  1. Whenever someone asks me what flower to give a child who wants to garden, or says they want flowers but have a brown thumb I tell them get zinnias. They come in a variety of sizes and colors. Cosmos are almost as good, and when my town planted them in a boarder in a newly designated park they grew to be taller than I was. Calendulas were planted nearby and they popped out from between the cosmos stems.

    Thanks for telling me what that flower is! My town planted them in downtown and I couldn't tell what they were. I knew they weren't a snapdragon taxonomically speaking but I didn't know what it was. Angelonia. I'll remember that now.

    Globe amaranth dries well too. Until my cat knocked the vase over and broke the stems. I'm much more interested in it's larger relatives though. A few love lies bleeding plants at the community garden garnered huge complements. They'd just put in an inclement weather shelter for the Homeless next to the garden and they loved the color. With an audience certain, I went all out to try and stun onlookers with perennials and edible flowers. And by the way, amaranth leaves can be harvested, though I'm not sure if globe amaranth is edible. There are also wild varieties that can cross pollenate with domestic ones, so keep your eyes pealed the following year.

    Salvias are related to sage, and they're very hardy too. From what I've heard butterflies and humming birds like them. But I'd rather have plants that are less common, and salvia is sold everywhere.

    Sunflowers were the first garden plant I ever grew. I was six or seven years old and marveled at the giant plants bigger than I was. Last year at the community garden, I had the lady in charge leave a couple of dead sunflower stems behind for me. This year I want to see if I can cover them in scarlet runner beans. Sunflowers and Amaranth are often planted with the three sisters (corn, beans, and squash) to attract birds that would eat pest insects. Hopi Black Dye is one I'd love to try, but for now I'm keeping a few mammoth sunflowers and a packet each of autumn queen and a smaller many branched variety.

    I have a pot of Rudbekia, and I grew up calling them black eyed susans. Where I live they are a good indicator plant to tell me when to start looking for raspberries. As they bloom around the time wild raspberries start ripening. Almost every empty lot in town has wild black raspberries growing in it, and if it doesn't, odds are good you'll find wild grapes instead. Both fruits have very strong sour flavors, and make good jelly.

    I have a trailing foliage vinca that was leftover from my neighbors' planter boxes. They put them to the curb in a mass of sodlike roots and soil, and I snatched them up and simply laid the soil out in my garden bed and watered it as a way to transplant them. I'm at the edge of zone 3/4 and they still came back.

    Mexican sunflowers grow very well, and almost form into a bush when fully mature. They can get larger than a person (and I'm 5'3" so at lest that size), and they're a favorite stop for monarch butterflies. If you love monarchs, plant this flower. Once when i found a very cold monarch in deep shade in autumn, I picked it up on my finger and brought it to the sunny community garden where a mexican sunflower was growing. I put the butterfly on one of the flowers and snapped photograph after photograph before leaving it to its own devices and checking the other beds to see how they were doing. When I'd looked closely enough, I could even see it feeling around with its proboscis looking for nectar, and watched it drink. A few minutes later that monarch was well enough to fly away. That picture is on my phone as my background now, as it's one of my prized achievements in photographing my gardening pursuits.

    There are two kinds of basil that are my favorites that I want to draw attention to, but over the years I've grown ten or twelve different varieties. They are purple basils and tulsi basils. There are multiple kinds of purple basil and four kinds of tulsi (three breeds and a mut). Purple basils get darker and glossier the hotter and brighter the sun is on them. In full spread just wuzzling the leaves releases a potent basil scent, and the leaves are PACKED with flavor. In general itallian basils like the purple ones have white flowers, and asian varieties pink or purple, not so with the purple basils. Their color goes through and through, including the flowers. They grow slowly, so it's best to start them from plants and get cuttings.

