    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.

    • I have two of these shrubs and they are a workhorse in my garden. I've even moved them a couple of times to get them right where I want them. They overwintered find here (7b) and bloom all summer if I give them a light deadheading/sheering after the first bloom. The blooms are beautiful. I now want to expand my Spirea collection!

    • Just purchased and love the color. Curious if you have to cut these back in late winter early spring like a regular sized butterfly Bush?

    • The color of the flowers is absolutely stunning, but these are not as cold hardy as they claim. I am a landscaper and planted many of these for customers last year. Can’t tell you how many people have complained about them not coming back this spring. I planted one on my property and it’s just starting to come up from the ground and it’s almost mid June. We are in zone 6b so not sure why this is happening. I feel like proven winners should reimburse or give credit for other plants.

    • I am very disappointed in this shrub, although it was beautiful in the first year I had it, it has died this spring. I have two butterfly bushes, one came back this spring and the other didn't This is just pretty weak and poor for proven winner.

    • I got my Pugster blue from Lowe's at the beginning of the year. I planted it in a great big huge pot very average soil made sure it drained good had lots of holes in the bottom. Set it in the front where I got all day son seemed slow to start but I hung in there make sure I did not overwater! And then this year's rain started and there were many days when it rained every day! We let it dry out did not water it at all water never stood in the pot. And now all I have is crispy dry leaves that crush on your hand sounding like fall leaves. For a $43 plant I would not do this again. Was not a proven winner for me.

    • Absolutely stunning. Purchased as a memorial to our beloved pug. The blooms are prolific beautiful. Chosen for its dwarf quality so it could go in a large planter. I accompanied this plant with lemon yellow calibrochoa and the affect is mesmerizing against the first plum, the deeper blue/purple blooms.

    • I bought the pugster blue in the spring, but did not plant until in late June when the weather was quite hot. I was concerned it may fail to thrive. I was wrong. It took right off and looks very healthy. I look forward to next year when it will be bigger. This is my first 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!!

    • 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.
