Hi, I have gardened in Central TX and in E TX.
These are some fragrant plants that have done well in containers for me:
Stock, Lathyrus odoratus, and/or Evening primrose. Sow seeds in Dec thru early Jan. and protect from frost.
Honeysuckle, the wild white kind. In my experience, tame varieties like Pink honeysuckle, and those sold by plant sellers have no fragrance. Needs a 3-5 gallon container.
Crocus bulbs, preferably Saffron crocus. Plant Nov-Jan. and protect from deer, bunnies, squirrels, and human thieves.
Daffodil bulbs, types that specify they are fragrant. best planted Dec thru Feb
Freesia bulbs (best planted Nov thru Jan, protected from frost.)
Hyacinth bulbs (best planted Dec thru Feb, protected from frost.)
Narcissus, paperwhite. best planted Nov thru Jan, protected from frost.)
Nicotiana persica, flowering tobacco. Shade tolerant. Needs a 1-3 gal. pot
Gardenia, frost resistant type. Needs a 3-5 gal container and specialty gardenia soil.
Must be brought into protected area like a shed or garage in winter.
Mountain laurel Sophora sp. and Butterfly bush Buddleia. Both a 3-5 gal container. Buddleia prefers humid dappled shade such as near a pond/fountain
Chocolate Cosmos. Protect from deer & herbivorous wildlife.
Tuberose, night blooming Orchid Cactus/ Epiphyllum Oxypetalum, Ginger lily AKA butterfly ginger/ Hedychium coronarium, & "Root beer plant" Piper auritum: These are all tropicals. Need a 3-5 gal container and specialty potting soil made for tropical plants.
All these MUST be brought into protected 40F or warmer area like a home, or garage in winter.
Fragrant herbs, several, OTHER than Lavender which always dies due to heat.
Successful ones include:
Lemon balm (part shade)
Lemongrass
Beebalm/Monarda
Basils, various
Mints, various
Hope this helps!
