Bluebonnet Seeds

Sow bluebonnet seeds now for spring bloom.



All tropicals including allamandas, mandevillas, palms, pentas, blue daze, hamelia, hibiscus, esperanza, and plumbago will continue growing and blooming.

Summer Annuals

Annuals such as zinnias, moss rose, gomphrena, purslane, periwinkles, caladium and coleus will continue to flourish.

“House” Plants

Don’t forget that “house plants” are generally tropical in nature and love a nice shady or semi shady patio to put on the best show. Ficus, schefflera, corn plants, dracaenas, ivies, ponytail palms, and bromeliads all like heat and humidity.

      Hi Kathy – yes, we can grow lavender in CC, but it doesn’t tend to last more than 1 or 2 seasons. Spanish varieties are best. We’ll have some available Fall and Spring.

    I found these fall planting tips really helpful! Clearing weeds, adding compost, and nurturing the soil make a lot of sense. How often should I water during the rest period to promote those beneficial microbes effectively?
