    Full sized flowers on a dwarf plant!

    Meet Pugster Blue® - it's a whole new look for butterfly bush. This compact plant reaches just 2'/.6 m tall and wide but has the large, full flowers normally seen on a much larger plant. It blooms non-stop from early summer through frost with true-blue flowers, each with a tiny yellow-orange eye in the center. Thanks to thick, sturdy stems, the Pugster® series offers vastly improved hardiness and winter survival over other types of dwarf butterfly bush.

    Top three reasons to grow Pugster Blue® butterfly bush:
    1. Appealing true-blue flowers add hard-to-find color to any type of garden or landscape.
    2. It produces full-sized flowers on a compact, dwarf frame.
    3. Thick, sturdy stems ensure better winter hardiness in zone 5 than other dwarf butterfly bush.

    • I purchased this shrub mid-July last year (19). It was GLORIOUS!! Beautiful large blooms and many secondary blooms, plenty of butterflies visiting & no bug problems. I was concerned about overwintering but, it began leafing out, nice and full....However, something was eating the leaves that I didn't see until it was in bad shape. I couldn't find any bugs, so I sprayed it with the same chemicals I use for bud worms. Now I realized I should have gotten something for spider mites. The chewed up leaves are my fault but the buds are forming now and actually starting to open, however, they are SOOO much smaller than last year! Am I underwatering, overwatering, not feeding them properly? I want my 2019 bush to come back!!

      Satisfactory Average performance, met expectations but not outstanding.
    • The pugster blue butterfly bush produced lots of leaves but very few flowers. The flowers that have bloomed are brown. It does not look anything like the pictures. I did put them in a pollinator garden and was hoping to attract butterflies. Even other pollinators ignore this shrub. Very poor performer.

      Unsatisfied Did not survive, inferior performance or did not bloom well - won't grow again.
    • I love the pugster series! They are prolific bloomers! This is my second year having them in the ground. The blooms are much bigger the second year and they leaves are much larger. The plant has an amazing fragrance! You do have to deadhead a lot but I don’t mind because I love the butterfly bushes. However, they are extremely susceptible to spider mites. It even says so on the professional information, which I didn’t know and now I have planted 7 in close proximity. It’s also hard to spray all of the leaves because the plant is so compact, the laces are so large and there isn’t good air flow. I would definitely consider them to be very high maintenance, especially since I try to garden organically. Overall I am in love with them but I will most likely not plant anymore.

    • I have been gardening in excess of 50 years. I have considerable experience propagation and raising shrubs. I purchased a 3 gallon bush a week or so back. It was heavily branched and covered with bloom buds. I brought it home and set it in the garden. I watered the area. Shortly thereafter I noticed several broken limbs. Investigation revealed that the weight of the wet limbs had caused several of the lower limbs to split. This would not have happened in the nursery because the plants would have been close to one another providing mutual support. Hopefully, once the plant has become established, it will fill out again. No observation yet on the blooms.

    • I bought two of the pugsters this year and have been very pleased by their size, flower color, and continued blooming power for such a long time. I plan to buy more...!

      Outstanding My favorite plant, I recommend to others all the time and explain the reasons why I like it so much.
    • Glorious. A stand out plant in our pollinator garden. The old blooms turn dark blue, almost black. Very dramatic appearance. Full, dark green leaves.

    • I planted this for the first time in eary June and it has bloomed without stop all summer. I deadhead flowers every other day to keep the vibrant blue color. The butterflies love it too. I definitely recommend this plant.

    • My new plants have been covered in blooms (and butterflies) throughout this long hot summer. At first, I overwatered and caused some leaf yellowing and leaf drop because I couldn’t imagine any new planting getting through so many hot rainless days without help. When I cut back on water, the leaves returned to health. Flowering could not be better, and the fragrance is lovely. Planted alongside some purple coneflowers and native yellow milkweed. Very happy.

      Above Average Superior performance, among my favorites, would recommend to others.
    • I bought this because I love blue flowers and wanted a smaller Bush. It has grown very well, but it is bigger than advertised. Mine is 4 ft wide and 30” tall. The negative is that is is not self cleaning and I’m continuously having to clip off browned flowers. Since it is a prolific bloomer, the plant never looks pretty as it’s a sea of brown mixed in with the blue. I’m deadheading every 2 weeks.

      Marginally Adequate Performed below expectations but may be willing to try again.
    • I bought this beautiful blue dwarf blue butterfly bush three years ago. I have had no problems and given essentially no care after it rooted. I have it in a rock garden in central Texas. The blooms are very large on this compact bush and are outstanding! Very low maintenance. The blooms are very dark blue and lighten slightly the longer they are in bloom. A real winner and I highly recommend for smaller gardens. Be sure to plant where you can enjoy it from a window, your porch/patio.
