    Features

    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.

    Pugster Blue butterfly bush is featured in our "Pied Piper" magazine advertisement.

    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.

    • This was my first butterfly bush purchase. I absolutely fell in love and have bought 7 more (each a different variety but mostly in the pugster series) It is so beautiful and the butterflies are always on it. Compact with large blooms just as described. One of my favorite plants in my yard.

    • I bought one in 2021 and loved it, Last spring (2022) I bought two from one source and five from another. They did great all summer, but the only one that came back was in a shaded/protected spot. They do not survive zone 6 winters. It wasn’t due to the heavy snow year because I shoveled the snow off them to avoid too much water.

    • I bought two of these on fall clearance last year and they weren't in the best shape, but since I had experience with butterfly bushes as I had one that survived my zone 5B winters for 20 years, I took a chance on them. I do not cut them back in the fall as leaving the stems holds the snow and helps to insulate the plant, plus I also add a layer of shredded leaves. I have clay soil, so I planted them high, and they came through the winter great. They were very late to break dormancy in the Spring much like Rose of Sharon, perennial Hibiscus, etc. as we had a cold Spring which just prolongs that dormancy until the daytime temperatures warm up and are consistent. They are now nice and bushy and in full bloom. I love the color blue of the flowers and the size of the plant. Much easier to place in the garden than the 8-10' tall ones. Also, the rabbits don't seem to like them!

    • I purchased the Pugster just this season and the plant seems to be doing well. I purchased this more compact plant because of space issues in this specific area where it called for something less wild & woolly but the plant is much too tight and compact compared to the traditional size. The compact nature seems to be the complete opposite of a traditional and is so far very unattractive. I think they took it too far in the compact direction. Also, compared to the traditional the blooms take a long time to replace even with deadheading so you go a long time without blooms unlike the traditional that blooms more profusely. Here in the East our Summers are short for pollinators so this is not a solid pollinator for us. It's still early to make the decision but as of today - I would not repurchase.

    • I planted 2 of these last fall and they are doing great here in my zone 8a location. They are growing well and constantly covered in flowers. The butterflies love them and the Pugster Amethyst butterfly bushes I have. I followed your advice and planted them high for good drainage. They get 10+ hours of full sun every day and love it. I highly recommend these plants.

    • I planted four of these in 2021. They did well for two years, but are now dead to the roots in 2023. We had a mild winter except for a single two day cold snap, so I think the cold killed them.

    • Have 3 of these now, they are the best colour of Buddleja in my opinion and the initial blooms are large, mine were about 7 or 8 inches long. Grew one in a container as a centrepiece and it did very well but did require a small amount of fertiliser in a pot to keep the leaves healthy and green.

    • In my zone 5 garden this plant has experienced severe dieback of the top growth. There are a few leaves starting to emerge from the base but I am not impressed with this result. Not recommended.

    • Planted Pugster Blue in a sunny location in my butterfly garden in spring of 2022. Loved the plant through the summer and fall. Here in late May of 2023 it is dead to the ground with no signs of life of any kind. Other buddleia are sending new growth from ground up. Nothing from Pugster, and I am afraid it has perished. This may be due to the freakish temperature swing we had here in Cincinnati on Dec.22, 2022, but most other buddleia at least survived at the root level. I will keep it in the ground hoping for regrowth, but confidence is low at this late date. An expensive experiment.

    • I planted my pugster in 2021 and I’ve been very happy with it! It’s too early to bloom yet this season, but it’s leafing out just fine this spring. I’m in northeast NJ. I have given it minimal attention honesty. Bio-tone when planted and that’s it.
