Mimosa Species, Catclaw Mimosa, Fragrant Mimosa, Pink Mimosa, Sensitive Mimosa

I have had what I believe to be Fragrant Mimosa (M. borealis) for over 10 years. I live just west of Austin, TX, on the Edward's escarpme...Read Morent, and normally in zone 8b. This plant is in a slightly raised rock garden in native calcareous clay (pH 7.2). It blooms well every April. It's in full sun, planted with other plants that don't need watering in late summer when we are normally very dry.
The local wild shrubs tend to be found on limestone hills with thin soils and excellent drainage, and are unfazed by extended drought. As such, I worried mine would be damaged by the abnormally wet winter we had. However, my plant is beginning to leaf out well.
I do want to note that the name Sensitive Mimosa or Sensitive Plant seems best applied to the sprawling, ground cover species whose leaves close together when touched. I have observed no such sensitivity in the leaves of shrub mimosa.

I have had a Mimosa tree for about 5 years, planted in a semi-protected area in full sun. The first 3 years it died back to the ground in...Read More the winter. Last 2 years it has not died back but has not bloomed yet. It has several stocks, not just one. We live in the Willamette Valley of Oregon, zone 6. There are quite a few big Mimosa trees locally, Albany, Eugene & Salem which bloom nicely, seems to do better in the cities where it is warmer.

This is a different plant than the sensitive plant mentioned above. I like this plant a lot. It grows wild on my land. it is beautiful ...Read Morewhen it flowers and lives up to its name if the wind is not blowing. A word of caution. It can make a lot of seed. I have a bug that bores holes in all the seeds so only a few missed seeds actually sprout below my small grove of brush. This is a welcomed symbiotic relationship from my perspective, but maybe parasitic for the tree since she keeps feeling like more and more seed is needed. IF you do not have this bug, you might be inviting a headache into your yard. Weeding under a plant who's nick name has catclaw in it has its dangers. I do like this plant thorns and all.

I have had my mimosa for 12 years and have never noticed spines or sharp edges.

Also I don't know when it starts to get leaves elsewhere but in West Valley where I live it doesn't show signs of life until the last of May. I do live higher up on the hills maybe I am more of a 4b than a 5. My other plants are at least 2 weeks behind my mothers who lives in the valley.
It doesnt grow like a weed in Utah due to the cold. In fact you have to baby it.
