  1. I’ve learned about Coleus and Ornamental cabbage from “Garden Answer” on Youtube. They garden in Oregon, not AZ, but you should check them out if you haven’t already. You two are my gardening favs!

  2. Love the onion guides. Going for it this cool season. Is growing garlic similar and do recommend any vendors? Thanks, Royal Norman

  3. Hi,
    I planted a blue salvia, salvia longispicata x farinacea, in October and it’s done really well until very recently. The leaves are developing grayish spotted patches. The other plants in the pot (nemesia, bacopa) are all thriving. It’s large pot Any idea what it could be?
    Thanks in advance for your help!

  4. Angela have you had success with Hydrangea. If so what variety and what is the best method and time to plant in the valley area.

  5. HI. when you list something as a wildflower, are you implying it is native or simply will grow without intervention?

  6. Hi Angela! I love your website! Thank you for sharing your knowledge and experience. Do you have a favorite nursery here in Mesa that you could recommend? I’m trying to find some salvia, echinacea, yarrow, coreopsis, daylily and Russian sage transplants. I’ve been to A&P nursery and HomeDepot but no dice. Should I try to order them online?

    1. You could try Summerwinds. All but the yarrow are usually available locally. I usually have to start yarrow from seeds.

  7. Angela, I love your website and all it has to offer. I have a question about what to plant in a raised bed against a North facing wall that barely gets any sun because of two ficus trees that are also planted in the bed? The soil is basically clay. I don’t want to spend tons of money amending the soil because we rent. There is also a small butterfly bush on one end that flowers but never gets much bigger. I appreciate any suggestions you may have.

    1. Difficult to grow without sun and good soil. You could look for native, non-flowering plants. Most flowering plants require sunlight in order to flower.

  8. Is vinca invasive here in Phoenix AZ? I just planted in ground as a border to the vegetable bed. Should I move them to containers?
