it in water. Keep clippings which root in opaque vase on my desk at work and they keep blooming. Blooms all year in this climate.

I have not grown this plant. Yellow Buttercups, Yellow Alder, Sage Rose (Turnera ulmifolia) is native to Florida, Puerto Rico and the Virgin Islands. It was introduced to Hawaii and has naturalized.

This plant roots very easily. I saw this growing and had been admiring it for a while. I took a cutting and rooted it in water. It grew roots in a matter of days and I planted it in a pot.

This plant is quite lovely to my DH and I. We had several cuttings, and then noticed that it was popping up everywhere. On our last EarthDay we picked up lots of paperwork - and here was Tunera ulmifolia on the "invasive weed" list with a request not to plant it! Luckily we only plant in containers here, so we have kept it under control...but just wanted to post the warning.

I bought two yellow Buttercup plants at Home Depot in Orange City, Fla., and liked them so well, went back for two white ones. I have them in my yard in Deltona, Fla. They are doing well.
I bought this plant at a local Lowe's hardware store. But, about a year after planting, it moved from it's original place in my garden to replant itself in 2 differnent places in a different flower bed around the corner of my house! I'm sure the birds, or wind, spread the seeds. But, I was pleasingly surprised to find it offering up those marvelous yellow blossoms the next summer. The butterflies definitely enjoy the blossoms. It is easy to prune when necessary and it will readily bush back out with new growth.

I love this plant, but never knew of the connection between it and papayas. I'm going to take action on that one right away. Thanks for the great hint, Foodiesleuth.

Turnera ulmifolia (Cuban Buttercup) is the official flower of Cienfuegos, Cuba
I brought some from Miami to Hawaii (illegally, I might add) thinking to have a little bit of my home town in a new setting......imagine my surprise when I found this plant growing everywhere on the Big Island.
Grows easily from cuttings. Makes a wonderful filler and if planted near papaya trees, fruit flies will sting the bloom and not the papayas.

This plant is easily propagated from stem cuttings. Leafminers are sometimes a problem, taking away from the attractiveness of the foilage. Pinch off damaged leaves, or if serious infestation, cut plant down to woody stems. It will bush back out in no time.

This plant grows very well in Mobile Alabama. I've had a lot of success with this plant in both full sun and partial shade. Blooms stay open most of the day.
In Hawaii, Turnera ulmifolia is known as "Sundrops". It is a perennial and blooms year round, growng into a four-foot bush. The two-inch wide, bright yellow flowers open in the morning and are closed by noon. It has tiny seeds that sow prolifically. It will often grow out of a crack in the sidewalk after a seed germinates there.
