No plant will last long in your summer heat without water so unless you have someone who can water it don't plant in a planter. If you do have someone who can water occasionally and more often when it's really hot Portulaca is a pretty carefree plant that will take an occasional dry spell. It's rose-like flowers are very pretty and will spill over the edge. My neighbor had some in her flower bed and they self seeded into the ditch in front of her house. Now she has a ditch full of portulaca that she ignores but we live in a much more temperate climate than yours.

Some tips for retaining moisture. If you can put your crook in a place where it's shaded for a couple of hours in the heat of the day. Not too much shade because portulaca requires sun but a bit of shade when it's hottest will help. Use a sphagnum moss liner. It will soak up water without keeping the roots too wet. They do make polymer water retaining pellets for hanging pots. They soak up and expand with water and release it slowly to the plant. Mulch the top of the pot so the soil is not exposed to the sun.

• Watering is not a problem I take care of the garden so I am there often just last year I used impatients and they had to be watered every day.

There are trailing coleus that are pretty summer tough. S/not be too hard to find

Did look up Portulaca and it seems very nice afraid of reseeding under the plant in the ground trying to avoid invasive types to not reseed in the garden. Coleus is a nice option

heavy watering can be an issue with putting too many small plants into a basket ... and then when they mature.. the pot ends up choked with roots ... and you cant keep enough water in the media ...

so you might be further ahead... if you start with less plants.. and just give them time to fill a basket ...

ken

was thinking of Nasturtium, Lobelia or Calibrochoa either of the ones mentioned might be a good choice

Sun or shade or something in between?

mostly sun

Nasturtium will also self seed as will most plants if they are not deadheaded. I don't think Coleus will take the heat if it's planted in full sun--they are a shade plant and even the newer varieties that are sun tolerant will only do well in part shade.

Geraniums are pretty carefree and won't reseed but they would require only a few minutes to deadhead. A zonal geranium or 2 in the middle(depending on the baskets size) with Ivy geraniums and ivy surrounding them would make a lovely basket. The benefit would be that they would take less watering because they like to dry out between watering and they take a lot of heat. I have geraniums on my back patio that get sun all day and sometimes I forget to water but they keep on growing and blooming

Wondering if they are any small tightly compact flowering plant that has an abundance of blooms that would be good for a hanging plant

does anyone know if Sweet Alyssum would do well in a hanging plant in mostly full sun. And if it comes in different colors

sweet alyssum peters out in hot TX summer. Ones planted in shade fare better

The cascading Vincas (Mediterranean Series, but there are others now) may work, too. They like heat and don't like to be overwatered. I've grown the Mediterranean Series (various colors) and they cascade nicely while still blooming at the "top" of the plant. There are newer Vinca varieties that cascade, but I've not tried those.

Tradescantia pallida would enjoy these conditions. Portulaca umbraticola.