    Tulsi basils are an asian basil much older than either thai varieties or itallian varieties. They come from India, and have a slightly higher tolerance to darkness than other basils. Their scent is unique, and so is their flavor, tasting of spices and fruit, but nothing specific I've been able to pin down. There are four varieties and two species of tulsi basil, O. Sanctum and O. Tenuifolium. They are also called Holy Basil because they were grown in and around Hindu shrines. They're used in ayurvedic medicine for issues with digestion and stress. The former is a medicinal property of all basils, but medicinal concentrations vary per variety. I've shredded holy basil leaves and blossoms fresh from the plant into my coffee grounds in the morning in summer, and it's a welcome ritual of the warm weather. In southern latitudes, basil is perennial, and can be pruned and trained into a shrub, and tulsi is no exception. Towards the end of the season use clear plastic to cover the plant in order to keep it warm, keep the covering low, or the hot air will rise out of the plant's reach. It will survive for a little while inside during winter, and may even thrive, but my apartment gets a lot of pests in the winter, so I haven't had the pleasure. I highly endorse this plant as both an edible tea herb, an ingredient in asian cooking, and a pleasant and stimulating smell and taste for hot tired souls.

  3. Hello . I live in Chandler Arizona my mom told me to follow your channel. Now unfortunately I didn’t see the plant I’m looking for on your list and I was wondering if you know how Chrysanthemums “mums” do in our summer months out here ? I have 8 huge mum plants that I fear won’t make it through the hot summer months and yesterday their leafs started taking a turn for the worst . Is it best I buy large pots and transplant them before summer ? My only thing is I don’t want to keep transplanting them from pots in summer back into the ground for fall winter and spring and back up for summer ? Please help need your advise !?

  4. Hi
    Your video was very helpful and the flowers were so pretty
    Thank you for the great tips and for sharing your knowledge of these flowers
    Happiness and good health to you and your family!!!

  5. Just finding you and amazed with your communication skills. To the point, clear and informative…thank you!

  6. what do you mean by thin those seedlings? can you elaborate please

  7. Thank you for the great examples and tips! I just picked up Angelonia from the nursery based on look, so it's great to learn that it likes the sun and heat.

  8. Cosmos is an great plant and easily transplant early in the year and reseed, especially orange cosmos.

  9. Very helpful information! I know more about growing summer flowers and believe I will do better the next year!

  10. I live in East Mesa. I have seedlings that are ready to plant outside but the temps are still under 45 degrees. What seedlings can take the cold? I have zinnias, cosmos, rudbeckia, hybrid poppy, tomato, zucchini, and hyacinth.

  11. I grow in Chico Calif and we have a similar summer to yours. Thank you for your info….especially the drip tube company you use! Can I ask how often you water your raised beds in the summer? Is daily too much?

  12. This video is my bible! I have literally watched it a dozen+ times. I keep coming back over and over to learn about the flowers I bought. Thank you!

  13. The application of prairie plants in our environments add nutrient to the soil and also serves as sustainability for agriculture systems which promotes our agricultural productivity. It is very important to have them around our farms in order to prevent erosions and add beauty to our farming environments.

  14. Majority of these plants were annuals am not sure if this coming back in my Zone 6. I believed I planted Cosmos a year ago but it didn’t come back!😳😩 so with Vinca and 4 o’clock ! I believed it’s still good to plant long draught perennials that will be coming year after year 😱😝😊

  15. Wonderful video & thank you for all the info! 😊
    I live in a semi-arid desert climate similar to yours so your videos are very useful to me. Many of the YouTube gardening channels I watch are located in areas that don’t deal with scorching hot summers (100+ degrees for 1-2 months straight) so some of the information they provide is not necessarily pertinent to my particular growing situation. You & John Kohler are my favorite desert climate YouTube gardeners. You are a great inspiration to me & I am very thankful for the content you provide 🌞💚🌻

  16. How often do you water zinnias? I live in Vegas where it’s dry and hot all the time. They started sprouting, but I don’t if I should water them once a week or a few times a week. I’m scared to overwater and underwater them
