Just planted this tree last year and the Houston, Texas area. Watered it well the first several months. Not on the irrigation system in the yard but we have had a lot of rain lately. Now the leaves are turning yellow and brown and are falling off. Is this normal? Please refer to the uploaded photo of the problems we are having with this tree. Any suggestions on what to do?

We bought a wild Texas Olive Tree 2 years ago and planted in our front yard, semi-sun and sprinkler system that waters moderately. The tree has not grown any, and has tiny leaves and no blossoms. I planted a similar tree at my sister's home in Katy and it has grown "thru the roof".... what gives with my plant? I love the blossom and have a wonderful yard with many plants that are thriving. I just can't get this one to do anything.

I love this tree. It is so regal when it is in full flower. I just wish I could grow one . I got 2 cuttings today and placed them in water. I just need advise to see if this is correct to help it grow.

GREAT tree for hot, dry areas. I have a four year old texas olive that was a foot tall when planted. Today it is over 10 feet tall and 10 feet wide. Do not overwater this tree. It prefers conditions on the drier side.

There was a comment about wind breakage - from Florida, I suspect it was due to overly moist conditions. I live on the edge of a canyon where monsoon winds commonly reach 50+ MPH. This tree is not staked, bushy and has never budged or lost branches.

Please note, this tree is a huge litter maker. During colder snaps the leaves all dry up and shed but are quickly replaced by new growth. Flower drop is high and the olives get everywhere. Just keep it away from your pool and you'll have a beautiful, flowering, ornamental tree most of ... read more

There are two in Chappell Hill, Tx 77426 that have been growing here for many years. Neither have fruit. Where can I get another one that is non fruiting?

Beautiful, blooming tree. It's just covered in tough white flowers when it's in bloom for most of the spring and summer. It also blooms occasionally during the fall and winter, but smaller amounts. Pretty rare out here, so it really stands out amongst the seemingly endless yards of lantana, Mexican Birds of Paradise, and all. It's the centerpiece tree in our yard and gets lots of compliments. I'm thinking about putting up an information sign in front of it for the curious folks!

It does very well with very little care required in Las Vegas, Nevada. A great Xeriscape plant that's on the SNWA's list for the turf conversion.

I purchased this plant down in Rockport Texas while visiting parents. So many people have them on the coast and I liked the way it grew and how it seems to always be covered in blooms. Brought it home and planted it here in the Houston area and it has taken off like crazy! It's always covered in flowers and people ask what it is, which is what I like. However I'm curious about the fruit it produces. I've heard it's poisonous and others say it's not. I have not been brave enough to find out through taste. If anyone knows for sure, would love to know!

This plant does great here. It is drought and salt tolerant and none of our wild olives lost so much as a branch in hurricane Emily. It blooms non stop except for when we had the Christmas freeze in 2004, then it took a month or so to start flowering again.
The fruit is used in a Mexican cough remedy. Sometimes animals and birds eat the fruit and it makes them dizzy.
There are several large specimen trees in Cameron county.

I planted a small Anacahuita (Texas / Mexican Olive) in San Antonio, TX earlier this spring about 6". Currently it stands at about a foot. Amazingly, it is already starting to bud - I didn't expect it to bloom until it reached greater height. I have posted a picture of blooms from a 15' Anacahuita at my mothher-in-laws. I have seen this tree at 25' + tall in south Texas. It carpets the ground underneath in blooms.

This tree is an amazing hummingbird attractor! I'm currently watching six (yes, six!) ruby-throated hummingbirds feast on the bountiful blooms. And they have been at it all week long...

I love this tree for its constant blooms and beautiful bark. It is messy, though. My three-year-old is always out collecting spent blooms.

It begins to grow and even flower, but as soon as the wind blows a little, the entire head or at least various branches break off. I lose a year's growth with a puff of wind. It is more soft and breakable than hard and brittle. Prehaps it is too wet for it in Florida. Anyway, its headed for the compost pile.

San Antonio, Tx.
This small tree (can be grown as a large shrub) is native to the southern most tip of the Rio Grande region of Texas. It can be grown as far north as San Antonio, but may freeze to the ground during an exceptionally cold winter in this area. Tip dieback occurs in the mid twenties and it is hardy to 18 degrees. Grow in full sun for best results, but it can also be grown in areas with reflected heat. It is heat tolerant, adaptable to many soil types with good drainage and has a low water requirement. To encourage root development and growth, water frequently when young.

It bears 1.5 to 2.5 inch in diameter white, rufflely flowers with yellow throats from early spring through summer, but if it receives enough water it will bloom during all seasons. The ... read more

A native of Texas and Mexico this flowering tree is rarely out of bloom. It has a high drought tolerance and a medium salt tolerance
